Haven’t you and your team ever asked yourselves where potential for optimization exists? C-parts such
as O-rings, radial shaft seals, rubber buffers and hydraulic hose fittings are all items that – measured by
unit price – entail higher administrative costs than their actual order value. Yes, but that’s nothing new,
our customers would say. What can Angst + Pfister offer that would help improve our procurement process or our production process? Can Angst + Pfister products be integrated into existing C-parts logistics
systems such as kanban? Can we optimize our working capital with Angst + Pfister solutions? These are
the types of questions that our customers ask us on a daily basis. The following article gives you an
overview of the flexible possibilities that Angst + Pfister offers.

EOP
EOP (Electronic Order Process) is
the key to sustainable improvement in
supply chain management. Today’s
ERP systems make it possible to easily
dispatch orders to suppliers electronically. Angst + Pfister handles and
accommodates all of the current standards on the market. And that’s not all.
Angst + Pfister’s EDI solution (Figure 1)
is so flexible that it can be easily expanded to include electronic invoicing
(VAT compliant). The products EDI
Basic, EDI Advanced and EDI Professional give Angst + Pfister customers
a choice of electronic order processing
options. Such widely used and established EDI connections considerably
reduce customers’ administrative costs.

Many of our customers order standard
parts at irregular intervals due to
small production runs, variable product
ranges or maintenance, repair and
overhaul (MRO) work. In order to keep
procurement costs and warehouse

then import them, under the agreed-upon Angst + Pfister conditions, into the
customer’s ERP. Orders can be conveyed from the customer’s ERP via EDI
to Angst + Pfister with very little effort.
The order is then delivered on time to
the desired location, e.g. to a factory
in China, India, Ticino or the USA,
or to a construction site in the Middle
East. Our European logistics center
in Embrach, Switzerland, stands at the
ready.
C-parts logistics with partners
C-parts logistics should not be viewed
in isolation on a single supplier-bysupplier basis. The sum total of procurement needs is what really matters.
Working closely with leading C-parts
logistics suppliers of fastening technology such as Bossard AG, Debrunner Acifer AG, SFS unimarket AG
and Würth Industrieservice GmbH,
Angst + Pfister thoroughly examined
questions regarding technical and commercial responsibility in C-parts logistics and discussed points of contact for
product changes or technical problems.
In doing so, Angst + Pfister has been
able to develop pragmatic and efficient
solutions that offer customers the
greatest possible benefits. If the entire
supply chain management process is
optimized, individual projects could
see process costs reduced by as much
as 60%. The C-parts logistics systems
on the market right now offer customers
a diverse range of possibilities for
sustainable solutions that enable them
to concentrate on their core competencies. The processes are coordinated,
automated and create high customer
value through vastly simplified logistics
procedures (Figure 3). As the customer,
you choose your own C-parts logistics
partners, and Angst + Pfister takes
over the coordination of your C-parts
management. Utilizing standardized
C-parts logistics gives you and your
suppliers freedom to optimize your
parts procurement needs step by step.
Afterwards, topics such as product
redesign and parts standardization can
be collaboratively addressed, and
experience shows that this will help you
to achieve improvements on your firstcosts side.
We would be glad to discuss EOP
products in greater detail with you or
your C-parts logistics partners. Together
we will find solutions that will enable
you to reach your goals in supply chain
management and thus make you even
more successful on the market.

APSOsys® – seven steps
to a customized solution
APSOsys® is implemented in seven
steps:
• Step 1: Supply chain setup check
• Step 2: Engineering check
• Step 3: Supplier consolidation check
• Step 4: Volume assessment
• Step 5: Logistics check
• Step 6: Solution proposal
• Step 7: Solution implementation
Angst + Pfister first analyzes the customer’s current supply chain setup to
ascertain the potential for optimizing it.
A thorough examination reveals
how to minimize the number of suppliers. We examine, for example,
whether Angst + Pfister is capable on
its own of covering the customer’s
entire procurement needs. At the technical level, our engineers verify product authorizations, norms and specifications. The customer’s existing
logistics system is also carefully examined.
Finally, based on the analysis, the
experts at Angst + Pfister formulate a
solution package tailored precisely
to the customer’s needs and implement it into the customer’s existing
infrastructure.
APSOsys® combines the strengths
of Angst + Pfister
APSOsys® progressively bundles the
strengths of Angst + Pfister: profound
know-how, customized services, established relationships with partner companies and a unique product assortment. This combination of strengths
results in an efficient system supply
partnership that substantially reduces
overall supply chain costs.
But the customer benefits go beyond
simply lowering costs: APSOsys® liberates resources that were previously
otherwise tied up. The freed-up resources give customers greater capacity to concentrate on the essential –
their strategic procurement operations.

