Manufacturing Investment Castings for Rotary Lobe Pumps — Our Process
Our investment casting process for rotary lobe pumps combines precision tooling, wax pattern production, ceramic shell formation, metal pouring, heat treatment where required, machining, and final inspection. The process is selected according to the component design, alloy, and specified quality requirements.
- Wax pattern: Wax is injected into precision tooling to create repeatable patterns that reproduce the required component geometry. The patterns are assembled onto a sprue to form a wax pattern tree.
- Shell formation: Wax pattern assemblies are coated with ceramic slurry and stucco in successive layers to build a ceramic shell. Once the shell has reached the required strength, the wax is removed to create the cavity for casting.
- Component Formation: Molten alloy is poured into the prepared ceramic shell under controlled process conditions. After solidification and cooling, the shell is removed and the casting is fettled to remove excess material.
- Heat treatment: Where required, castings undergo heat treatment selected for the alloy and specified mechanical or metallurgical properties.
- CNC machining: CNC machining can be used to finish critical dimensions and mating surfaces to specified dimensional tolerances and surface-finish requirements for precision-machined pump components and casting assemblies.
- Final inspection: Components undergo applicable visual and dimensional inspections. Coordinate measuring machine (CMM) inspection and suitable non-destructive testing methods can be used where required by the component specification.
