It is closely related to mold design and manufacture and plastic processing. The success or failure of plastic processing depends largely on the effect of mold design and the quality of mold manufacturing, plastic mold design, and plastic design. Therefore, in the design of plastic molds, structural elements should be fully considered, mainly:

Parting surface, the mold is closed when closed, and the contact surface is flushed with each other. Its position and shape are selected by the shape and appearance of the product, thickness, molding method, post-processing process, mold type and structure, mold release method, and molding machine structural factors.

Second, the gating system, that is, the cavity from the molding machine nozzle to the feed channel, includes gates, splits, gates, and cold stock points. The gate location should be chosen so that the cavity is filled, the molten plastic is in a good flow state and solid flow path, and the cold material attached to the product by the gate is easily formed and removed from the top of the mold (hot path mold).

Plastic shrinkage and various factors that affect product dimensional accuracies, such as mold manufacturing and assembly errors, and mold wear. In addition, when designing the compression mold and injection mold, the matching of the process and structural parameters of the molding machine should also be considered. Has been widely used in plastic mold design and computer-aided design technology