New machinery directive:
Enter the European market confidently
Jesus Moreno, Senior Engineer
Relax and let Angst + Pfister take care of it!
The countdown is ticking
away inexorably. On December
29, 2009, the new European
Machinery Directive 2006/42/
EC goes into force. There will
be no transition period during
which the old and new directives can both be applied since
the European legislature is
very strict here. The sooner the
mechanical engineering industry complies with the new regulations, the easier it will be to
bring its products onto the European market. Angst + Pfister
has already familiarized itself
with the coming changes. On
request, we can put together
component packages for our
customers that completely fulfill
the requirements of the new
Machinery Directive 2006/42/
EC.
The Machinery Directive 2006/42/EC
is intended to regulate the free movement of machinery within the EU with
greater clarity than the previous directive. At the same time, it serves to protect health and enhance safety for
machinery operators. Nevertheless, new
regulations of this sort are not exactly
designed to score popularity points
among the intended compliers. Instead,
they often give rise to a slew of difficulties such as the need for laborious
research, adjustment, documentation,
etc. The subject becomes even trickier
given the fact that failure to implement
the changes on time carries the risk of
costly product recalls, an EU-wide sales
ban or even criminal prosecution in
the event of personal injury.
Sit back and let Angst + Pfister take
care of things
What will change under the new
Machinery Directive 2006/42/EC?
The EU legislature has also taken a
tougher stance with regard to risk assessment. Although the previous directive required manufacturers to carry
out a risk assessment, the implementation of it was not clearly specified. With
the new regulations, the legislature
has set forth binding specifications regarding what a risk assessment must
entail. Angst + Pfister provides support
for its customers in carrying out required
risk assessments.
The new regulations simply replace
the previously valid ones and certainly
do not reinvent the wheel. However,
there are more differences than initially
expected. For example, the distinction
between the Machinery Directive 2006/
42/EC and special regulations such
as the pressure equipment directive, the
low-voltage directive or ATEX has been
changed.
There are also changes to the scope of
the new regulations. Whether it is the
inclusion of machinery parts, which are
soon to be known as “partly completed machinery”, in the directive requirements, or simply the new definition of
the term “machinery”, the list appears
endless. The amount of time and effort
involved for manufacturers or suppliers
of machinery parts to comply with the
new regulations increases in proportion
to the length of the list. However, the
good news is that, in the interest of our
clients, Angst + Pfister has already
paved the way for the introduction of
the new Machinery Directive 2006/
42/EC.
8
Even when a company is not directly
affected by the new regulations,
Angst + Pfister feels a responsibility
toward its customers in its role as a
supply partner. To put it succinctly,
a machine consists of a combination
of individual components. If just one of
those components is defective and
could pose a hazard under the new directive, the entire machine fails the test.
Customers who order from Angst + Pfister
today know that they can request
components that meet the requirements
of the new directive. This assurance
saves time and money, and no doubt
sets our customers’ minds at ease.

The acronym FAIR stands for one of the world’s biggest research projects in the field of basic physics.
The GSI Helmholtz Center for Heavy Ion Research has conceived a particle accelerator capable of generating antiproton and ion beams of unparalleled intensity and quality. In such a highly complex accelerator facility, every detail has to be perfect: plastic holders from Angst + Pfister help the photodiodes to
deliver ultra-precise measurement results and ensure that they never get rattled.

lies in building and operating particle accelerators. The FAIR project aims
to yield new insights into the structure
of matter and how the universe evolved
from the Big Bang to the present. The
accelerator facility should enable researchers to conduct an unprecedented
variety of experiments. GSI’s existing
particle accelerators will serve as preaccelerators for the new FAIR project
facility. Angst + Pfister contributes to the
functioning of the modern facility by
supplying specially developed finished
components made from a special highperformance plastic.

FAIR is an abbreviation for Facility for
Antiproton and Ion Research. The accelerator facility uses electrical and magnetic fields to bundle charged particles
such as ions and protons into a beam
and to accelerate them to high speeds.
The centerpiece of the facility is a
double-ring accelerator 1,100 meters in
circumference attached to a complex
system of cooler-storage rings and experiment stations. During the construction of the pre-accelerator complex,
which consists of a total of eight circular accelerators and two linear accelerators, the Angst + Pfister Group’s
know-how in the area of engineering
plastics technology was called upon. In
a unique cooperative project between
Angst + Pfister, the PANDA (= AntiProton ANnihilations at DArmstadt) research group and other partners since
March 2007, exclusive holders have
been designed for photodiode capsules that play a key role in reading
and measuring reaction products.
From the Big Bang to the present
Ions are atoms that have acquired a net
electric charge by gaining or losing
one or more electrons. The mission of
The project participants gradually closed
in on the final configuration of the photodiode holder, starting by selecting the
material, then continually adjusting the
prototype design and then moving to pilot batch production. This was not an
easy assignment, but the task was skillfully accomplished thanks to the experience and expertise of Angst + Pfister
and the project group headed by Dr.
Andrea Wilms. The specifications profile
for the component was very extensive.
The holders must stay dimensionally stable within a temperature range of
–25°C to +28°C. In addition to UV resistance, excellent resistance to doses
of radiation is vital. High dielectric
resistance should inhibit all conductivity,
and thermal conductivity should also
be as low as possible. APSOplast® PEEK

specifications and can survive long
service lifetimes without sustaining any
damage.

the GSI Helmholtz Center for Heavy
Ion Research is just one example of the
growing demand on the part of institutions and research organizations for
products and services from Angst + Pfister.
Alongside the flexible execution of
customers’ wishes, the development of
the photodiode holders highlights a
decisive advantage: the focused synthesis of materials, application and supplier expertise, all from under one roof.
APSOplast ® PEEK stands out for properties such as high stiffness and fatigue
strength. The use of the modified special compound containing titanium dioxide (TiO2) improves the excellent
property profile by additionally enhancing the reflectivity of the surfaces and
the UV resistance. By the way, the photodiode holders fabricated by
Angst + Pfister also meet the requirement
calling for high planarity. Angst + Pfister
injection-molds the parts in series production. This process ensures very tight
tolerances at points critical to proper
functioning. Aside from the cost advantages of large-series production, the
parts fabricated in a single batch are
all virtually identical.

members of this family of deformable
materials – such as PA, PP, PET, PEEK
and POM – are available as semifinished stock in a number of different
basic formats. In this context, one
particular service provided by the
Angst + Pfister Service Center is especially appreciated by customers: on
request, your plastic elements can be
directly cut to the right size, enabling
plates, round rods, tubes or profiles
to be put into use immediately without
any additional processing. Placing
orders for this valuable preliminary
work generally used to have to be done
by telephone or in writing, but today
the APSOparts® cut-to-size configurator
gives customers a new option for thermoplastic plates that is firmly integrated
in Angst + Pfister’s online shop.
Figure 1
Clear and comprehensible layout

