The common zinc alloy die casting parts in our lives include some die casting hardware such as lamps, furniture, luggage, hooks, belt buckles, etc., as well as some electronic cigarette industries that have developed rapidly in recent years, and many electronic cigarette shells also use zinc alloy die casting. Zinc alloy has the characteristics of low melting point, corrosion resistance, small solidification temperature range, easy filling and forming, small shrinkage tendency and so on. It can die cast die castings with complex shape, thin wall, smooth surface and high dimensional accuracy. Moreover, the die casting is formed in one step, and the production efficiency is very high. However, it is necessary to develop independent molds for each product before die casting, so the development time and cost in the early stage are relatively high, so zinc alloy Die Casting Products are more suitable for medium and large-scale production.
SCZY has an internal independent mold development workshop, we can ensure the delivery time and quality. There are also independent production equipment for zinc alloy and aluminum alloy, and there is also a special follow-up secondary precision CNC machining department. Our departments are closely linked and coordinated to ensure product quality and production delivery to the greatest extent possible.
