Casting Pump body

详情

We Offer Casting Pump Body, pump casings, impeller castings, pump mounting brackets. And other pump castings used in oil field, oil extraction, oil refining, petrochemical industry, water treatment industry, solid waste treatment, concrete construction and other industries.
We can use various metal materials according to customer's needs. Such as heat-resistant stainless steel, cast iron, gray cast iron or other alloy steels.
The investment casting process begins with a precise model (pattern) of the end product. For centuries this pattern has been made out of wax, however currently there are a variety of materials that are used. The model is then covered with a ceramic slurry which hardens to create a mold. The original model is then dissolved (for example, wax is melted and drained), and molten metal is inserted in its place. Once cooled and the mold removed (divested), you are left with the finished piece.
In practice, modern Investment Casting is a more sophisticated process that involves many more steps than described above. Sometimes it requires multiple model components, various modeling materials, etc., and like die casting, when done well, the resulting surface quality is excellent.
Typical steps in Investment Casting:
Create an aluminum mold (negative pattern)
Wax injection (positive pattern)
Assembly of the pattern tree (potentially consisting of multiple patterns)
Covering with refractory clay,
Furnace dewaxing
Pouring of molten metal
Separation from mold
Cutting & fettling
Heat treatment
