PVD Coating For Die Casting Tool
Physical Vapor Deposition (PVD) Coating is a advanced surface treatment technology widely used in various industrial applications, including die casting tools. Die casting is a manufacturing process that involves forcing molten metal under high pressure into a mold cavity, known as a die. The die casting tools, which include the dies themselves, as well as other components like cores and ejector pins, are subjected to extreme conditions such as high temperatures, mechanical stress, and corrosive environments.
PVD coatings enhance the performance and longevity of these tools by providing superior wear resistance, corrosion protection, and improved surface properties.
BE-CU prototype company’s surface treatment partner and shareholder use PVD technology for coating a wide range of hardware, plastic, die-casting molds, cutting tools, and precision components.Common Problems of Hardware Molds:
Die-casting molds (for materials such as aluminum, zinc, and magnesium) typically operate under high-temperature, high-pressure, and high-speed conditions. When molten metal is injected into the molding cavity under pressure, it reacts chemically with the substrate, causing partial surface alloying. This process also leads to erosion of the mold surface, thermal cracking due to rapid cooling after exposure to high temperatures, and material deposition from molten metal adhering to the mold surface.
These harsh conditions significantly shorten the lifespan of molds and inserts, requiring the production of numerous spare molds to meet order demands. Through our advanced composite treatment process, mold lifespan can be effectively extended, significantly improving production efficiency and reducing manufacturing costs.
