Lost wax cast method

In lost wax method, one model produces one cast part.

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

Finally, the ceramic shell is knock off and the castings are cut from the cluster, heat treated and surface finished to meet customer specifications.

Competitive Advantage:

Lost wax casting is often choosen because:

• difficult shapes can be cast as one part without welding (welds can be finished in wax process)
• parts with counter-relief/inner structures can be cast
• machining costs are reduced to minumum as investment casting provides net-shaped parts
• can be used on almost any alloy.
