Investment casting

Lost-wax investment process
Wecare Cast Parts uses this process exclusively. Wax is injected into an aluminum die to create a wax “pattern”. These wax patterns are then assembled onto a “tree” which is repeatedly dipped in a ceramic slurry that, after drying, hardens into a mold. The wax is melted out, the mold is preheated and the metal is poured in. The resulting casting has an excellent surface finish of around 125 RMS, crisp lettering and minimal machine stock. This process is perfect for highly visible or highly machined parts. Tolerances can be held to +/-.005” in most cases.

Advantages: excellent overall appearance, machining reduced or eliminated, can cast very   thin walls, good for prototypes, economical tooling costs.
