In today's mold manufacturing field, the continuous emergence of new materials is bringing new changes to the industry. For example, high-strength alloy steel is increasingly used in mold manufacturing. This material has extremely high strength and hardness, can withstand complex molding processes and high-intensity working pressure, and greatly improves the service life and stability of the mold. A certain automobile mold manufacturing company uses high-strength alloy steel to manufacture automobile cover molds, which has a service life of more than 30% longer than molds made of traditional materials. Not only that, new ceramic materials are also beginning to emerge in mold manufacturing. Ceramic materials have excellent wear resistance, high temperature resistance and corrosion resistance, and are particularly suitable for some processing fields that have extremely high requirements for mold performance, such as the manufacture of aerospace parts. A mold made of ceramic materials by an aerospace company can still maintain good dimensional accuracy and surface quality in a high temperature environment, providing a strong guarantee for the production of high-precision parts.
