ProtoCAM creates wax castings for rapidly-created metal parts. Wax casting can be utilized when multiple metal parts are required quickly, without the need for expensive tooling. This process is typically used for low quantity (10-50) requirements. For less than ten pieces, or for even more rapid turnaround, we recommend checking out our SLA QuickCast service. Wax casting can also be used for low volume production applications where tooling might be expensive and product life cycle may be short, or for high-value, low-volume applications.
Technical Overview of Wax Casting
Wax casting is a process for creating objects, from simple to complex, in a variety of metals by casting an original model or pattern.
To produce our wax castings, ProtoCAM uses stereolithography (SLA) to create a pattern, than produces an RTV (room temperature vulcanization) mold from the pattern. The RTV mold is than utilized to make the wax casting.
After a mold is created, wax casting material is injected into the mold. This allows for near-perfect copies of the original prototype or part to be created. We use vacuum casting technology from Renishaw to produce void-free wax castings.
From the wax casting, metal parts are able to be created. The pattern is dipped in ceramic slurry and then is heated to burn out the wax, creating the cavity used to cast a single metal part. After casting, the ceramic shell is shattered, revealing the part.

Why Choose Wax Casting from ProtoCAM
A high degree of accuracy is maintained in the copy – including the surface finish.
Parts without draft, or with undercuts, can be produced.
Several parts can be created per shift once the mold is complete.
