What is the difference between precision casting parts and general casting parts
In casting production, we often hear about precision casting. What is the difference between precision castings and general castings? Below, we will briefly share some specific differences.
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.
From the current situation, the world's precision casting forming process is developing rapidly and has a wide range of applications. In the future, the development trend of precision casting technology is that casting products are increasingly close to component products.
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. However, due to the multiple materials and external forces involved in casting, deformation often occurs during the solidification process of castings.
General casting is usually suitable for castings that do not require high geometric tolerance and performance requirements for equipment machinery use.
In fact, precision casting and general casting belong to two different casting methods, with the main differences reflected in dimensional accuracy, surface finish, and sales price. However, precision casting has higher standards and better performance of castings. Therefore, when consumers purchase casting parts, they can choose according to their own abilities and needs.
