Thermoplastic Foam Injection Molding
At Wiesauplast, thermoplastic foam injection molding is only used for manufacturing complex technical function parts. Charging gas by means of a physical blowing agent in the manufacturing process saves weight by forming a cell structure. The expanding gas in the tool acts like post-pressure on the fused material. This reduces the number of sink marks and achieves uniform material shrinkage, regardless of flow paths, and better dimensional accuracy.