Artner Handels GmbH specializes in making swimming pool
dreams come true. To protect
pools from the elements, the
Austria-based firm supplies a
wide array of pool coverings
ranging from weatherproof
tarpaulins and robust retractable flat covers to comfortable
pool enclosures. Quality always
stands in the foreground
at Artner Handels GmbH.
The company brought the
Angst + Pfister Group on board
for sealing and fastening
technology. High-grade
Angst + Pfister sealing profiles
guarantee optimum stability
and functionality thanks to
their customized design.
Those who value skill in building a
swimming pool are in the best of hands
with Pool Partner. Under this brand
name, Artner Handels GmbH has been
making all kinds of swimming-pool
wishes come true since 1997. Whether
circular, oval-shaped or rectangular,
on request the pools come with extra
features such as a beautifully designed
Plexiglas enclosure. To put the finishing
touches on its products, the pool experts at Artner Handels GmbH have
recently started to rely on first-class
special profiles from Angst + Pfister. The
plastic components make sure that
the enclosure panels sit securely, but
also ensure that the roofing elements
slide smoothly in the aluminum tracks.
2
Customized sealing profiles
Mutual know-how supplementation
shaped the collaboration between the
two companies right from the outset.
Artner was looking for a way to improve swimming pool enclosures from
a sealing technology standpoint and
found the perfect solution together with
Angst + Pfister. Since all conceivable
weather conditions needed to be taken
into account, EPDM was chosen as the
sealing material. Its resistance against
sunlight, ozone and other atmospheric
influences is outstanding, making
EPDM ideal for outdoor applications!
Since the Plexiglas panels are made
of acrylic, the sealing material must be
resistant to that as well. Normal EPDM
does not possess this property, so a
special acrylic-compatible formulation
was chosen. Then the right profile
shapes were selected. For the different
applications, Angst + Pfister developed
specially designed parts: U profiles
give Plexiglas panels the right support,
special brackets seal the enclosures
against the ground, and angled
connecting profiles form the junction
between the sliding elements. This
provides an optimal frame for the enclosure construction.
Successful balancing act
Over the course of their deployment,
pool enclosures and their components
must pass all kinds of toughness tests:
environmental influences such as snow,
rain, wind and dirt can afflict them and
can cause premature wear if the choice
of materials used is incorrect. The seals
from Angst + Pfister reliably meet all of
the requirements: the profiles are naturally resistant to ozone and all types
of weathering, but are also impervious
to contact with acrylic. The technically
ideal U profiles give the Plexiglas
panels enough maneuvering room for
thermal expansion, but at the same
time sit firmly enough to prevent slippage in the groove. Furthermore, an
especially high degree of mechanical
stability is necessary for assembly because the Plexiglas panels ultimately
need to slide longitudinally in the
groove. That adds up to a genuine balancing act that the custom-developed
profiles from Angst + Pfister perform
masterfully.
Intensive developmental work
The enormous advantages that the
seals from Angst + Pfister offer are
the fruit of intensive developmental
work. Unlike standard profiles, the
Angst + Pfister profiles are neither too
small nor too big, but are instead
tailored exactly to each specific application. This ensures in all cases that
the panels hold firm in the seals and do
not slip out of the grooves when thermal conditions change. A continual
exchange of ideas and know-how
between Angst + Pfister and Artner was
crucial right in the testing phase for
the profiles. This way, emerging difficulties could be quickly analyzed and
fixed.
Supply partner and service partner
in one
Although Angst + Pfister ultimately is
solely responsible for constructing the
components, involving customers in the
solutions devised by the Angst + Pfister
Group is an essential element. We
maintain close contact with our customers until the components and their products function perfectly, because there is
often optimization potential especially
in the startup phase for new models or
customized special components. But
our support does not end with the fabri-
cation of the component. Artner can
also rely on its supply partner for
support during the installation stage.
Angst + Pfister analyzes the feedback
from the installers onsite and, where
necessary, puts the finishing touches on
the molded components right on the
spot.
Advantageous price-performance
proposition
The first order was executed skillfully,
flexibly, rapidly, and to the complete
satisfaction of Artner. Follow-up orders
are now rolling in. From the swimming
pool builder’s standpoint, Angst + Pfister
is now its exclusive supply partner for
all sealing elements. The resulting bigger sales volume and administrative
savings enhance the price-performance
proposition. But the quality of the good

“Nugget”: In the fast lane
with bicycle brakes
The complete brake caliper in red is the Nugget version
available in stores.
The cross-sectioned brake caliper in gold shows the
installation position of the sealing rings.
Markus Weisl, Sales Engineer
“The excellent customer service from the staff at Angst + Pfister is the clincher for a lasting business
relationship,” says Marc Boriss, the proprietor of the Frank Industries company in Germany. This statement carries double weight because Mr. Boriss is speaking not just in his role as business proprietor,
but also as the designer of the brake system for which Angst + Pfister supplies a crucial component. This
brake system has sparked a sensation among users and experts. One can sense that Mr. Boriss’ creation
is dear to his heart not just in conversation with him, but also in the name of the product itself – the
Nugget. And the name says it all: the Nugget is truly as good as gold!
Marc Boriss doesn’t fit the stereotype of
a design engineer. He was once a racing cyclist and today is a passionate
downhill rider, and he greets visitors to
his website with the phrase “let’s rock.”
As a practitioner, he knows how important it is to be able to absolutely rely on
a vehicle’s brakes. Good brakes aren’t
a synonym for safety for nothing. The
Nugget is a brake system in a class of
its own. And lo and behold, it’s a
brake system for bicycles. All this ado
about bicycle brakes? Hold on there a
minute!
Bicycle brakes are highly complex
Bicycle brakes are much more complex
than automobile brakes, for example,
partly because the pistons – the Nugget
is a 4-piston brake system – must not
rest against the brake discs, but instead
must retract immediately after braking.
If the piston retraction malfunctions, the
pistons grind against the brake discs,
causing the brakes to squeal. In a car
that is not necessarily a problem, but a
cyclist, in contrast, might feel like he’s
suffering from tinnitus.
Seals are the crucial element for perfect piston retraction. On the one hand,
they must perform their main task: they
must seal off and prevent brake fluid
from leaking out. On the other hand,
they must not impede the retractability
of the pistons, which must have excel-
lent sliding ability. This is seemingly a
contradiction. Even the best brake design hinges on the seals. “The combination of brake and seal is the most important element,” Mr. Boriss
emphasizes.
Love at first sight
To develop the brake, it was therefore
necessary to find someone who could
design this linchpin of brake systems.
But who can you entrust your “baby”
to when such a crucial component is
at issue? Mr. Boriss came across
Angst + Pfister on a tip – and it was like
love at first sight. “A very friendly company,” says the design engineer about
his first encounter with Angst + Pfister.
Right from the outset of the collaboration, the partnership between
Angst + Pfister and Frank Industries was
marked by mutual trust and respect.
With enormous dedication, the developers at Angst + Pfister set about tackling this unusual assignment. A continual exchange of ideas between the
partners during the experimental stage
brought the team increasingly closer to
the solution. Alternatives were devised,
prototypes were tested onsite, and finally Angst + Pfister succeeded in constructing a seal whose design was so
perfect that the ingenuous Nugget idea
could now be suitably carried out.
Angst + Pfister brings additional
safety into play
What else must the seal do? Due to
the special design of the Nugget, its
heat absorption capacity increases by
around 50 % compared to conventional
brakes. If the brake, which is lightweight by the way despite the great
heat absorption ability, is to function
durably, i.e. if it is to be capable of absorbing a lot of braking energy over an
extended period, the seals must be
able to withstand temperatures up to
130ºC.
The thermal load capacity of the sealing material originally used – a special
EPDM compound – ranged in that
area. To add a safety buffer to that, the
material FKM is now being used on
recommendation by Angst + Pfister.
The deployment of this material, whose
thermal load capacity hovers in the
150ºC to 160ºC range, marks an
investment in additional safety.
The Nugget
The Nugget is also used in motorized racing.
A concerted solution in the
service of safety
The team-up of Frank Industries and
Angst + Pfister is a stroke of luck – not
just for both companies, but especially
also for all those who enjoy the benefits
of the Nugget. The close collaboration
gave birth to a brake system with an
exceptional degree of safety.
combination of design and seal. A
bicycle brake used for Formula Student
race cars or for 125cc Grand Prix
motorcycles – the Nugget is indeed
as good as gold.
The fact that the Nugget – which is actually a bicycle brake, mind you – is
now even being used in motorized racing is the result of a perfectly matched

