Kastaş R&D work focuses on developing sealing technologies. The strategic plan targets adding at least one original product to standard product families each year; in addition, nearly 500 new designs a year are made for customer needs, and special, scheduled product groups are developed. Product and mold design is done with 3D design software, prototypes are built, and new designs are checked with finite-element analysis before physical testing. Moldex3D and Digimat are used to simulate material and fibre flow inside the injection mold. The Test Center, established in 2006, runs hydraulic and pneumatic piston and rod tests, wiper and bearing tests, and high-pressure, low-temperature and high-temperature tests. Elastomer materials are developed in-house; polymer materials are developed through international cooperation and certified in the laboratory and by international test bodies.
