First of all, zinc die casting are manufactured by high pressure, but their chemical stability is poor, and they are prone to oxidation, discoloration and corrosion in the air. Therefore, China Zinc Die Casting Manufacturer must electroplate or paint the surface state of die castings so that they can get quality control.
When designing the geometric shape of zinc die casting, structures such as deep recesses of blind holes should be avoided as much as possible. Therefore, it is required to set aside drainage process holes which are convenient for the flow of solution gas in parts design without affecting the appearance and use. In this way, not only plating can be carried out well, but also the pollution degree of plating solution can be reduced. The surface of zinc die casting is dense.
