Complex Investment Cast “Ball”
Like most MOD contracts, confidentiality is a must.
Finding examples of work that we are allowed to show is therefore very difficult.
What we are showing here is our own version of a series of designs that one such MOD customer commissioned us to do.
The design of this component meant that producing investment waxes via conventional techniques was almost impossible. Utilising the Selective Laser Sintering (SLS) process and Castform PolyStyrene powder was the ideal candidate to produce 75 waxes for investment casting.
In the following sequence of photos you can see de-caking of the parts immediately after the SLS process, followed by the wax infiltration stage.
This de-caking and infiltration process is a very delicate procedure. The material prior to infiltration is extremely weak. Skilled technicians handle the components with extreme caution.
