zinc die casting process
A zinc die- casting process is a precision metal casting technique that can easily achieve complicated shapes with great accuracy and little or none of the need for post-processing. The main objective of the use of zinc die casting is to produce parts that are dimensionally accurate, durable and have a good surface finish. Technically, this involves using zinc-alloy as it brings in the advantages of strength, ductility and wear resistance. The process employs high pressure to inject molten zinc alloy simply into a steel mold-termed a "die"These castings are later, when solidified, ejected or cut-off to size and finished as required. A typical die-cast part might be a gear for an automobile engine, with its high precision and strength at minimum weight.Zinc die casting is now used in automobile industry, electronics, telecommuncations and others, where fine parts requiring high quality and reliability prevail.
