What is Cold Chamber Die Casting?

Cold Chamber Die Casting for high volume, versatile, cost effective manufacturing.

CWM uses the cold chamber die casting method for our aluminum production. With cold chamber die casting, molten metal is delivered from a central melt furnace to the holding furnace at the machine. With each cycle, a calibrated amount of molten metal is transferred to the machine’s shot chamber via an automated ladle transfer system.

The programmable hydraulic valves on the machine then actuate a plunger which forces the molten metal into the die under very high pressure and speeds. Once the molten metal solidifies, the plunger is released and the part is ejected onto a conveyor where it is transferred to the next operation.

The aluminum cold chamber die casting process is ideal for thicker walled parts requiring maximum strength.

CWM has 11 aluminum cold chamber die casting centers, ranging from 300 to 1000 tons of locking force.  Castings can be produced in a range of sizes from 0.75” x 0.75” to 18” x 18”.
