If you have ever wondered which process you can use to achieve a design exhibiting cavities, containing many corrugations or also including undercuts, the answer is investing casting .

 

Even the most complex parts can be produced "from one casting". With special steel materials that are difficult to machine in particular, precision casting offers significant economic advantages. However, the potential to produce complex parts is only advisable if there is corresponding quality in the end result. And it is precisely here that the capabilities of precision casting become clear. High dimensional accuracy, adherence to close tolerances (approx. +/- 0.5% from the nominal size), exact contours and perfect surfaces.

 

We have two major processe:

-lost wax process: use silical gel (for small tolerances, fine surface).
-water glass process: use water glass (for big tolerance, rough surface).
