5 details to be paid attention to when casting zinc alloy.

Zinc alloy die casting is made of zinc alloy material as base material, and the die casting is made by high temperature ** and low temperature cooling, so as to form alloy die casting products of various shapes. Zinc alloy die casting has a lot of advantages, such as good casting performance, smooth surface and so on. It can also be used for various surface treatment processes such as electroplating and spraying. At present, the use of zinc alloy die casting is more and more widely used in mechanical parts.

1, it is a special reminder that zinc alloy die casting must pay attention to the following aspects:

The ratio of zinc alloy die casting to metal proportion is stipulated. Zinc is the main metal, and then a certain amount of aluminum, magnesium and copper are added to produce the zinc alloy ingots required for production, which is the basic of qualified alloy die casting.

2. When the raw material of zinc alloy die casting is in the furnace, the ratio of old and new raw materials should be at 7: ratio 3, which is the best ratio, which can reduce the loss of aluminum when the zinc alloy is recast.

3. After the raw material is made, the temperature of the melt water shall not exceed 430c. **oid unnecessary loss of metal at high temperature. There are also post-production electroplating waste that can be re-cast in the furnace alone.

4. It is better to conce**ate on all die-casting parts, and melt zinc alloy ingots in the same furnace. This will both reduce the cost of the melt and the ma**mum utilization of the flux, ensuring that each process is accurate.

5. It is not necessary to increase the cost of zinc alloy die-casting. Be careful to store storage in a well-ventilated, non-humid, clean and clean ware**, and prevent impurities.
