Product Introduction of Die Castings

Die castings are metal parts formed using a pressure casting process. Also known as die-cast parts or pressure castings, they are primarily manufactured using materials such as copper, zinc, aluminum, and aluminum alloys. This process utilizes high pressure to inject molten metal into a mold for rapid shaping, resulting in high precision, good surface finish, and small machining allowances. The design must consider factors such as wall thickness, casting fillets, and draft angles.

Based on equipment, die casting machines can be divided into hot chamber die casting machines (suitable for zinc and magnesium alloys) and cold chamber die casting machines (suitable for aluminum and copper alloys). In hot chamber die casting machines, the injection system is immersed in molten metal.

Die castings are widely used in automotive parts, engine pipes, motor end caps, and other fields. High-vacuum die casting technology can reduce porosity and improve weldability and heat treatment performance, playing an important role in the integrated die casting of new energy vehicles.

High pressure casting uses 15-100MPa pressure to inject into the mold, and the thinnest aluminum alloy part wall can be as thin as 0.5mm, which is suitable for parts such as engine cylinder blocks; vacuum die casting improves density by removing air from the cavity, and although the equipment cost is higher, the long-term benefits are significant.
