stainless steel precision investment casting
Stainless steel precision investment casting is a casting process with little or no cutting and is an excellent process technology in the foundry industry. It is widely used, not only for casting of various types and various alloys, but also for producing castings with higher dimensional accuracy and surface quality than other casting methods. Even castings that are difficult to cast by other casting methods, which are difficult to mold, are not easily processed, can be cast by investment casting.

Because stainless steel precision investment casting shrinks much more than cast iron, in order to prevent shrinkage and shrinkage defects in castings, most of the casting process uses risers, cold irons and subsidies to achieve sequential solidification.
In order to prevent shrinkage, porosity and crack defects in stainless steel castings, the wall thickness should be uniform to avoid sharp corners and right angle structures.
Sawdust is added to the molding sand for molding, coke is added to the core, and hollow core and oil sand core are used to improve the retractability and gas permeability of the sand or core.
