Investment Casting

A casting scheme, which is often called “dewaxing casting”, that uses fusible material to make a pattern, on which several layers of refractory material are applied to produce a shaping shell, from which the pattern is melted to obtain an integral casting mold that will be baked at high temperature and can be used for casting via sand filling.

Processing flow:

Processing advantages

1. High precision in size and geometry.

2. High surface coarseness.

3. Be able to produce castings with complicated external forms without limitation to the cast alloy.

Processing disadvantages

1. Complicated procedures and higher cost.

Applications Applicable to produce small parts with complicated contours and high precision, or that cannot be manufactured in other ways, such as blades of turbo engine.
