When people talk about cars, the first thing that appears in front of them is the car's body, which represents the image characteristics of a car. Therefore, automobile molds, in a narrow sense, are the general term for all stamping product molds on the car body, that is, "stamping molds", such as top cover flanging molds. But in a broad sense, "automobile mold" is the general term for the molds used to manufacture all parts of automobiles, such as automobile stamping molds, automobile forging molds, automobile casting wax molds, automobile injection molds, and automobile glass molds.

The characteristic of the molding process of the injection mold is that the plastic is placed in the heating barrel of the injection molding machine, and the plastic is heated and melted. Driven by the screw or plunger of the injection molding machine, it enters the injection mold cavity through the nozzle and the casting system of the mold. The mold cavity is pressure-maintained, cooled, and solidified to form. Injection molding can not only form plastic parts with complex shapes but also has high production efficiency and good quality. Therefore, injection molding occupies a large proportion in the molding of plastic parts, and Plastic Injection Mold occupies more than half of the plastic molding mold. Injection molding machines are mainly used for the molding of thermoplastics. In recent years, they have also been gradually used for the molding of thermoset plastics.
