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.

The close relationship between injection speed and product quality makes it a key parameter for injection molding. By determining the beginning, middle, and end of the filling speed segments, and achieving a smooth transition from one set point to another, a stable melt surface velocity can be ensured to create the desired molecular extraction and
1. Let’s Introduce What Is An Insert In Mold? Insert is a term for molds. In the mold, it specifically refers to the mould accessories used to be embedded in the mold core. Inserts can be square, round, or sheet-shaped. Like all mold accessories, the requirements for precision are also very high. Generally, there is no
