Cold Chamber Die Casting
The Cold Chamber Die Casting Process
Cold Chamber Die Casting is one of two major die casting processes, the second being Hot Chamber die casting. The primary difference between Cold Chamber and Hot Chamber die casting is that, in the Hot Chamber process, the source of molten material is attached to the die casting machine. In the Cold Chamber process, the molten metal is introduced to the shot chamber from an external source.
Cold Chamber die casting machines are used when working with alloys with high melting points, such as aluminum, brass, and magnesium. These alloys are not used in Hot Chamber machines because they would damage the pump system. The transport of molten material is typically done using a ladle, which can be handled automatically or manually. Casting cycles can range from 10 seconds for small die casting machines up to two minutes for larger units.
The Cold Chamber die casting process is more common in the manufacturing industry due to its low cost of production and the durability of the finished product.
