Suitable materials for die casting: cast iron, cast copper, aluminum alloy, zinc alloy, magnesium alloy
Principle: A method of using high pressure to press liquid metal into a mold, and obtaining a product after crystallization and cooling.
The die-casting process requires processes such as raw material smelting, die-casting molding, slag removal, and surface treatment. Die-casting is because high-temperature liquid metal enters the mold cavity to solidify and form. The metal liquid that first enters the mold cavity is likely to oxidize with oxygen in the air and affect product quality. Therefore, die-casting molds will design slag bags to store these products. Oxidized slag.
As you can see from the above picture, the nozzle and the slag bag occupy a considerable part. After the die casting is out of the mold, it also needs to go through the water outlet and slag ladle process. Usually, the surface needs to be polished, polished, sandblasted and mechanically processed according to the product requirements, and finally needs to be surface treated. The water outlet, slag material, and polished parts will have some influence on the consistency of the product, and attention should be paid to products with high product appearance and size requirements.
