Pressure casting, commonly designated as die casting within industrial manufacturing contexts, constitutes a specialized metalworking process wherein molten or semi-molten metal material is injected into a prepared die cavity at accelerated velocities while simultaneously subjected to elevated pressure conditions, followed by a solidification phase that occurs under continued pressure

Die casting represents a manufacturing process that delivers dimensional precision and surface finish characteristics exceeding those achieved through alternative casting methodologies such as sand casting or gravity casting, particularly when producing components with complex geometries, thin wall sections, or integrated insert features that would prove challenging to manufacture through conventional approaches. The process enables fabrication of parts exhibiting substantial mechanical strength and hardness properties while maintaining elevated production rates per unit time, making it economically viable for medium to high-volume manufacturing scenarios across automotive, consumer electronics, and industrial equipment sectors.

Die casting, a manufacturing process that has become integral to modern industrial production, has achieved widespread adoption across multiple sectors including the automotive industry, agricultural machinery production, precision instrumentation manufacturing, and defense equipment fabrication. This metalworking technique encompasses two primary categories distinguished by material composition: black metal die casting, which involves ferrous materials, and non-ferrous metal die casting, which processes lighter, more corrosion-resistant alloys. Despite sharing the common designation of die casting, these two branches differ substantially in their operational methodologies and the specialized equipment required for implementation.

The variety of die casting products in China is diversified, including automobiles, motorcycles, communications, home appliances, hardware products, power tools, IT, lighting, escalator steps, toy lights and so on. With the improvement of technical level and product development talent, die casting product varieties and application fields continue to expand, and its die casting equipment, die casting mold and die casting process have undergone great changes.

Since the commercial production of die-cast aluminum alloy was initially established in 1914, this material category has undergone substantial expansion in concert with the parallel advancement of the automobile industry and concurrent innovations in cold chamber die-casting machine technology, which enabled manufacturers to achieve higher production volumes and improved dimensional precision in cast components. The evolution of die-casting processes during the twentieth century reflected broader shifts in automotive manufacturing toward lighter-weight structural materials that could reduce fuel consumption while maintaining adequate mechanical performance.
