Pattern Production
STEP 1: PATTERN PRODUCTION – The process begins with production of a one-piece heat-disposable pattern. This pattern is made by injecting wax into a metal die. A pattern is required for each casting. These disposable patterns have the exact geometry of the required finished part, but they are made slightly larger, to compensate for volumetric shrinkage in the pattern production state and during solidification of metal in the ceramic mold.
