Aluminum alloy injection molding new technology

[China Aluminum Network] spray casting process is characterized by: the molten metal in a very short period of time, through the atomizing device to spray the metal liquid into small particles (10 - 500 microns), spray deposited in the scheduled On the deposition board.

The big feature of the Injection Molding process is the rapid cooling, solidification and atomization of the molten metal, which enables the supersaturated second phase in the molten metal to be refined and evenly dispersed, which overcomes the slow cooling rate in the traditional casting process. The resulting macro segregation and organizational coarseness. The injection molding process is directly formed from a molten metal into a solid body, which also overcomes the problems of cumbersome and multi-pass treatment procedures, poor organization density, and severe powder oxidation during the powder metallurgy process, resulting in a higher ratio of injection molding materials. Powder metallurgy materials have low porosity and good properties.

The advantages of injection molding are many, such as: high stacking rate, (usually 0.25 - 1.7 kg/s); shape can be complex, can reduce the processing process; alloys are diversified, components are not limited; coarse embryos The density of the body is higher than that of powder metallurgy, and the oxide content is also small.

In the injection molding process, the molten metal can be rapidly cooled, solidified and solidified into a solid shape, which overcomes the problems of macro-segregation in the conventional casting process and oxidation in the powder metallurgy process, and exhibits excellent material properties.

The injection molding process method is a new type of aluminum alloy molding method. It is a choice of building materials, auto parts, and composite materials used in nuclear power plants.
