Die casting
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. 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.
Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminum, magnesium, lead, pewter and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high-volume production. 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.[1] Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.
Two variants are pore-free die casting, which is used to eliminate gas porosity defects; and direct injection die casting, which is used with zinc castings to reduce scrap and increase yield.

Advantages of Metal Die Casting Process
1. Aluminum (aluminum alloy) die casting has advantages of lightweight, excellent corrosion resistance, good mechanical properties, high thermal and electrical conductivity, high dimensional stability for complex shapes and thin walls, and retains strength at high temperature.
2. Zinc die casting is the easiest alloy to cast and plate, which features high ductility, high impact strength, promoting long die life as well as economical for small parts.
3. Magnesium die casting is the lightest and easiest alloy to manufacture with excellent strength-to-weight ratio.
4. Copper (brass, bronze) die casting features high hardness, good corrosion resistance, highest mechanical properties of alloys die cast, good wear resistance, excellent dimensional stability and high strength that approaching steel parts.
5. Stainless steel die casting has high degree of dimensional accuracy and surface finish, with a small amount of mechanical processing work, which greatly saves a large equipment, metal material and working hours.
6. Lead and tin die casting high density, extremely close dimensional accuracy, used for special forms of corrosion resistance.

ZINC-ALUMINUM DIE CASTING
ZA alloys represent a new family of zinc-based die casting materials which contain higher aluminum content than standard zinc alloys. These alloys provide high strength characteristics plus high hardness and good bearing properties. Thin wall castability characteristics and die life are similar to zinc alloys.

ZA-8 is recommended for hot chamber die casting, whereas ZA-12 and ZA-27 must be cast by the cold chamber die casting process. All ZA alloys offer similar creep properties and are superior to standard zinc alloys.

ZA-8 — Provides strength, hardness and creep properties.

ZA-12 — Provides excellent bearing properties with strength and hardness characteristics between ZA-8
and ZA-27, plus good dimensional stability properties and somewhat better castability than ZA-27.

ZA-27 — Offers the highest mechanical properties of the ZA family and is, therefore, recommended when maximum performance is required.
