Transfer moulds - Import export

In the area of elastomer technology, the Zimmer Group uses the most modern production processes to manufacture sophisticated workpieces from elastomers. In addition to the transfer molding process, in which the elastomer is placed in a mold, pressed into shape with a die and vulcanized under pressure and heat, we also use the injection transfer molding process. Here, the starting materials are pressed into the mold on an injection molding machine and vulcanize out there. With these two processes, we process a wide range of elastomers such as NBR, silicone, EPDM, FPM or polyurethane. In terms of quantities as well as dimensions, the sky's the limit, because we can manufacture almost any quantity required, from special solutions in quantities of one to medium-sized small batches and large series of more than 10,000 units.

Fiber-reinforced composites are in demand in all high-end industries in which light weight and at the same time high durability under dynamic load ensure competitive advantages Efficient and reliable press technology for fibre composite plants Whether glass fibre reinforced plastic (GRP) or carbon fibre reinforced plastic (CFRP): The valuable material is mainly used in application fields where weight reduction, fuel consumption,anti-corrosion characteristics and other stress resistency feauters are in focus. The name Siempelkamp also stands for solid and precise technologies in these presses and handling systems as well as for high flexibility due to its suitability for all composite applications such as sheet molding compounds with glass or carbon fibers (SMC), prepreg compression molding with short, long or continuous fibers (PCM), resin transfer molding (RTM), and thermoplastic forming.

Coatings made of PFA and PVDF fluorine-based thermoplastics provide safe protection against corrosion even on exposure to aggressive media. Because its molecular structure resembles that of PTFE, PFA is almost universally resistant to chemicals. Other special features of PFA linings are their wide range of operating temperatures and easy cleaning due to the material’s non-adhesive nature. In many applications, this makes it possible to replace stainless steel with a raw material which is not only much more economical but also easier to process. Because coatings are applied in a thermoplastic transfer-moulding process, it is necessary to account for certain design aspects which our team will gladly discuss with you in advance.