Yves Riedo, Profit Center Leader
Getinge Produkt ions-GmbH
in Peiting, Germany, is a subsidiary of t he Getinge AB group
headquartered in Sweden.
The Getinge group is a leading
global manufacturer of equipment and turnkey systems for
healt hcare, t he pharmaceut ical
industry and laboratories.
Getinge Produkt ions-GmbH was
hunting for a sealing solution for
t he loading doors of its CM320
series of modular, versat ile, fully
automat ic mult ichamber washerdisinfectors. This out-of-t he-ordinary assignment was entrusted
to Angst + Pfister, which successfully solved t he problem by
means of a specially developed
AIRMATIC ® sealing system
t hat meets all of t he demanding
specificat ions.
One of t he toughest challenges in devising a sealing solut ion for such equipment is reliably sealing t he infeed opening, which in t his case gets shut wit h
t he assistance of a vert ical sliding door
wit h an insulat ing double glass pane.
The AIRMATIC ® sealing system is t he
ideal solut ion for t his case.
Simple and efficient
The AIRMATIC ® sealing system is especially recommendable for opening-andclosing applicat ions where a stat ic
seal needs to be formed at t he end of a
movement sequence. Being involved
as a partner already during t he designing of t he equipment is important in
t he search for t he right sealing system.
Angst + Pfister is a skilled partner and
consultant for all matters relat ing to
sealing technology.
The AIRMATIC ® sealing system is an
inflatable elastomeric profile t hat has
rolled-up reserve material tucked inside.
During t he sealing phase, t he profile is
inflated wit h compressed air t hat is applied t hrough a special air connect ion.
The compressed air forces t he tucked-in
reserve material to roll out and fill t he
sealing space wit hout any stretching of
t he material. The AIRMATIC ® sealing
system is t hus pract ically fat igue-proof.
The elastomer material and profile
geometry selected specifically for t he
deployment parameters enable t his
simple and efficient sealing technique
to be adapted to wit hstand t he toughest
operat ing condit ions and temperatures
up to +200°C.
The advantages of t he AIRMATIC ®
sealing system include:
• it easily compensates unevennesses
and deformat ions in t he sealing
space;
• t he seal exhibits no compression
set; consistent sealing force t hanks
to bolstering pressure;
• t he profile cross-sect ion is
self-retract ing;
• it is suitable for large sealing spaces;
• it provides a t ight seal;
• it features automat ic pressure control;
• it is easy to install;
• it makes it easier to design connect ions t hat need to be sealed.
How it works
The AIRMATIC ® sealing system is installed into a matching retainer groove t hat
runs around t he perimeter of t he infeed
opening of t he processing chamber and
seals axially against t he sliding door.
The seal must meet t he following requirements and specificat ions:
• it must seal t he processing chamber
against t he sliding doors;
• it must be capable of compensat ing
construct ion tolerances;
• it must be capable of bridging a
sealing space of 6 mm;
• t he material employed must comply
wit h FDA-177.2600 criteria and must
not be black;
• t he operat ing pressure must not
exceed 0.9 bar;
• replaceability must be guaranteed;
• resistance to hot air (t he drying cycle
involves a maximum temperature of
+100°C) as well as various detergents
and disinfectants is imperat ive.
The shape of t he seal and manufacturing process issues were crucial considerat ions in designing t he sealing system,
as was t he choice of material. The solut ion selected was a low-pressure rollout
seal t hat can be installed in a corresponding groove and inflated via a
special air connect ion. The sealing system meets all of t he desired requirements t hanks to its special cross-sect ion
geometry and t he assembly process,
which was precisely adapted to t he
specificat ions.

