There are a large number of molds in our factory. However, their overall manufacturing process is the same. There is a set of very detailed and strict manufacturing process procedures.
The first step is to require the designer to design and produce the task book of the molded plastic parts according to the actual situation. It needs to include formal part drawings that have been approved and signed, and the grades and transparency of plastics used must be indicated in the drawings. The second is the specification or technical requirements for plastic parts. Furthermore, a sample of a plastic part is required. There is also basic information such as production volume.
Then, the plastic part craftsman proposes a mold design task book according to the task book for molding plastic parts. Finally, the mold designer designs the mold based on the molding plastic parts task book and the mold design task book.
The second step is to collect, analyze, and digest raw data. It is necessary to collect and sort out relevant product design, molding process, molding equipment, mechanical processing and special processing data for use in designing molds.
Digest the drawings of plastic parts, understand the use of parts, and analyze the technical requirements of plastic parts such as manufacturability and dimensional accuracy. For example, what are the requirements for plastic parts in terms of appearance shape, color transparency, and performance; whether the geometric structure, slope, and inserts of plastic parts are reasonable; Assembly, electroplating, bonding, drilling and other post-processing. Select the size with the highest dimensional accuracy of the plastic part for analysis to see if the estimated molding tolerance is lower than the tolerance of the plastic part, and whether a satisfactory plastic part can be formed. In addition, it is necessary to understand the plasticization and molding process parameters of plastics.
