We produce zinc die casting parts from a few grams to more than 100 pounds with superior quality ready for assembly. we offer a broad range of zinc die casting surface finishing including powder coating, e-coating, shot blasting, chrome plating, and bright finish. The industries we serve include automotive, food dairy, machinery, medical, plumbing, watering, mining, petrochemical, electrical, energy, aerospace, submarine, and others.
The high-pressure zinc die casting process is carried out in an automatic machine suitable to withstand high pressure. The molten metal is pushed into two-piece steel die containing one or more cavities, each an exact inverse replica of the part or parts. The mechanical properties of pressure zinc die castings are generally superior to other casting processes because of the quick chill and rapid solidification that takes place when the molten metal comes into contact with the relatively cool steel side.
What Is Zinc Die Casting?
Zinc die casting is a metal casting process characterized by pressuring molten metal into the mold cavity. The mold cavity is created using two hardened tool steel molds that are machined to the net shape or near-net shape of the zinc die casting parts. The zinc die casting process allows products to be made with a high degree of accuracy and repeatability. The Zinc die casting process can also produce fine details such as textured surfaces or names without requiring further processing.
How is Zinc Die Casting Made?
Steel dies capable of producing tens of thousands of zinc castings in quick succession that must be made in at least two sections to allow the castings to be removed. These parts are firmly mounted in the machine and are arranged so that one is stationary (fixed die half) and the other one is movable (injector die half). To begin the casting cycle, the two mold halves are clamped together by a die-casting machine.
Molten zinc alloy is injected into the mold cavity and rapidly solidified. The mold half is opened and the zinc casting is ejected. Zinc die casting molds can be simple or complicated, with movable slides, cores, or other parts, depending on the complexity of the casting.
To date, the complete cycle of zinc die casting has been the fastest cycle to produce precision zinc parts. This is in stark contrast to sand casting, which requires new sand molds for each casting. Although the permanent mold process uses iron or steel molds instead of sand, it is much slower and less precise than zinc die castings.
