Precision casting is to pour the liquid metal into the casting mould with the same shape as the parts. When the casting is cooled, our precision casting products can be formed. The casting methods include sand casting, special casting, precision casting and V casting, and precision casting inside casting is a special casting. Parts that are cast in this way do not need to be processed, or require a small amount of processing to be used.
Ordinary casting is boring, die-casting is casting method with pressure casting. At high pressure, the liquid metal is filled into the casting model at a high speed. Let it solidify under pressure. The ordinary casting multi - material external force, in the solidification state deformation.
Precision casting and ordinary casting are two different casting methods, but precision casting requires higher precision and better precision.
