The die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency. The main die casting alloys are: zinc, aluminium, magnesium, copper, lead, and tin; although uncommon, ferrous die casting is possible. It's a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high volume production. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small to medium sized castings, which is why die casting produces more castings than any other casting process.
The main die casting alloys are: zinc, aluminium, magnesium, copper, lead, and tin; although uncommon, ferrous die casting is possible.
1. Aluminium: lightweight; high dimensional stability for complex shapes and thin walls; good corrosion resistance; good mechanical properties; high thermal and electrical conductivity; retains strength at high temperatures. 2. Zinc: the easiest alloy to cast; high ductility; high impact strength; easily plated; economical for small parts; promotes long die life. 3. Magnesium: the easiest alloy to machine; excellent strength-to-weight ratio; lightest alloy commonly die cast. 4. Copper: high hardness; high corrosion resistance; highest mechanical properties of alloys die cast; excellent wear resistance; excellent dimensional stability; strength approaching that of steel parts. 5. Lead and tin: high density; extremely close dimensional accuracy; used for special forms of corrosion resistance. Such alloys are not used in foodservice applications for public health reasons.
