Plastic mold manufacturing can generally be divided into 5 major steps. Xiaobai hurried to learn. 

1) Analysis of plastic parts In the mold design, the plastic mold engineer should fully analyze and study whether the plastic parts meet the mold opening requirements, including discussing the geometric shape, dimensional accuracy and appearance requirements of the product, and try to avoid plastic mold manufacturing Unnecessarily complicated in.

2) Plastic mold structure design A good set of molds not only requires good processing equipment and skilled mold manufacturing workers, but also requires good plastic mold structure design, especially for complex structure molds, the quality of mold design accounts for 80% of the mold quality %above. A good mold design engineer needs to reduce processing costs, reduce the difficulty and time of plastic mold manufacturing on the premise of meeting customer requirements. 

3) To determine the selection of plastic mold materials and standard plastic molds, in addition to considering the accuracy and quality of the product, an appropriate choice should be made in combination with the processing equipment and actual heat treatment capabilities of the mold factory. In addition, in order to shorten the plastic mold manufacturing cycle, you can choose standard parts processing as much as possible. 

4) Processing and assembly of plastic mold parts In addition to reasonable mold structure and tolerance range, the precision of plastic molds is crucial to the processing and assembly of mold parts. Therefore, the choice of mold processing accuracy and processing methods has a very important position in plastic mold manufacturing.

5) Mold testing Mold testing is an important step to check whether the plastic mold manufacturing is qualified and to select the molding process. It can verify whether the demoulding is smooth or not, how the cooling effect is, and the influence of the size, position and shape of the gate on the precision and appearance of the product, etc.
