Aluminum die casting mold or molding process introduction
Advantage of aluminum die casting process
B.good surface finish and good dimensional accuracy die casting generally has good surface finish and good dimensional accuracy. For many parts, post-machining can be totally eliminated, or very light machining may be required to bring dimensions to size.

Disadvantage of die casting molding process
B.high porosity Though the porosity of die casting can be adjusted by using much higher pressure with a much larger and heavier mold, the porosity can not be avoided and is much more than that is of low pressure casting and gravity casting. Furthermore,porosity leads die casting parts to be not suitable for heat treatment.Thus the consistence can not be compared with gravity castings.

Illustration of cold chamber die casting molding process
After the molten aluminum alloy is ladled in to the cold chamber, the piston will inject it into the cavity of the die casting mold through three different pressure phrases. The pressured molten aluminum alloy gets in sequence through spure system, running system and gate system into the cavity of the die casting mold.
The filled cavity with affection of cooling system shapes the desired die casting products. Then the moving die moves away from the fix die, while the ejectors push out the casting.
