These three knowledge points should be understood before injection molding

1. In depth research and analysis of injection mold structure and related technical development requirements. The structure of plastic parts can determine the complexity of injection mold structure, and the technical enterprise requirements of plastic parts (dimensional accuracy, surface roughness, etc.) determine the difficulty of injection mold manufacturing and molding process. Therefore, for students who do not meet the special educational requirements of plastic injection molding, unreasonable structure and shape, we should clearly put forward the work plan of improving teaching design of injection parts, Otherwise, it will increase the difficulty of injection mold design and manufacturing and injection molding process.

2. Be familiar with the technical specifications of injection molding machine. There are many types of molds, as well as equipment, so choose different injection molding machines according to different molds.

3. Understand the processing performance and process performance of plastics, including the flow line of plastic melt, which can reach a large flow distance ratio: analyze the flow resistance of the whole flow channel and cavity, discharge the original air in the mold cavity, the possible crystallization, direction and internal stress of plastics in the injection mold, plastic cooling shrinkage and compensation, and the temperature requirements of plastics on the injection mold.
