Plastic mold production of general machinery products in common, and also that its particularity. Compared with the general machinery manufacturing, mold manufacturing is generally difficult, especially precision molds. As a special technical equipment, mold production and process are the characteristics of the following aspects.

1. Precision mold manufacturing, high quality requirements, not only requires high precision, but also processing good surface quality. In general, working part mold manufacturing tolerances should be controlled within ± 0.011mm, and some even require within micron range, surface defects after tooling requirements are very strict, and the surface of the working portion of the roughness Ra
