Aluminum alloy die-casting parts can be manufactured as die-casting auto parts, die-casting auto engine pipe fittings, die-casting air-conditioning parts, die-casting gasoline engine cylinder head, die-casting valve rocker arm, die-casting valve seat, die-casting power fittings, die-casting motor end cover, die-casting housing, Die-casting pump housings, die-casting building accessories, die-casting decorative accessories, die-casting guardrail accessories, die-casting wheels, etc. With the continuous improvement of the development level of the domestic manufacturing equipment industry, the equipment level of the die-casting machine has also been significantly improved, the types of parts that can be manufactured are also constantly expanding, and the precision of the die-cast parts and the complexity of the parts have also been greatly improved. 

The problem of abrasion of aluminum alloy die castings is unavoidable. The characteristic is that along the direction of demolding, due to metal adhesion, the mold manufacturing slope is too small, resulting in scratch marks on the surface of the casting, which will become a scratch surface in severe cases.
cause:
1. Alloy adhesion mold.
2. The iron content in the aluminum alloy is less than 0.6%.
3. The ejection of the casting is skewed, or the axis of the core is skewed.
4. There are pressure scars on the core and wall.
5. The surface of the mold wall is rough.
6. The casting slope of the core and wall is too small or the inclination occurs.
7. The paint is often not sprayed.
