Die Casting Process
Die casting is a metal casting process that actually is forcing molten metal under high pressure into a mold cavity. The mold cavity is constructed using two hardened tool steel dies which have been machined into shape and work like an injection mold during the process.
Most of die castings are made from non-ferrous metals, zinc, copper, aluminium, lead, pewter, magnesium and tin-based alloys.
There are two main types of die casting machines –
1. hot chamber machines (used for alloys with low melting temperatures – zinc)
2. cold chamber machines (used for alloys with high melting temperatures – aluminum).
The most popular approaches to produce correct pieces is aluminum die casting.
