Heated-manifold direct-injection die casting, also known as direct-injection die casting or runnerless die casting, is a zinc die casting process where molten zinc is forced through a heated manifold and then through heated mini-nozzles, which lead into the moulding cavity. This process has the advantages of lower cost per part, through the ...
A large problem with early zinc die casting materials was zinc pest, owing to impurities in the alloys. [3] Zamak avoided this by the use of 99.99% pure zinc metal, produced by New Jersey Zinc's use of a refluxer as part of the refining process. Zamak can be electroplated, wet painted, and chromate conversion coated well. [4]
Risdon Zinc Works (trading as Nyrstar Hobart) is a major zinc refinery located in Lutana, a suburb of Hobart, Tasmania, Australia.The smelter is one of the world's largest in terms of production volume, [5] producing over 280,000 tonnes (280,000 long tons; 310,000 short tons) [6] annually of high-grade zinc, primarily as die-cast alloys and continuous galvanising-grade alloys.
Under the name of John Guest Engineering, the newly established company specialized in tool making and precision engineering. It operated out of a small building that was known as Factory 1. The following year, John Guest Engineering merged with Guest Castings Ltd - a company specializing in zinc die-casting. This business also operated out of ...
A die-cast toy (also spelled diecast, or die cast) is a toy or a collectible model produced by using the die-casting method of putting molten lead, zinc alloy or plastic in a mold to produce a particular shape. Such toys are made of metal, with plastic, rubber, glass, or other machined metal parts.

The die casting process forces molten metal under high pressure into mold cavities (which are machined into dies). Most die castings are made from nonferrous metals, specifically zinc, copper, and aluminium-based alloys, but ferrous metal die castings are possible. The die casting method is especially suited for applications where many small to ...
