Hot Chamber And Cold Chamber Die Casting. In the process of die casting, molten metal in injected forcibly into mold cavities, or “dies”, under very high pressure. Because this method of molding metal is extremely versatile, die casting is widely used as a method for forming metals into specific shapes. While it may use a similar process as mold casting, die casting uses pressures of up to 10 to 210mpa to inject metal into the die. The resulting material exhibits uniformity of parts, dimensional accuracy, and smooth surface finishes.
There are many different materials used in zinc die casting, such as copper, aluminum, tin, magnesium, and lead. However, aluminum is the most widely used compared to these other materials as the metal is more malleable, and is good for creating large size cold chamber die castings, to die castings composed of tiny and complex parts.
There are two processes used for die casting, namely the cold chamber which produces cold chamber die castings, and the hot chamber process. To produce cold chamber die castings, a cold cylinder is injected with molten metal. With less time exposure given for the metal to be propelled into the mold, cold chamber processing is more often used for metals that easily meld with iron at very high heat. The cold chamber process is also used for metals that have high melting points.
On the other hand, in the hot chamber process, the pressure found in the die cavity connected to it becomes permanently a part of the molten material. A plunger is propelled toward an area that is non-pressurized, uncovering the inlet port appended to the pressure cylinder.
