New technologies and applications in die casting mold surface treatment!


Die casting molds constitute a major category within the broader field of molds. With the rapid development of China's automobile and motorcycle industries, the die casting industry has entered a new era of growth. Simultaneously, this has led to even higher demands on the comprehensive mechanical properties and lifespan of die casting molds. Meeting the constantly rising performance requirements relies not only on the application of new mold materials; it also necessitates the application of various surface treatment technologies to the surface of die casting molds in order to achieve high efficiency, high precision, and a long lifespan. Among various types of molds, die casting molds operate under particularly harsh conditions.

Could you share information on how graphite material is made into ductile iron?


Ductile iron is cast iron in which the graphite exists in a nodular form. Due to the unique structure of graphite, it possesses special properties: high-temperature resistance, electrical and thermal conductivity, smoothness, chemical stability, plasticity, and thermal shock resistance. Because of these properties, graphite is widely used in the foundry industry and is favored by foundry companies.
