Design The contemporary engineer thinks in terms of investment casting.

Wax Molding First, we create a suitable mold for producing a wax pattern to close tolerances. Under pressure, we inject molten wax into the mold cavity.

We then mount these wax patterns with appropriate gates and runners and dip the wax pattern into slurry of investment ceramic investment material and allow it to harden. We repeat this until a tough shell is formed.

Ceramic Molding We then remove the wax form the pattern material by heating the ceramic mold in a high-temperature furnace. The material is lost. Next pour molten metal into the ceramic mold.

After solidification, the metal parts are removed from the investment material. Each lot is inspected for quality to insure complete satisfaction. The final product is an intricate lost wax investment casting with close dimensional accuracy, sound structure, and fine surface finish.
