Characteristics of aluminum alloy die casting industry
The many characteristics of the die casting process make it show great advantages in improving the precision level, production efficiency and surface quality of non-ferrous metal alloy castings. With the development of industries such as automobiles and motorcycles, and the realization of design requirements such as improving the quality of die castings, saving energy consumption, and reducing pollution, the application scope of non-ferrous metal alloy die castings, especially light alloy aluminum alloy die castings, is rapidly expanding. Have
The data shows that it is becoming an important development trend in industrialized countries to replace steel castings with aluminum alloy and magnesium alloy castings. At present, die casting has become one of the most widely used processes in the forming process of aluminum alloys for automobiles, accounting for 50% of various automobile forming processes.
The characteristics of aluminum alloy die castings are:
1. The surface finish of the product is good, generally reaching Ra6.3 or even Ra1.6.
2. No heat treatment.
3. The product has high air tightness, high casting strength and surface hardness, but low elongation. Too thick wall thickness is easy to generate pores.
4. The mold cost is high and the service life is short.
5. High production efficiency.
6. Thin-walled parts can be produced with small machining allowance.
7. Special aluminum alloy cannot be used.
