Is die casting a permanent mold?

May,17 2024

Yes, die casting is a type of permanent mold casting. In die casting, molten metal is forced into a mold cavity under high pressure. The molds used in this process, known as dies, are typically made from durable materials such as steel or other hard alloys. These dies can be used repeatedly to produce a large number of identical metal parts, making the process both efficient and cost-effective for high-volume production.



There are two main types of die casting:

Hot-Chamber Die Casting: Used primarily for metals with low melting points, such as zinc, magnesium, and lead.

Cold-Chamber Die Casting: Used for metals with higher melting points, such as aluminum and copper alloys.


In both methods, the die acts as a permanent mold that can be used many times, distinguishing die casting from other casting processes that use expendable molds, like sand casting or investment casting.
