Investment Casting
Also known as lost wax and precision casting, is based on surrounding an expendable pattern, typically pattern wax, in a ceramic mould and then removing (by melting or vaporizing) the pattern prior to pouring molten alloy into the mould.
- A guide as to the surface finish that is achievable using different casting techniques is shown below (the solid area shows the normal limits achievable using these techniques).
