For automobile mold manufacturers, whether the automobile mold is made accurately and qualified will affect the efficiency of mold machining and mold structure assembly after the casting is returned to the factory. The most important component of automobile molds is the cover mold, which is mainly a cold stamping mold. In a broad sense, "automobile mold" is the general term for molds for manufacturing all parts of a car, such as stamping molds, injection molds, forging molds, casting wax molds, glass molds, etc.
