HOW IT WORKS

Prototype Casting Process

SLS Pattern Creation

The first step in the prototype casting process is to build an SLS pattern directly from a CAD file. This can be completed in just hours without tooling.

No need for tooling

The pattern is then prepared for production by coating the part in wax. From here we use our normal process to create a production quality part.

Wax assembly

Patterns are “wax welded” to a central sprue or cluster to facilitate pouring. Many patterns are attached to sprues for increased efficiency

Shell Building

The assembled prue is then dipped or “invested” in into a ceramic slurry. After draining, the sprue is then coated or “stuccoed” with a fine ceramic sand. This process is repeated several times using progressively coarser grades of ceramic material to “build” sufficient “shell” strength.

De-waxing

The shell built sprue is then de-waxed by rapidly heating in a furnace or autoclave leaving behind the perfect shell cavity.

Preheating shell

The shells are then fired at 1600° to 2000°. This cures the shells interior into smooth, hard and strong ceramic material.

Pouring

The hot sprues are then removed from the furnace and poured immediately. The poured shells are then set aside to cool.

Part Finishing

When cool the shell material is stripped away from the sprue. Parts are then cut from the sprue.
