For 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. Such as Aluminium Die Casting we ca offer.
For 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. Such as Zinc Die castings, Copper Die castings we offer.
Pressure die casting is a competitive china sand casting method when the components are needed at high volumes or when better tolerances and surface finish are required than can be achieved by gravity die casting. The need for machining is very low due to the close casting tolerances. Heat treatment of pressure die casting is not possible but due to the high rate of solidification the mechanical properties are good.

Can predict the next few years, the casting mold production in China will continue to get strong thrust from the domestic auto industry.

Relative to Southeast Asia and Middle East countries, China mold technology, quality and price advantage, export prospects. Foreign companies into China, the mold resold and export will also become an important part of Chinese mold exports. Luobai Hui said that China sand casting mold production costs much lower than abroad, with the mold manufacturing technology to improve and improve the quality of not only reduce the import of mold, and may gradually develop export markets, to export more mold. During the second five, die imports in the short term will continue to maintain growth momentum, the mold for export will have great development.
