Let the plastic mold factory tell you the basic knowledge of plastic molds

Plastic molds are generally divided into injection molding/extrusion/compression molding/blow molding types

But in fact, most people discussed generally refer to injection molds, and injection molds with smaller weights are also difficult to make.

Compared with the requirements of plastic mold materials, the main performances of plastic molds are:

1. Polishing: For example, auto lamp molds and optical lens molds require high polishability

2. Toughness: Plastic molds such as bumper molds have high requirements for the toughness of mold steel because the mold itself is large.

3. Corrosion resistance: Some plastic particles are inherently corrosive, and stainless steel is required for corrosion resistance requirements.
