Background

Die casting is called casting for short, and is a precision forming technology for metal parts close to the final shape and size, and the final product is a die casting. The essence of the method is that under the action of high pressure, liquid metal is filled into a die cavity at high speed, and is formed and solidified under the action of pressure, so that a die casting with clear outline and smooth surface is obtained. In the non-ferrous metal casting industry, die casting is an important casting method. In recent years, light alloys mainly containing magnesium and aluminum have gained importance in the die casting industry, and aluminum alloy castings obtained by die casting account for about six components of the total amount of lead alloy castings.

The semi-solid die casting is a novel die casting method, a die cavity is filled with semi-solid liquid metal, but the semi-solid liquid metal has high viscosity and is difficult to flow, so that the semi-solid liquid metal is one of the characteristics of the semi-solid liquid metal, and the semi-solid liquid metal cannot be efficiently formed in the forming mode at the present stage.
