UNIVERSAL HOTMELT SYSTEM SOLUTION New Slot Die System Solution for all hotmelt applications REQUIREMENTS FOR DEFECT-FREE HOTMELT COATINGS APPLICATION AREAS Defect-free hotmelt coatings on different substrates do not only require application devices which work reliably and which are easy to operate, but in addition place great demands on the homogenous heating of melting systems, the pulsation-free mass supply, the easy control of layer thicknesses, etc., in order to ensure a quick and very even application of the hotmelt. Inhomogeneities or coating defects caused by an imprecise mass supply or by crackings in the melting process due to temperature peaks have to be avoided. Complete FMP System for Hotmelt Coatings with FMP Slot Die Hotmelt-coatings are used in many sectors of industry to apply hotmelt adhesive systems on substrates of different materials. Typical application areas are: Packaging industry Printing industry Hygiene industry Wood and construction industry Textile industry, etc. Due to the high interest in a flexible, universally applicable application system for different hotmelt systems, the process and construction engineers at FMP have developed a software-based complete hotmelt adhesive system for the extensive or structured application with a slot die. In contrast to the current state of the art, different hotmelt adhesives can be processed for the first time with one die only without quality losses. However, currently available hotmelt die systems generally have to be manufactured for individual applications or have to be adjusted in a time-consuming process. The optimal hotmelt application method and the specification of the hotmelt system can be chosen either based on past experiences, by trial and error (empirics) or based on analytical calculations. By means of modern, theoretical design methods, valuable time, machine and employee resources can be saved considerably. Today, the design methods are developed so well, that, based on the calculation results, complete hotmelt systems and hotmelt application devices can be specified, constructed, manufactured and put into operation within a few days – guaranteeing the requested, optimal coating quality without any pilot tests. The reproducible, controllable interaction of all peripheral processes of a hotmelt coating has to be mastered in order to achieve high-quality and error-free film layers on substrates. Analogous to the application of watery or solvent based fluids, the FMP hotmelt coating is based on the knowledge on rheological properties of the hotmelt adhesive to be coated and the property of the substrate to be coated. Hereby, FMP TECHNOLOGY calculates the process of the hotmelt coating based on measurement results of the dynamic viscosity, the surface tension and the wetting. Based on the obtained results, the hotmelt system can be adjusted precisely so that optimal hotmelt layers can already be achieved after a few centimeters of coating distance. HOTMELT-COATING WITHOUT RISK COMPLETE SYSTEM OF FMP WITH HOTMELT DIE The innovative slot dies of FMP TECHNOLOGY GMBH do not only convince for hotmelt coatings but also in various sectors with the highest ease of operation, flexibility and a guaranteed lateral distribution precision of the layer which is to be applied. Due to the patented diffusers inside the die, the same FMP die can be used for various areas of application without having to be adjusted: Hotmelt coatings Coating of solvent and watery fluids Foil extrusion Mainly the die application device and the hotmelt adhesive mass supply have a significant influence on the quality of a hotmelt coating. The complete hotmelt system of FMP TECHNOLOGY GMBH, which consists of a heatable FMP hotmelt die, an intelligent melting and supply unit with integrated filter technology as well as heated supply hoses offers perfect prerequisites for a high-quality application of diverse hotmelts. Whether it is a low-viscosity nano coating or a high-viscosity adhesive application, the special distribution system of the FMP slot die, which is based on extensive CFDsimulations and practical coating experience, enables the application in almost all areas. FMP-Slot Die System Solution for the Integration into existing production facilities ONE FOR ALL – one complete system for all applications consequently describes the successful concept of FMP. Especially manufacturing companies or research-oriented work groups with a high number of different coating products (foils, labels, metal bands, plaster board, glass plates, adhesive tapes, paper, non-woven fabrics, textiles) as well as raw material manufacturer (adhesives, paints, lacquers, granulate, glue) make use of the complete system of FMP in order to cover all product areas with the universal FMP application system. Hotmelt coatings of partial possible with the FMP dies, too. webs are HOTMELT-COATING WITHOUT RISK ABOUT FMP TECHNOLOGY GMBH ADVANTAGES Users of the coating technology can produce diverse coating products which have different, often changing viscosities and mass flows (wet film thickness), with one die (“ONE FOR ALL”) without quality loss. In 2006, FMP TECHNOLOGY GMBH was founded as a spin-off of the Institute of Fluid Mechanics at the University of Erlangen. It has the aim to take up scientific developments, to develop them into novel, innovative products, - especially for the coating and drying technology – and to market them. A complete system ensures the intelligent and quick integration into existing laboratory and manufacturing systems. Up to now, coating application systems for the coating and impregnation of paper, textiles, non-woven fabrics, foils, glass, wood etc. as well as for the foil extrusion or the hotmelt coating had to be specially designed, selectively manufactured and put into operation with long, costly test series. FMP-software “Coating Window Suite” for the calculation of coating windows is the basis for the adjustment of machine parameters without lengthy and costly empirics. High flexibility for the production of diverse products. COATING WITHOUT RISK In contrast to this state of the art, FMP TECHNOLOGY GMBH developed a new, universally applicable slot die which can be used for the first time to produce various products. The lateral distribution accuracy of the layer to be applied is guaranteed without prior test series and with moneyback guarantee. Ultra precise, selective coating accuracies (±1%,±3%,or ±5% selectable) guaranteed. Minimisation of thermal die deformations due to the use of special steel. FMP System Solution including: + FMP-Hotmelt Die + Heating Elements & Controller Unit + intelligent melting and feeding unit + Filtration + heatable hoses FMP-Hotmelt Die, width 1.750 mm In 2010 FMP TECHNOLOGY GMBH was honored with the following awards: Gründerpreis Mittelfranken (Founder Award Central Franconia) Bayrischer Gründerpreis (Bavarian Founder Award) IHK- Gründerpreis (Founder Award from the German Chamber of Industry and Commerce) Federal Ministry of Commerce and Technology ABOUT FMP TECHNOLOGY GMBH FMP TECHNOLOGY GMBH was founded in 2006 as a spin off of the Department of Fluid Mechanics at the University of Erlangen with the aim of addressing and exploiting scientific and technical developments and of developing and marketing new and innovative products. In the four different business areas of FMP TECHNOLOGY GmbH, all based on the fluid mechanics, ground-breaking developments have been carried out, particularly in the field of coatings and fuel injection. In coating technology, one development of FMP TECHNOLOGY GMBH relates to an innovative coating die. In contrast to conventional coating dies, various fluids can for the first time be processed with only one coating die without any sacrifice in quality. Coating dies currently on the market, in contrast, must basically be designed for a specific coating fluid, which has, up till now, forced users to invest in numerous different coating dies.

With great effort, new and innovative pressure-wave-free injection systems that provide optimal droplet distribution during injection (the so-called spray) have been developed for engines. An injector being researched in a pilot project significantly reduces fuel consumption and also significantly lowers harmful emissions. The prototype for the new injection system should be ready by the end of 2010.
