Lost wax casting process

First, a wax injection machine creates a wax pattern through a wax die. Patterns are then assembled onto a sprue/runner system which carries the pattern through the remainder of the process. Next, successive layers of ceramic and stucco are applied to form a hard shell. The molds are then heated to remove wax inside and placed into a sand bed. From there, molten metal is poured into the hollow mold.

Finally, the ceramic shell is broken off and the lost wax castings are cut away, heat treated and perfected to meet customer specifications. This method ensures each part meets the products' dimensional tolerances.

Competitive Advantage:

The lost wax process is good for casting metals with high melting temperatures that cannot be moulded in plaster or metal.
Parts that are typically made by investment casting method include those with complex geometry such as pump impeller or fire arm components. High temperature applications are also common, which includes parts for the automotive, aircraft, and military industries.
