1. PC Material (Polycarbonate) 1. PC Material (Polycarbonate) Features ①Amorphous plastic, no obvious melting point, glass transition temperature 140℃~150℃, melting temperature 215℃~225℃, molding temperature 250℃~320℃. ② It has high viscosity and is sensitive to temperature. It has good thermal stability within the normal processing temperature range. It basically does not decompose when staying at 300℃ for

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 future development direction of injection molds: 1: High precisionWhether the dimensional accuracy can be achieved is the most important factor in manufacturing high-precision, high-quality, high-tech products. Japan and Germany were the best in the past. With decades of continuous learning and innovation, a large number of companies specializing in high-precision mold manufacturing have emerged

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
