SS parts

We implement the following steps when creating investment castings:

• Engineering Review. The first step begins with a thorough customer evaluation of the Design for Manufacturing (DFM).

• Mold Design/Build. Once the initial evaluation is complete, we precision-engineer a wax injection mold that can be used to produce wax patterns for the final part.

• Wax Pattern Production. The wax injection mold is brought to the wax room for injection and assembly. This step helps us determine the necessary production capabilities.

• Ceramic Mold Construction. We dip the wax tree into a ceramic slurry until it is completely enveloped in the material. The tree is then thoroughly coated in sand to create a shell that forms the first layer. The mold is then dried.

• De-Waxing. The shell containing the wax pattern is placed into an autoclave that uses steam heat and extremely high pressure to remove the wax.

• Foundry & Pouring. The mold is placed into a high-temperature oven set to approximately 1000 C (1832 F) for curing and to prepare it for accepting molten metal.

• Shell & Casting Removal. Once the metal has cooled, the ceramic mold shell is broken away. At this point, the casting(s) can be removed from the metal tree.

• Finishing. The part’s gate is often removed by machining or grinding after manufacturing. Investment castings utilize a ceramic mold that can produce a much smoother surface (averaging a 125 RA surface finish).
