Aluminum Die Castings are widely used in equipment parts, power parts, petroleum machinery parts, train parts, auto parts, volutes, valve bodies, brackets, kitchen supplies, bicycle parts, textile machinery parts, etc., and are widely used. This is because die castings have many advantages that other metal die castings cannot match, such as light weight, corrosion resistance, and beautiful appearance. Aluminum die castings have always been favored by users in all walks of life. Since the lightweight of automobiles, die castings have been widely used in the automotive industry.

Aluminum Die Castings

Aluminum Die Castings are divided into three areas: correction, repair and surface finishing. Some die castings will be deformed to varying degrees during solidification, cooling and heat treatment, making some dimensional differences, and corrective measures need to be taken to repair. Calibration is mainly performed at room temperature or under mechanical force. When the deformation is too large, the self-weight or external pressure weight of the die-casting part can also be used for high-temperature correction in the heating furnace.

How to improve the surface finish quality of Aluminum Die Castings:

1. The wall of the die-casting product cannot be too thin. Large-area thin walls are prone to defects such as under pouring and cold insulation.

2. Selection of wall thickness of die-casting products: In general, the wall thickness should not be greater than 4.5 mm. The suitable wall thickness of small and medium-sized aluminum castings is 1-3 mm for zinc alloy, 1.5-4 mm for aluminum-magnesium alloy, and 2-4 for copper alloy. mm.

3. The wall thickness of die-casting products should be uniform, which is conducive to the solidification of the molten alloy after "filling", and can avoid defects such as casting stress, shrinkage cavities, and cracks
