Zinc Die Casting
ZINC DIE CASTING
We make molds and provide Zinc Die Casting parts to global clients. Our zinc die casting machines are 80T to 250T press. Our common materials are Zamak #2, #3, #5, #7, ZA8 and ZA27. Zinc alloy die castings are usually used in the periphery of electronics and electrical appliances. Therefore, excellent appearance and good corrosion resistance are an important and necessary feature. The surface treatment of zinc alloy generally has the following treatment methods: painting, plating, e-coating, wiredrawing etc.
Sand blasting + Plating
Electroplating is a layer of copper, nickel, chromium, silver, gold and other metal layers with decorative effects on the surface treatment of zinc alloy castings by electrochemical methods.
Polishing + Wire-drawing
The metal wire drawing process can clearly show every fine wire mark, so that the fine matte hair gloss appears in the metal matte, and the product has a sense of fashion and technology.
E-coating
Electrophoretic paint is a kind of charged paint. Under the action of an electric field, the positively or negatively charged paint will move toward the cathode or anode, and deposit a film on the surface, which becomes a paint film after drying.
Painting
Painting is a cost-effective way to spray paint and varnish on the surface of zinc alloy die castings to achieve the effect of beauty and corrosion resistance. Usually, its pretreatment procoss is polishing.
