Stainless Steel Casting Flanges

OEM Service Custom stainless steel
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.
Investment Casting Typical steps:
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