Cleaning process

When two companies complement each
other, the end-customer benefits
Manfred Rupflin, Sales Engineer, Angst + Pfister Germany
Andreas Staerr, Sales Engineer, LIAG® – Laeufer International AG
Hygiene is the top priority when
it comes to the production of
food and beverages, pharmaceuticals and cosmetic items.
And when it comes to cleaning
flow conduits in processing
plants and equipment even in
hard-to-reach inner locations,
the name of the solution is
“pigging technology”. With its
pigging systems, LIAG® –
Laeufer International AG in
Meersburg (Germany) makes
it possible to safely enjoy
industrially processed foods.
Angst + Pfister adds seasoning to
the soup in a sense by supplying a variety of sealing elements
and plastic components.
High-tech production processes in
the food-and-beverage industry make
sophisticated cleaning mechanisms
absolutely essential. Pigging technology is one of the most economical
and ecological ways to convey different
products through a pipeline while
cleaning the conduit at the same time.
When, for example, a certain type
of beverage is conveyed through pipelines, it leaves behind residues
that regularly have to be completely
removed. Consumers, after all, want
to enjoy their soft drinks and yogurt
drinks without any stale aftertastes.
Thorough flow conduit cleaning is all the
more important during production
changeovers. Pigging technology is indispensable especially when highly
viscous liquids such as oil are involved.
The pigging procedure ensures
maximum quality and process safety.
Two- and three-way arc valves and pigging valves from LIAG®
Fitted exactly to the application
Junctions of all types in such plants and
equipment represent especially critical points in the cleaning process. LIAG®
arc valves and LIAG® pigging valves
from Laeufer can ease these critical
points. The valves’ ability to smoothly
fulfill their tasks is substantially attributable to the harmonious interplay
between their individual components,
which is ensured in part by O-rings,
shutter materials and bearing sleeves
from Angst + Pfister. They are fitted exactly to the specific application at hand
and possess the corresponding required material properties. It goes without saying that they also comply with
FDA regulations.
Hygienic, low-maintenance and
operationally safe
Arc valves are predestined for viscous
and pasty media, but with pigging
valves as well, no product remains in
the valves during operation. The pig
continually engages the entire inner
pipe circumference. Depending on the
medium, the pig either moves through
the pipe along with the product flow or
is helped along by compressed air
or water. The pigging systems are designed to employ as few components
and wear parts as possible and are constructed in a way that avoids dead
pockets so that viscous liquids and pasty
matter can be completely removed
through cleaning and sterilization in
place (CIP/SIP).
Superior diversity
Angst + Pfister supplies Laeufer with Orings made from a wide range of
different materials. Ethylene propylene
diene monomer rubber (EPDM), for
example, features good resistance
against oxygen, ozone and thermal
degradation. Fluorocarbon rubbers
(FPM) are even better with regard to
the aforementioned properties and
are additionally extremely flame-resistant. All of the O-rings produced from
LIAG® pigging valve
these material compounds are exceptionally chemical-resistant, which makes
them interesting for the chemical industry and thus as components for the
pigging valves and arc valves manufactured by Laeufer. Angst + Pfister stocks
nearly 10,000 different O-rings in
its product assortment, including even
high-performance HITEC® O-rings in
a range of different qualities and compliance certifications. That’s especially
important from Laeufer’s perspective
because the company often needs a
wide array of different components only
in small quantities but at short notice.
In addition to offering a variety of country-specific compliance certifications,
Angst + Pfister also continually ensures
full product traceability.
Continually high quality
For its valves, fittings and pigging systems, Laeufer occasionally requires
special elements that are suitable, for
example, for contact with a specific
substance or for deployment at particularly high or low temperatures. At
Laeufer and Angst + Pfister alike, continual development and expansion
of the product offering is a never-ending
process. Angst + Pfister proactively
informs Laeufer about new items in its
product range that could potentially
be useful to the company. When proven and innovative solutions complement each other perfectly, the benefits
are ultimately reaped by the users
of Laeufer’s products, who profit from
a constant high level of quality.
Dependable and fast
For Laeufer International AG sales
engineer Andreas Staerr, Angst + Pfister
is a trusty supplier not just with regard
to O-rings: “I value Angst + Pfister’s expertise because we are in very good
hands with the company both in terms
of products and support service.”
And Laeufer considers it a big plus that
its longstanding supply partner fulfills
customer wishes not just reliably, but
also quickly. If an urgent need for a specific plastic part suddenly arises, one
phone call is generally all it takes to obtain it, oftentimes with next-day delivery.

