Different hardware molds, Plastic Injection Molds, and special molds according to the molded material. Hardware molds are divided into: including stamping molds, forging molds, extrusion molds, extrusion molds, die-casting molds, forging molds, etc.; non-metallic molds are divided into plastic molds, inorganic non-metallic molds, sand molds, vacuum molds, and paraffin molds, etc. . Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic molds can generally be divided into injection molding molds, extrusion molding molds, gas-assisted molding molds, etc.

Under the action of external force, the blank becomes a tool with a specific shape and size. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and the forming and processing of engineering plastics, rubber, ceramics, and other products by compression molding or injection molding. The mold has a specific contour or cavity shape, and the contour shape with a cutting edge can be used to separate the blank according to the contour shape (punching). The shape of the inner cavity can be used to obtain the corresponding three-dimensional shape of the blank. The mold generally includes two parts: a movable mold and a fixed mold (or a convex mold and a concave mold), which can be separated or combined. The mold is a precision tool with a complex shape and can withstand the expansion force of the blank. It has high requirements for structural strength, rigidity, surface hardness, surface roughness, and processing accuracy. The development level of mold production is an important symbol of the mechanical manufacturing level of Automotive Mold Manufacturers.
