What are the advantages of the more common general castings and precision castings?

As a more refined part, precision casting is used in many manufacturers. The main casting method is to pour the casting metal liquid into a certain mold, and the castings formed after cold violence, precision casting There are many casting processes, 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 may not be reprocessed in the later stage, or only need a small amount of processing. 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. From the current situation, the world's precision casting molding process 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 and closer to component products.

What are the advantages of precision casting compared with common general castings?
Compared with precision castings, general castings are rougher and belong to the scope of forging. Generally, casting needs to quickly fill the molten metal into the casting data model at a high rate under high pressure. Automobile precision castings are solidified under the influence of pressure, and they still need to be put into use after post-finishing treatment. . However, due to the various external forces of casting multiple materials, castings will always be bent during the solidification and molding process. General casting is generally suitable for castings that require low geometric standard tolerances and application performance for equipment machinery.

In fact, casting precision castings and general casting are two different casting methods. The key differences are reflected in dimensional accuracy, surface gloss and market price, but precision casting has higher requirements and casting features are better. Therefore, when customers purchase castings, they can choose according to their own capabilities and actual needs.
