Explain the difference between precision casting and ordinary casting


Precision casting is to pour liquid metal water into a casting model with the same shape as the part, and after the casting cools, our precision casting products can be formed. Casting methods include sand casting, special casting, precision casting, V method casting, and precision casting in precision casting belongs to special casting. Parts cast in this way do not require machining, or require a small amount of machining to be used.
Ordinary casting is boring, and die casting is a casting method using pressure casting. Liquid metal is filled into the casting mold at a high velocity under high pressure. Let it solidify under pressure. Ordinary casting uses more raw materials and external forces to deform in the solidified state.
Precision casting and ordinary casting are two different casting methods, but precision casting has higher requirements and better precision.
