What’s the best material for a pump impeller?
Stainless steel is the most common pump impellers material because of its anti-corrosive, anti-heat and anti-contamination properties. The Baoding Guokun stainless steel casting pump impellers are made as investment casting process, or lost-wax casting process that results in a significantly improved surface finish & casting tolerance and impeller quality than other sand cast bronze pump impellers.
Baoding Guokun Investment casting stainless steel pump impeller’s steps:
| No. | Steps | Details |
| 1 | Patterns Makings | Creating a wax mold of the desired stainless steel pump impellers, and then adding sprues to the wax model to create a tree-like structure. |
| 2 | Shell Building | Coating the wax pattern with a layer of fire-resistant paint, and then to be sprinkled with sand, so after a period of hardening, the surface will form a layer 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. |
| 6 | Machining | CNC Machining & Balancing |
