In practice, zinc casting is mainly applied to some small, high-value products. Also, zinc usually mixes with other materials such as aluminum, copper, titanium, magnesium, etc. to become a zinc-based alloy for the casting product. The fact is, zinc alloy quite fits the die-casting process, thanks to its property of fasting filling and fast cooling capabilities.
Features of Zinc Casting Alloys
Good casting performance: zinc casting alloys can be made to die-cast complex shapes, thin-walled precision parts, and smooth casting surfaces.
Surface treatment: electroplating, spraying, painting, polishing, grinding, etc.
Melting and die-casting: no iron absorption, no corrosion of the products made by die casting, no sticky mold.
Good room temperature mechanical properties and wear resistance.
Low melting point: melting at 385℃, easy to die-casting molding.
Zinc Alloy Die Casting Overview
Different from squeeze die casting, Zinc alloy die casting is a kind of pressure casting part, to uses a pressure casting machine with a casting mold installed. The zinc or zinc alloy heated to a liquid state is poured into the inlet of the die-casting machine and after die casting cast zinc parts or zinc alloy parts of the shape and size restricted by the mold. Such parts are usually called zinc alloy die castings. As a zinc die-casting manufacturer, Rayforce provides high-quality zinc die-casting products for customers.
