Enabling of sandwich-injection moulding by upgrading
of single or multicomponent injection moulding
machines
Summary
A small German engineering company has developed modules to retrofit a broad range of injection
moulding machines to enable sandwich-injection moulding processes. The SME is searching for
industrial partners and research institutions for technical cooperation agreement, commercial
agreement with technical assistance or license agreement to implement the modules jointly and to
share their knowhow regarding the development and production of sandwich-injection moulded
parts.

Description
The small German engineering company is developing
supplementary modules for injection moulding machines and offering support to exploit them
with the matching technologies, the matching materials and the matching product structures.
They offer modules to retrofit a broad range of single- and multi-component injection moulding
machines to enable sandwich-injection moulding processes.
With sandwich-injection moulding (also called co-injection), plastic parts with extended
properties and advantages can be produced, i.e.
• material cost savings with regrind as core material,
• weight reduction by using foamed polymers in the core,
• increase in strength by fibre reinforced polymers,
• colour effects by different coloured polymers.
In one single process two different plastic materials are injected successively (and also shot
time simultaneously) into the injection mould as skin material and core material.
The different characteristics of the skin and the core material and their combination provide a
broad variety of features of the resulting multi-functional mouldings.
Sandwich-injection moulding is currently not widespread because it is commonly connected to
2-component machines, which are by 1,2-times to 1,6-times more expensive than standard
machines and the moulds must have a cold runner in the most cases.
The developed solution consists of a variety of add-on modules like 2-component sandwich
nozzles and intermediate plates and their selection/design as well as of the provided knowhow
of the company to select the raw materials and to configure the moulding process to reach the
desired product features.

The SME is searching for industrial partners and research institutions for technical cooperation
agreement, commercial agreement with technical assistance or license agreement to implement
the modules jointly and to share their knowhow regarding the development and production of
sandwich-injection moulded parts.
The searched partners should be active in the area of plastic parts production, the production of
moulding machines or components.
The actual type of the agreement depends on the type and the needs of the partner for support.
Advantages and Innovations
The developed solution opens the way for almost all standard and multicomponent injection
moulding machines to execute sandwich-injection moulding processes with very low material
efforts for the upgrade.
This enables
• plastic parts production in a very cost saving and environmentally friendly way regarding
material consumption (i.e. regrind as core material),
• weight reduction of the parts by using foamed polymers in the core,
• increase in strength by fibre reinforced polymers,
• colour effects by different coloured polymers.
Depending on the type of the parts other effects, basing on possible new product features, are
expected.

Partner Sought
Type and Role of Partner Sought
Industrial partners, producing plastic parts by injection moulding, are sought for upgrading their
machines, joint development of sandwich-injection moulded parts.
Industrial partners, producing injection moulding machines or core parts (tools), are sought for
upgrading their portfolio and retrofit their customer’s machines.
Research partners, developing new injection moulding technologies respectively parts, are
sought for qualifying their technologies/parts.
The type of cooperation depends on the R&D-level of the partner and on the necessary R&Dinvolvement of the SME.
