What is the dimensional accuracy of stainless steel precision casting?
Stainless steel precision casting has high dimensional accuracy requirements, and in general, it can effectively reach CT4-6. Due to the complex investment casting process in the product, there are many factors that will affect the dimensional accuracy of the casting, such as the deformation of the investment mold. Heating, shrinkage of mold material, etc.
Although the alloy shrinkage rate of stainless steel precision casting and the deformation of its castings in the process of stainless steel precision casting, the dimensional accuracy of ordinary investment castings is relatively high, but it needs to be improved in order to achieve consistency. The casting size and surface quality of stainless steel precision casting are higher than other casting methods, and are more complicated than other casting methods. The castings that are resistant to high temperature and difficult to process during the use of the product can be directly used. Cast by investment casting.
The dimensional accuracy of stainless steel precision casting is generally very accurate, and it mainly depends on how we choose the appropriate accuracy.
