Baoding GuokunInvestment castingstainless steel pump impeller's steps:

1. Patterns Makings: Creating awax mold of the desired stainless steel pump impellers, and then adding sprues to the wax model to create atree-like structure.
2. Shell Building: Coating the wax pattern with alayer of fire-resistant paint, and then to be sprinkled with sand, so after aperiod of hardening, the surface will form alayer of fire-resistant thin shell.
3. Dewaxing: Removing the wax, the shell is placed into an oven, melting the wax so that it can run out of the shell.
4. Pouring: Pouring the molten stainless steel into the shell, and waiting for solidification under room temperature.
5. Post treatment: After cooling, knock the shell and cut the sprue gate by grinding machinery to achieve net shape impeller castings. Then shot blasting to move mill scales to assure the smooth casting surface.
