Die-casting is the process where molten metal is injected into a mold under high pressure in the range of 10-210MPa

This will result in a highly uniform casting with very good surface finish and exceptional dimensional accuracy

Usually, this can either eliminate or greatly reduce the machining required to finish the part

We can offer both the cold chamber process and the hot chamber process

Cold chamber process, metal is ladled into the injection chamber for each shot

There is less exposure of the molten metal to the chamber walls and plunger

This is very useful for aluminum and copper alloys that would easily alloy with iron at elevated temperature

Hot chamber process has the injection chamber which is connected to the die cavity permanently immersed in the molten metal

Hot chamber process is used for metals of low melting point and high fluidity such as tin and zinc

Materials that Donrex offers are alloys of aluminum, copper, zinc and magnesium

Zinc castings can be made with thinner wall thickness than aluminum due to high melt fluidity

We can produce parts from very small to about 30kg for aluminum, 10kg for magnesium, 50kg for zinc and 5kg for copper
