What is the difference between precision castings and general castings in casting production?
Precision casting parts are castings formed by pouring molten metal into a certain mold and undergoing cold treatment. There are many casting processes for precision castings, including metal mold casting, pressure casting, investment casting, lost foam casting, and V-method casting, among others.
The finished castings made by precision casting technology are relatively precise, and can be processed with minimal or no further processing in the later stage. At the same time, precision casting can complete the casting of castings with complex shapes and thinner thicknesses. It can not only be used 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 involves rapidly filling molten metal into a casting solid model at a high rate under high pressure, causing it to solidify under pressure. However, it still requires later precision processing before it can be put into use.
