Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the mold parts, the smaller the wear amount and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material. The toughness of the mold mainly

Polyoxymethylene is divided into two types: homopolymerization and copolymerization. Copolymer has good short-term strength while homopolymer has good flexibility. The copolymer has a softening point 10°C higher than that of homopolymer, has a high thermal deformation temperature under load, good thermal stability, and a wide molding temperature range. Commonly used in industry is acetal copolymer.
