What is Die Casting?

Die casting is a manufacturing process that produces metal parts using molds (also called dies). It involves forcing molten metal into a mold cavity (under high pressures) to create the desired metal parts.

The mold consists of two halves (usually made of heat-resistant steel grades) that form a cavity into which the liquid metal is pressed at pressures ranging from 1,000 to 20,000 psi. The die casting process comes in two typesㅡwhich are hot chamber and cold chamber die casting processes.

Both processes are suitable for fabricating high-quality die-cast parts; they only differ slightly in their casting method. The ideal die casting process primarily depends on the type of metal and part you intend to fabricate.

Hot Chamber and Cold Chamber Die Casting

The hot chamber die casting process, also called hot casting, involves completely immersing the cylinder chamber of the injection mechanism into the molten metal bath before beginning the casting process.

Through a metal feed system, molten metal is pumped into the die cavity to create the desired shape. The hot chamber die casting method is ideal for metals with low melting point temperatures (or metals that won’t dissolve when heated), such as zinc, lead, and magnesium alloys. The process also offers higher production rates than the cold chamber process.

Unlike in hot chamber die casting, the cold chamber die casting process eliminates the need for immersing the injection mechanism into the motel metal bath. Instead, the metal is contained in a holding pot and on a furnace to melt it to the necessary temperature.

Next, the molten metal is ladled from the pot into the die casting machine to create die-cast parts. The cold chamber die casting process is ideal when working with materials having high melting point temperatures like aluminum and copper.
