For such applications of heavily loaded structural components reinforced thermoplastic materials are predominantly used, mostly filled with glass fiber.
This yields in high stiffness which is why the products must be manufactured with good precision as they must not be forced into position while assembling. Additional problems are caused due to warpage after moulding as a result of orthotropic material properties and different shrinkage factors in the fiber orientation directions and perpendicular to it.
- movement of assembly holes out of tolerance fields
- uneven sealing surface
- cilindricity on the mounting spot for oil filter cap
- elimination of risks in the industrialisation phase
- less tool trials - shorter time-to-market and lower industrialisation costs
- focusing on product's functionality by outsourcing the technological problem solving to an experienced partner
- optimal process - longer tool life and shorter production cycles
