Brief Introduction
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, aluminium, 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.Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.
Cast metal
The main die casting alloys are: zinc, aluminium, magnesium, copper, lead, and tin; although uncommon, ferrous die casting is also possible.[6] Specific die casting alloys include: zinc aluminium; aluminium to, e.g. The Aluminum Association (AA) standards: AA 380, AA 384, AA 386, AA 390; and AZ91D magnesium.The following is a summary of the advantages of each alloy:
Zinc: the easiest metal to cast; high ductility; high impact strength; easily plated; economical for small parts; promotes long die life.
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.
Magnesium: the easiest metal to machine; excellent strength-to-weight ratio;
lightest alloy commonly die cast.
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.
Silicon tombac: high-strength alloy made of copper, zinc and silicon. Often used
as an alternative for investment cast steel parts.
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. Type metal, an
alloy of lead, tin and antimony (with sometimes traces of copper)
is used for casting hand-set type in letterpress printing and hot
foil blocking.
Traditionally cast in hand jerk molds now predominantly die cast after the industrialisation of the type foundries. Around 1900 the slug casting machines came onto the market and added further automation, with sometimes dozens of casting machines at one newspaper office.
