Stainless Steel Precision Casting

 Stainless Steel Precision Casting includes material SS301, SS304, SS304L, SS316, SS316L and SS321. Investment casting method for Precision Casting of Stainless Steel can get a good surface finish and precision dimensions, you only make a slight machining to reach your requriement. The unit weight from 10gs to 100kgs.  In wax pattern process, we mix stearic acid and paraffin wax in wax pattern making, as you know, it is better than polyethylene,and the wax deformation is small.     In shell making, we adopt automatic sand-covering production line, which was invented under the guidance of our general manager. The indoor temperature was controlled by air-conditions, keeping the temperature at  24℃±1℃, which can make the Cast Stainless Steel much more stable, the internal tissues much more well-proportioned.  In shell hardening process, we use aluminium chloride to harden the shell. This can make the shell so hard th…