Green light for green
NORMATEC® FKM O-rings
Spray-Matic 10 SP stainless steel pressure sprayer
Hugo Keller, Senior Engineer
It is not Angst + Pfister’s style to be satisfied with just making the grade. Always intent on creating
advantages for our partners, Angst + Pfister continually seeks out new solutions to optimize benefits for
customers. And that is exactly what we have also done with NORMATEC® FKM O-rings. The fluoroelastomer seals have excellent material properties and perform their task magnificently in their designated
application areas. But Angst + Pfister discovered a way to improve them: the seals used to be supplied
only in the color black, but now they are also available in green. The FKM O-rings are thus visually
easy to tell apart from conventional O-rings, making them much easier to handle, for instance in
assembly operations.
For years Angst+Pfister has been working together with Birchmeier Sprühtechnik AG as a supply partner. In Stetten,
Switzerland, Birchmeier Sprühtechnik
AG manufactures high-grade spraying
and foaming devices that enjoy a firstrate international reputation. Birchmeier Sprühtechnik AG exports more than
60% of its production volume and supplies its products to more than 40 coun-
tries. The company boasts a market
share of up to 90% in Switzerland. It
employs only the finest components in
order to guarantee enduring troublefree operation of its spraying and
foaming equipment. Angst + Pfister supplies Birchmeier Sprühtechnik AG with
a lineup of components that includes
NORMATEC® FKM O-rings.
A textbook application for
NORMATEC® FKM O-rings
The NORMATEC® FKM O-rings are
used as static or semi-dynamic seals in
the hose fittings, hand valves, filler
caps and sealing lids of Birchmeier
spraying equipment. The liquids used
in the sprayers are often aggressive.
The O-rings must withstand diluted acids, alkalis and solvents, and they must
provide a perfect seal over a long operational lifetime – a job tailor-made
for NORMATEC® FKM O-rings.
But there was one minor blemish: on
the assembly line and in replacement
parts service, the black NORMATEC®
FKM O-rings were hard to tell apart
from their likewise black “O-ring
colleagues” made from conventional
materials. To make it easier to differentiate between them, the seemingly
simplest and most effective solution at
first glance was to use colored FKM
O-rings.
Cautious innovation
Birchmeier Sprühtechnik AG wasn’t the
only company that requested the green
O-rings from Angst + Pfister; other customers were also interested. Out of
a sense of responsibility toward our
customers, Angst+Pfister subjected the
seals to a thorough examination and
subsequently decided to resist the temptation to simply add the green O-rings
to our product assortment, for two
good reasons.
In critical deployment areas like the
ones in which Birchmeier sprayers are
also used, the “interior life” of the
O-rings is a crucial determinant of their
enduring operational safety and dependability. The colored O-rings fell
well short of the black ones in terms of
their performance, mainly with regard
to their chemical resistance and compression set. Persuaded by this forceful argument, the customers decided
to continue using black FKM O-rings.
Meanwhile, Angst + Pfister closely monitored advancements on the material
development front.
Innovations in material engineering
have recently closed the small but critical performance gap between green
and black O-rings. Carbon black filler
is replaced by a light-colored additive,
making it possible to dye the O-ring
material. The green-colored modern
FKM materials can now confidently
compete with the original FKM material.
Green NORMATEC® FKM O-rings from Angst + Pfister are
employed in Birchmeier spraying equipment.
Angst + Pfister adds color to its
O-ring assortment
In view of the excellent properties of
the newly developed generation of
green O-rings, Angst + Pfister has now
given them the green light and has
added them to its standard product
range. The now high-grade elastomer
features excellent resistance to chemicals and a low compression set. Its mechanical properties are also outstanding. A high standard of quality coupled
with off-the-shelf product availability
and a very good value proposition
round out the green O-rings’ impressive
performance.
Angst + Pfister takes responsibility
toward its customers
Creativity and openness to innovation are a standard routine at the
Angst + Pfister Group. At the same time,
we are aware of our great responsibility toward our customers, and we
therefore give innovations the green
light only when we can justify that
to our partners.
NORMATEC® FKM NT 80.7/70
green O-ring seals feature the
following material properties:
• Color: green, similar to RAL 6021
• Hardness: 70 +/– 5 IRHD
• Operating temperature range:
–20°C to +200°C
• Short-term operating temperature:
up to +230°C
• Media resistance: generally
good resistance to chemicals;
resistance to oils, fuels, hydraulic
fluids, aliphatic hydrocarbons,
hardly inflammable fluids, acids
and alkalis, pesticides, detergents
NORMATEC® FKM NT 80.7/70
green O-rings and HITEC® precision
O-rings are both employed as components in the high-quality products
manufactured by Birchmeier Sprühtechnik AG. The optimum choice of
material ensures excellent operational dependability of the spraying
equipment and very long overhaul
intervals.
Easy differentiation between FKM
O-rings and those made of conventional materials is very important not just
to Birchmeier Sprühtechnik AG, but
to many other customers as well. We
would be glad to talk to you about our
HITEC® and NORMATEC® precision
O-rings. Contact us for a technical

Tradition meets innovation –
a perfect symbiosis
Wilhelm Veenstra, Sales Engineer
Germany-based UP-Schweisstechnik-Kelkheim GmbH manufactures high-grade arc welding equipment. The company traditionally focuses on submerged arc welding, an established arc welding process. But tradition isn’t the only road that UP-Schweisstechnik-Kelkheim GmbH follows. The company
also focuses on innovation out of the conviction that “combining our proven techniques with modern
technologies will continue to guarantee an optimal solution for your welding tasks.” One example
of such innovation is the suction hose from Angst + Pfister that vivifies the link between tradition and
modernity.
It’s not always major seminal inventions
that optimize established processes.
Angst + Pfister has succeeded in altering
a component of the welding equipment
manufactured by UP-SchweisstechnikKelkheim GmbH to give its customers
a competitive edge: Angst + Pfister has
replaced the hoses previously used
to suction up excess welding flux with
one that offers advantages over
conventional hoses. The APSOfluid®
UNIFLEX™ suction hose stands out
for properties that can described as
trendsetting.
Conventional suction hoses –
compromises with consequences
The unmelted flux on the slag that
forms in the submerged arc welding
process puts suction hoses to a tough
test in several respects. The hoses
must be very flexible. At the same time,
the residual flux has a temperature of
more than 100°C and is gritty, and
thus puts considerable strain on the interior surface of suction hoses. Ruggedness, high flexibility, temperature resistance and good mechanical resistance
to abrasive media – that’s the combination of properties you want.
With conventional suction hoses, compromises have to be tolerated with re-
Mobile submerged arc welding tractor unit, view of carriage
Tandem submerged arc welder, inner welding head
gard to desired performance under the
motto: “You can’t have everything all at
once.” It’s mainly the hitherto accepted
compromise between flexibility and
ruggedness that scores poorly. In order
to provide sufficient flexibility, the
hoses are corrugated inside and out.
That’s a clear disadvantage: the mechanical resilience suffers because
the corrugated interior surface reacts
sensitively to the abrasive residual flux.
The lifespan of the hoses thus shortens,
with all of the attendant undesired consequences such as reduced durability
of the welding equipment and thus
more frequent machine downtimes and
higher maintenance costs.
On top of that, Angst + Pfister offers yet
another advantage: there are no minimum order requirements. We supply
even tiny order volumes and special
lengths of APSOfluid® UNIFLEX™ suction hoses at the best pricing conditions. The excellent value proposition
of APSOfluid® UNIFLEX™ suction hoses
is impressive indeed.
A detail that makes a difference
Submerged arc circumferential welding of containers
APSOfluid® UNIFLEX™ –
sleekly suctioned up!
UP-Schweisstechnik-Kelkheim GmbH
approached Angst + Pfister with a mission: to find a solution that brings all
of the desired properties of a suction
hose together all at once without
any compromises. Through real-time
prototype testing and subsequent clearance by the persons in charge at
UP-Schweisstechnik-Kelkheim GmbH,
Angst + Pfister succeeded in winning
the company over with the APSOfluid®
UNIFLEX™ suction hose.
The APSOfluid® UNIFLEX™ hose is
extremely rugged, it withstands the temperatures of the heated residual flux
and – what’s truly exceptional – it has
a smooth interior surface in contrast
to conventional hoses. This enabled
Angst + Pfister to kill two birds with one
stone: the APSOfluid® UNIFLEX™ hose
is flexible, making very tight bending
radii possible, and at the same time it
is much less sensitive to employed
welding additives.
Service through logistics
The APSOfluid® UNIFLEX™ suction hose
on its own already creates an advantage for UP-Schweisstechnik-Kelkheim
GmbH, but Angst + Pfister has even
more to offer. A sophisticated logistics
setup enables Angst + Pfister to ensure
high product availability for the entire
range of APSOfluid® UNIFLEX™ hoses,
thus minimizing delivery times. This
eliminates expensive inventory carrying
costs for the customer.
The solution that Angst + Pfister devised
together with UP-Schweisstechnik-Kelkheim GmbH demonstrates that even
seemingly small “side attractions”
present the potential to create added
value for partners. It also demonstrates
that established conventional processes
don’t have to be old-fashioned – it’s all
simply a matter of choosing the right
partner.
With creativity and commitment, new
paths can be forged where tradition
and modernity converge – a symbiosis
in service of customers.

