Stainless steel precision casting requires high dimensional accuracy, which can effectively reach CT4-6 in general. Due to the complex investment casting process in the product, there are many factors that affect the dimensional accuracy of the casting, such as the deformation of the investment and the shell Heating, shrinkage of mold material, etc.
The alloy shrinkage rate of stainless steel precision casting and the deformation of its castings in the process of stainless steel precision casting. Although the dimensional accuracy of ordinary investment castings is relatively high, it needs to be improved in order to achieve consistency. The size and surface quality of stainless steel precision casting castings are higher than other casting methods, and more complicated than other casting methods. The products are resistant to high temperatures during use and are not easy to process. The products can be directly used. Cast by investment casting.
The dimensional accuracy of stainless steel precision casting is generally very accurate, mainly depends on how we choose the appropriate accuracy.
