THE PRECISION INVESTMENT PROCESS

The precision investment casting process involves making of a disposable wax pattern by injection specially prepared wax into a metal die. The resulting wax patterns are then assembled on to a runner system to form a cluster.

A ceramic shell built to the assembly by application of a series of ceramic slurry (investing) and coatings. Then the ceramic shell mould is de-waxed and fired at a high temperature to sinter. The ceramic mould is then filled with molten metal, which solidifies in the shape of original wax pattern.

After casting has frozen, the ceramic mould is broken away from casting parts. Finally casting parties processed at finishing area to the requirements of the customer.