APSOdrive® solution transmits 200 tons of
pressing force
Fred van de Poll, Product Application Engineer
Press brakes are used to bend sheet steel and therefore have to generate relatively strong pressing
forces. A hydraulic drive is usually employed to achieve that. However, since hydraulic press brakes
cannot deliver the desired high precision, the Lochem, Netherlands-based Safan company decided
to replace the hydraulics with a servo-electronic drive system. The fruit of that decision is the E-Brake
press brake, which is available in several different models. The largest E-Brake model can transmit
a whopping 200 tons of pressing force with amazing accuracy and low energy consumption thanks to
the utilization of a flat drive belt.
As a manufacturer of sheet metal
working machinery, Safan plays a leading role in the field of press brakes
and shears for thin sheet metal. Safan
has mainly specialized in developing electronic applications. The groundbreaking servo-electronic E-Brake
press brake is one of the company’s
specialty products.
Electromechanics instead of hydraulics
The groundbreaking E-Brake press brake manufactured by
Safan consists of two servomotors, a pulley system and a
special flat drive belt.
The E-Brake’s servo-electronic drive consists of two servomotors, a pulley system and a special flat drive belt. A socalled O frame is additionally built
in. The advantage of this closed frame
is that it ensures that the press brake’s
bending tool follows the predetermined
line without any deviations, even under stress. The even force distribution
made possible by the pulley system,
in combination with the aforementioned
frame, produces metal-bending precision that exceeds the accuracy obtained
with a hydraulic press brake. Actual
practical employment of the machinery
has revealed that the E-Brake can
shorten production cycle times by 30%
and can reduce energy usage by 50%.
After a good ten years under development, an E-Brake for pressing forces
of up to 200 tons and workpiece lengths
of up to 4 meters is now available.
The pulley system utilizes toothed belts.
Since Angst + Pfister for years had
already been supplying Safan with
toothed belts for a number of different machines, it was only logical for
Safan to consult with Angst + Pfister
during the development of the E-Brake
as well. It quickly became clear that
26
Angst + Pfister’s standard product range
did not contain any toothed belts
that could be used to produce the desired pressing force.
was increased from 50 mm to 100 mm,
doubling the pressing force from
25,000 N to 50,000 N and raising the
permissible tensile force to 30,000 N.
No effort too big
Comprehensive range of standard belts
So Angst + Pfister moved heaven and
earth to find a customized solution
for this application. A flat drive belt
from the standard Breco product range
was selected as the basis for devising
a much stronger drive belt. This BRECO®
polyurethane drive belt has a special
feature: tiny steel wires embedded in
the polyurethane. These steel wires
give the flat drive belt sufficient tensile
strength. To enhance the drive belt’s
power density even further, a special
thicker steel tension member was used
and the thickness of a 50-mm-wide
standard belt was increased from 2 mm
to 2.5 mm.
In addition to supplying specially developed toothed drive belts, Angst + Pfister
also stocks a comprehensive range
of standard polyurethane and neoprene
toothed belts. These in combination
with the accompanying pulleys and other accessories make innovative solutions possible. Angst + Pfister would be
glad to help you make the right selection from our extensive product assortment.
After a battery of tests, the drive belt
was okayed for the smallest E-Brake
model. The permissible load rating was
11,200 N, which is sufficient for a
press brake with 50 tons of pressing
force. For the press brake with 200
tons of pressing force that was developed afterwards, the drive belt was
again readapted: the width of the belt

No cold coffee – Angst + Pfister round
buffers in professional coffee machines
Walter Oertli, Senior Engineer
Custom-fabricated round buffers from Angst + Pfister for the
Cafina ALPHA models.
Specifications checklist:
Together with the engineers at Cafina,
Angst + Pfister’s antivibration technology experts employed a sophisticated
testing procedure to ascertain the
demands that the newest generation
of coffee machines – the Cafina ALPHA
line – places on its components. The
“heart” of the coffee machines is their
brewing chamber. There, freshly ground
coffee is compressed by a piston, then
highly pressurized hot water is forced
through the coffee grounds and the
brewed coffee flows directly into the
cups. This piston is driven by a stepper
motor that is mounted on four small
round buffers.
The round buffers serve to elastically
suspend the drive motor and to suppress its vibrations so that the coffee
machines run as quietly and vibrationless as possible. At an operating temperature of 60°C and peak temperatures of up to 80°C, resistance to heat
is the main challenge that all coffeemachine components must meet. In the
case of the Cafina ALPHA line, the
round buffers must guarantee proper
functioning even at high temperatures.
…require well-thought-out solutions...
In a special series of tests, the engineers at Angst + Pfister documented how
the spring characteristics of the rubbermetal buffers change at high temperatures. An exactly calibrated composite
mixture of EPDM and CR emerged as
the ideal material combination. EPDM
stands for ethylene propylene diene
M-class rubber and CR stands for chloroprene rubber, which is also called
neoprene. EPDM is well known for its
excellent thermal resistance properties.
The test results were immediately put
into practice: today Angst + Pfister supplies the Cafina company with customfabricated round buffers that are
optimally adapted to the Cafina ALPHA
line of coffee machines.

