Precision injection molding and ordinary injection molding

Ordinary molding does not require high dimensional accuracy for injection molded parts, while the appearance requirements for injection molded parts are relatively higher. It does not require high-precision injection molding machines or specially specified materials, and commonly used thermoplastic plastics can be used for production. This is also one of the reasons why they are widely used in the modern plastic industry.
Compared to ordinary injection molding, precision injection molding has high dimensional accuracy and tolerance requirements for injection molded parts, as well as material requirements. Generally, POM/POM=CF (carbon fiber), PNM=GF (glass fiber), PA/FRPA66 (reinforced PA)/PC, etc. are used.
Precision injection molding should achieve the following points:
1. The material of the mold should be good, with sufficient rigidity, high dimensional accuracy of the cavity and positioning accuracy between the molds, and low surface roughness.
2. Precision injection molding machines should be used.
3. We need to use precision forming technology.
4. Choose materials suitable for precision injection molding processes.
The above is an introduction to the key points of precision injection molding and ordinary injection molding, hoping to be helpful to everyone.
