General castings are relatively rough compared to precision castings and fall within the scope of forging. General casting involves rapidly filling molten metal into a casting solid model at high pressure and high speed, where it solidifies under pressure. However, subsequent precision machining is still required before use. Due to the multiple external forces acting on the casting material, deformation often occurs during the solidification process. General casting is usually suitable for castings where geometric dimensional tolerances and performance requirements for equipment machinery are not high.

Precision casting and general casting are two different casting methods, mainly differing in dimensional accuracy, surface finish, and cost. Precision casting has higher standards and better casting performance. Therefore, consumers can choose castings based on their capabilities and needs when purchasing.
