Zinc alloy die-casting is a part of pressure casting. It is a pressure casting mechanical die-casting machine equipped with casting molds. The zinc or zinc alloy heated in liquid state is poured into the inlet of the die-casting machine. Zinc parts or zinc alloy parts with limited shapes and sizes of molds, such parts are usually called zinc alloy die castings.
Features and applications of zinc alloy die casting technology
1. Relatively large.
2. The casting performance is good, and the precision parts with complex shapes and thin walls can be die-casted, and the surface of the castings is smooth.
3. Surface treatment: electroplating, spraying, painting, polishing, grinding, etc.
4. It does not absorb iron during melting and die casting, does not corrode the molding, and does not stick to the mold.
5. Has good mechanical properties and wear resistance at room temperature.
6. Low melting point, easy to die cast.
The main features of zinc alloy die-casting are that the melting point of the zinc alloy is low, and the melting process of the zinc alloy occurs when the temperature reaches four hundred degrees. This is better for zinc alloy die-casting. Zinc alloy does not absorb iron during melting and die casting, and the zinc alloy casting performance is good. In the die casting process, many precision parts with complex shapes can be processed. The surface of the casting looks very smooth after the die casting is completed. At the same time, the proportion of zinc alloy is relatively large.
Zinc alloy die casting technology is widely used in injection molding process, its main advantage is to focus on improving the quality of castings.
