There are many kinds of materials used in the injection molding process, and there are big differences in their quality. Mainly in the appearance of manufactured products, comfort, feel, lightness, softness, insulation, breathability, etc.; its physical performance indicators also differ, such as the maximum tensile strength, elongation, abrasion resistance, resistance to moisture and the degree of chemical corrosion resistance.
According to the material used in the injection process, the injection process can be divided into injection molding, rubber injection, rubber and plastic and injection and so on three kinds.
