Product Details Company Profile

The excellent performance of graphite mold: 1 excellent thermal and electrical conductivity and low coefficient of thermal stability good expansion 2 line and anti heat shock 3 resistance to chemical corrosion and most metal is not easy to react at high temperatures (above 4 in most of the copper matrix sintering temperature of 800 °C) intensity increased with the increasing of temperature 5 good lubrication and abrasion resistance of 6 easy processing, mechanical processing performance is good, can mold into complex shape, high precision

Application of the graphite mould at present, graphite mold is mainly obtained the widespread application in the following aspects:

1 non-ferrous metal continuous casting and semi graphite mould continuous casting: in recent years, both at home and abroad are popularized by the molten metal state (continuous or semi continuous) method for producing bar or pipe and other advanced. In the domestic copper, copper alloy, aluminum, aluminum alloy and so on have already started using this method. Artificial graphite as a continuous casting of nonferrous metal or semi continuous casting mold is considered to be the most suitable materials. Production practice has proved that, as a result of the graphite mold, because of its good thermal conductivity properties (thermal conductivity of the solidification rate of metal or alloy), good self-lubricating performance factors such as mold, the casting speed, and because the ingot precise size, smooth surface, uniform crystalline structure, can be processed directly under the procedures the. This not only greatly improve the rate of finished products, reduce waste, but also greatly improve the quality of the products. Method of continuous casting method and horizontal continuous casting of two vertical continuous casting.

2 pressure casting mould: artificial graphite materials have been successfully used for the pressure casting of non-ferrous metals. For example, manufacturing with artificial graphite material pressure casting mold production of zinc alloy and copper alloy castings have been used for automobile parts etc..

Graphite mould 3 centrifugal casting: Shi Momo has been successfully applied in centrifugal casting. The United States has a wall thickness of 25 mm above the artificial graphite mould of centrifugal casting bronze sleeve. In order to prevent the artificial graphite mold burning, can take some measures to prevent oxidation. Casting a certain number of castings, if it is found that the mold surface burn, the mold hole size expanded to casting large size casing.

4 hot pressing die: artificial graphite hot pressing die for has the features of pressurized sintering cemented carbide: if the compaction temperature to 1350-1450 degrees, the unit pressure can be reduced to 67-100 kg / cm2 (i.e. cold pressure 1/10) can; two is pressurized and heated in the same procedure, get the sintering of the compact sintered can short time.
