Die casting is one of the casting methods which form products by pressure-injecting molten metal into metal molds. By creating precise metal molds, it is possible to create thin and complex forms while maintaining high precision. The smooth surface of die casting products requires less machine processing, and is easy to plate and paint. Since it allows mass-production while maintaining high quality, die casting products are used in variety of industries such as automobiles, home appliances, OA systems, and industrial machinery.
