Die Casting
Casting is a manufacturing process by which liquid or molten metal under high pressure, is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify.
The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are (for example)epoxy, concrete, plaster and clay. It is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.
Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter and tin based alloys.
Equipments
Depending on the type of metal being cast, a hot- or cold-chamber machine is used. There are two basic types of die casting machines:
✔ Hot-chamber machines
✔ Cold-chamber machines
These are rated by how much clamping force they can apply.
