Die Casting

As a trusted casting manufacturer in China, SAIVS also manufactures high-quality Die casting. The range is casted or fabricated using quality material and high end technology, in compliance with industrial quality standards. The area of the foundry covers more than 10020 square meters, it owns 158 workers ,35 of them are engineers. There are 12 die casting machines, from 200 tons to 1600 tons, the foundry owns more than 30 sets of special inspection facilities, such us, CMM, spectrum analysis and other simulation software. The foundry is specialized in producing the covers of auto part and motors and other aluminium alloy and zinc alloy die casting. Also, we assure our clients that these Die casting are designed as per their requirements.


Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. Die-casting can be done using a cold chamber or hot chamber process.


In a cold chamber process, the molten metal is ladled into the cold chamber for each shot. There is less time exposure of the melt to the plunger walls or the plunger. This is particularly useful for metals such as Aluminum, and Copper (and its alloys) that alloy easily with Iron at the higher temperatures.

In a hot chamber process the pressure chamber is connected to the die cavity is immersed permanently in the molten metal. The inlet port of the pressurizing cylinder is uncovered as the plunger moves to the open (unpressurized) position. This allows a new charge of molten metal to fill the cavity and thus can fill the cavity faster than the cold chamber process. The hot chamber process is used for metals of low melting point and high fluidity such as tin, zinc, and lead that tend not to alloy easily with steel at their melt temperatures.

Die casting molds (called dies in the industry) tend to be expensive as they are made from hardened steel-also the cycle time for building these tend to be long. Also the stronger and harder metals such as iron and steel cannot be die-cast.
