Investment Casting of Stainless Steel Vacuum Pump Impeller

A vacuum pump is a pump type that removes gas molecules or air particles from a sealed volume in order to achieve difference in pressure creating a partial vacuum. Vacuum Pumps are used in a wide variety of industries and applications to remove air and gas molecules from a process such as the food and beverage industry, semiconductor and electronics industry, pulp and paper, medical, plastics and woodworking and so on.

Vacuum pump impeller, a rotating component equipped with blades, is one of the key components that is inserted into the casing of a vacuum pump. Considering its special structure, it is always produced by stainless steel investment casting.

Stainless Steel Investment Casting Process

Investment Casting of Stainless Steel Vacuum Pump Impeller

For the good corrosion resistance of stainless steel, vacuum pump impeller is always designed and produced by stainless steel investment casting process.

Stainless steel investment casting produces vacuum pump impellers with fine detail and excellent as-cast surface finish. Investment cast stainless steel vacuum pump impellers cast out the blades of vacuum pump impeller directly, and little machining is required, which leads to significant cost savings in material, labor, and machining compared to any other possible manufacturing process.

In investment casting, a detailed wax pattern of the finished vacuum pump impeller is created and mounted onto a wax “tree” that includes the metal delivery system (gates and risers). The tree is alternately dipped into a ceramic slurry and sprinkled with stucco material, and then allowed to dry. This process is repeated until a thick shell exists over the wax pattern.

The wax pattern is then melted, leaving a cavity within the stucco material in the shape of the pattern. Molten stainless steel is poured into this cavity. Once the metal solidifies, the shell is broken away through a shakeout process and the gating material is removed, leaving the finished impeller part.
