WebThis leads to cracks in parts during long-term use. The shrinkage of molded plastic parts can be as much as 20% by volume when measured at the processing and ambient temperature. This volume contraction of polymers often leads to wrapped parts and dimension differences. These changes occur between manufactured parts and the mold. WebTPE injection moulding and TPU injection moulding is a popular material of choice. Polyurethane coatings are used for their solvent degradation resistance and impact …
