Investment casting investment casting technology to not only produce small castings, and can produce large castings, the largest size profile Castings nearly 2m, while the minimum wall thickness less than 2mm. While castings have become more sophisticated, in addition to alignment tolerances, the parts can achieve high geometric tolerances. Investment Castings casting surface angle value is also getting smaller and smaller.

Obtained by various casting precision casting different initial investment and productivity are also inconsistent, the ultimate economic benefits are different. Therefore, to achieve more, faster, better and cheaper, they should take account of aspects.
