What is the difference between investment castings and general castings?

2023-08-22

Precision castings are castings formed by pouring molten metal into a certain mold and undergoing cold treatment.  There are many casting processes for investment castings, including metal mold casting, pressure casting, investment casting, lost foam casting and V method casting, etc.  The finished castings made by the precision casting process are relatively precise, and there is no need for reprocessing in the later stage, or only a very small amount of processing is required.  At the same time, precision casting can complete the casting of castings with complex shapes and thin thickness, not only the casting of small castings, but also the casting of large castings can be easily completed.  Judging from the current situation, the world's precision casting forming technology is developing rapidly and has a wide range of applications.  In the future, the development trend of investment casting technology is that casting products are getting closer to component products.


Generally, castings are rougher than precision castings and belong to the range of forging.  Generally, casting is to quickly fill the molten metal into the casting solid model at a high rate under high pressure, and make it solidify under pressure, and then it still needs to be put into use after finishing processing in the later stage.  However, due to the various external forces of casting multiple materials, castings often deform during the solidification and molding process.  General casting is usually suitable for castings that do not require high geometric tolerances and performance for equipment machinery.


In fact, precision casting and general casting belong to two different casting methods. The main differences are reflected in dimensional accuracy, surface finish and sales price, but the standard of precision casting is higher and the performance of castings is better.
