1. According to the shape and function of the injection molding products, consider the segmentation to ensure the product processability. In order to ensure the good manufacturing technology of plastic injection molding and injection mold, as much as possible split into suitable grinding workpiece shape, and pay attention to improve EDM to reduce manufacturing costs.

2. The standardization of injection mold design should be considered in the process of disassembly, which needs to be convenient for assembly, disassembly and maintenance, reduce labor intensity and save maintenance costs.

3. The thinner the core parts are, the better. If the core parts are too thin, the strength of the injection mold core will be reduced, which is easy to wear or damage, which is not conducive to production and maintenance. There are more parts and more tolerances will be accumulated, which will need to improve the machining accuracy of each part. This will lead to an increase in manufacturing hours and manufacturing costs
