Comparative analysis of precision castings and general castings

What are the differences between precision castings and general castings in casting production?

Precision castings are castings formed by pouring molten metal into a certain mold and subjecting it to cold treatment. There are many casting processes for precision castings, including metal mold casting, pressure casting, investment casting, lost foam casting, V-casting, and so on.

The castings made by precision casting technology are relatively precise, and can be processed without further processing or with minimal processing in the later stage. At the same time, precision casting can complete the casting of complex shaped and thin thickness castings, not only for small castings, but also for large castings, which can be easily completed.

Generally, castings are relatively rough compared to precision castings and fall within the scope of forging. Generally, casting is the process of rapidly filling a solid casting model with molten metal at a high rate under high pressure, solidifying it under pressure, and requiring subsequent precision machining before it can be put into use.
