Precision mold manufacturing requires high quality, not only high machining accuracy, but also good surface quality. Generally speaking, the manufacturing tolerance of the working part of the mold should be controlled within ±0.011mm, and some even require it to be in the micron range. The surface defect requirements after the mold are processed are very strict, and the surface roughness of the working part is required to be Ra <0.8 um.
