Lost Wax Casting:
It is able to make cast steel valve components, like carbon steel, stainless steel, and other cast steel alloys. Lost wax casting is a precision casting method for valve components, so we can achieve good dimensions and tolerances, smoother surface. Stainless steel valve casting parts are widely used in silical sol casting process, which is another lost wax method. We can use this casting process for butterfly valves, ball valves, ect.
Lost Foam Casting:
This casting method is more suitable for making precison cast iron valve parts, which can also get good surface finish and sizes, such net shape or near net shape valve castings will need no machining or just little machining allowance.
Sand Casting:
Also a casting process for valve casting parts. Sand casting is suitable for both steel and iron valve castings. Compare with lost foam and lost wax castings, it is more suitable to make larger valve components, so normally, we will need to leave more machining allowance for further machining operation. The max weight we can cast is around 2 tons per piece.
