Abstract:
This paper narrates a new innovation in lost wax investment casting process. The new innovative technology gives enhanced quality of gold and platinum jewelry at reduced cost. The innovation potentially reduces the process timing and at the same time improves the quality. The concept is based on the quick and efficient removal of carbonized wax and gases generated during casting from the investment mold.

Some of the distinct benefits from this innovative technology are reduced burnout cycle timing, complete removal of carbonized wax from the powder mold, effective removal of gases generated during casting, reduced gas porosity and shrinkage porosity.

The new lost wax investment casting process has effectively removed the reasons of porosity at early cycle of burnout. The innovative way of wax tree making and burnout cycle has reduced the wax investment casting time cycle by 30% with considerable decrease in production loss with improved finish.

BACKGROUND:-
Lost Wax Investment Casting is one of the most versatile processes and widely used for Gold and Platinum jewelry