...and reliable quality assurance
To guarantee maximum long-term quality, Angst + Pfister rigorously inspects
and tests the finished round buffers before they are shipped to the customer.
Even in the area of quality measurement,
Angst + Pfister is setting new standards:
instead of simply measuring hardness
using the Shore method, our engineers
have developed a new system that
enables the load deflection curves for
compressive and shearing strains on
Angst + Pfister round buffers to likewise
flow into the hardness rating. Spring
characteristics are thus distinctly verifiable even for tiny workpieces. A
special clamping device was specifically constructed to record these load
deflection curves.

The aroma of freshly ground coffee
beans and the enticing sound of foaming milk are an intrinsic part of the
ambience of a cozy afternoon in a coffeehouse – the rumbling of a poorly
insulated motor or the stench of overheated rubber definitely are not. In
close collaboration with the manufacturer Cafina, Angst + Pfister thus developed the ideal round buffers for installation in large coffee machines for
the restaurant industry. The fully automatic Cafina coffee makers can be
found in many popular cafés and in major restaurant chains and hotels like
the famous Kempinski in St. Moritz,
Switzerland.
The new Cafina ALPHA puts coffee enjoyment at center stage.

Shear force
Everyday we encounter round buffers virtually everywhere, but they usually go unnoticed. Round buffers
from Angst + Pfister work behind the scenes to ensure smooth functioning of a vast array of different
machines by suppressing undesired vibrations and noise. But be careful: not every round buffer is suitable
for every extreme condition! To avoid a rude awakening, the experts at Angst + Pfister help you in the
early planning phase to find the ideal round buffer for your application. Angst + Pfister, for example, has
developed a heat-resistant round buffer capable of withstanding the severest of strains for Cafina, the
renowned Swiss manufacturer of professional coffee machines for the restaurant industry.

Quality down to the tiniest detail
Complex processes can only function
smoothly when all individual components are 100% reliable. We therefore
take our customers’ wishes very seriously and work together with them to
devise the optimum solution for each
specific application. Drawing on our
close collaboration with manufacturers
like Cafina and the resulting empirical
experience, Angst + Pfister has developed a specifications checklist for customized antivibration technology
components. With this checklist, a little
information is all we need to fabricate
exactly suited components for you.
Using this specifications checklist, we
can rapidly and reliably analyze which
industrial components are suitable
for your specific application. Our engineers define the precise requirements
for all materials, the maximum allowable
strains, potentially necessary treatments
– for surface protection for example –,
as well as the requisite spring characteristics, dimension measurements and
tolerances for all components. We prepare an exact fabrication drawing
in coordination with manufacturers and
customers, and we provide you with
test documents as well as shipping and
installation instructions.

PWA contactless angle sensors
Ultra-miniature Ø 5mm MES-3P & MES-3PST encoders for robotics and medicine
The new line of PWA contactless angle
sensors with electrical angle up to 360°
and 12 bit resolution has been designed
as a sturdy solution for industrial as well
as in mobile applications.
The new MES-3P series of ultra-miniature
encoder with a diameter of only 5 mm
and a weight of only 5 g is offered
by PEWATRON as the world’s smallest
encoder.
The line currently consists of 3 series, all
of which feature a ratiometric 5 V output:
• PWA1 series: with integrated magnet
and return spring;
• PWA8 series: with separate magnet
(at request with magnet support);
• PWA9 series: like PWA8, but with
2 independent redundant outputs for
fault detection in the measurement system. Optionally available with PWM
output.
It is suited for all fields of precision
mechanics, robotics and medical engineering where precise and fast angular
movements need to be detected in minimum space conditions.
The PWA8 and PWA9 series are characterized by a high insensitivity to mechanical tolerances (magnet offset) and an air
gap of up to 5.5 mm. Owing to the secure attachment by means of metal lugs,
a high temperature range of –40°C to
+85°C (optionally +125°C) and protection class IP67/IP68, the PWA line is
ideally suited for use in rough environments.
The output characteristics are pre-programmed, but can also be customized
optionally. This enables individual fine
adjustment of each sensor to the respective environment, for example to compensate mechanical tolerances.
The electrical connection is possible via
strands or IP67-rated connectors.
Axial as well as radial cable outputs are
available:
• MES-3P with an axial cable output,
dimensions Ø 5 mm x 12.6 mm;
• MES-3PST with a radial cable output,
dimensions Ø 6 mm x 11.6 mm.
Samples are now available.
The encoders offer 64 or 1,024 pulses/
revolution, respectively with A, B and Z
output signals, with maximum rotation
speeds of 6,000 rpm.
smartALERT – the talking gas detector
PEWATRON introduces the new gas detector smartALERT, which was developed
by smartGAS especially for use in fixedposition monitoring of ambient air for
combustible or harmful gases according
to the binding guidelines of DIN EN
50194 (VDE 0400 part 30-1).
The technological prerequisites for doing
this are provided by the smartMODUL
measuring system, which also makes the
smartALERT affordable for domestic use.
Due to its integrated infrared sensors,
smartALERT even detects extremely low
gas concentrations. smartALERT was developed for installation in private households, commercial enterprises, biogas
plants, commercial kitchens and public
buildings.
The integrated voice informs the user
about the ongoing dangerous situation
– much like a car navigation device –
and provides precise conduct instructions. This extraordinary feature makes
searching for an instruction manual unnecessary in the event of an emergency
and therefore saves important time.
The integrated manipulation surveillance
makes incorrect handling impossible.
The device is mounted on the wall and is
directly connected to a 230 VAC outlet,
or if desired also to 24 VDC.
On the basis of the infrared absorption
method, it is able to securely detect for
more than 10 years without maintenance.
smartALERT is equipped with a patented
and unique voice synthesizer. The verbal
instructions correspond to the respective
risk level and have a demonstrably deescalating effect in the case of an emergency.
