What are the problems with the high melting point of zinc alloy die casting?

Zinc alloy die casting is a precision casting method that uses high pressure to force metal melt into a metal mold with complex shapes. It is a precision casting method. Regarding its melting point, it is a place that needs special attention, so what are the problems caused by the high melting point of zinc alloy die-casting? The following is a brief introduction to its related knowledge points.

1. The high melting point of zinc alloy die-casting will destroy the composition of zinc alloy die-casting parts. When the magnesium and aluminum in the zinc alloy are lost due to temperature problems, the composition of the alloy will be changed, thereby affecting the quality of the product and the rejection rate. greatly increased.

2. The melting point of zinc alloy die-casting is high, and the energy consumption cost will also increase. Generally, the set temperature of zinc alloy die-casting in the production process is 410 °C, and poor zinc alloy may need to be set to above 430 °C. Generally, if the temperature of the zinc alloy die-casting machine in the zinc alloy die-casting factory is increased by 10 °C, the annual electricity cost will increase by 5,000 yuan. If diesel is used, the cost will increase by about 8,000 yuan.

3. Zinc alloy die-casting has a high melting point and shortens the service life of hot-worked parts. When the temperature of the crucible is too high, it will accelerate the wear and corrosion of the hammer handle, gooseneck, crucible, etc., which will cause many production problems, some may directly scrap the equipment, and the cost will be greatly increased.

4. The melting point of zinc alloy material increases, which will cause great damage to the mold, which will reduce the service life of the mold, thereby increasing the production cost.

5. Zinc alloy die casting has a high melting point, and the resulting zinc slag will also increase, and the cost of effective alloys will greatly increase.
