... of the methods. There are, however, limitations in some cases. Foundry processes can be classified based on the molding medium, such as sand molds, ceramic molds, and metallic molds. Molding methods may also be classified based on whether the molds are permanent or expendable. Similarly, subclassifications...

..., and accurate, and by using ceramic molds. The ceramic mold segments ( Fig. 8.12 ) are produced from wooden patterns in a proprietary process that maintains good mold accuracy and reproducibility. This mold has a higher cost than the rammed graphite and is also more difficult to separate from the cast parts...

... processes and hot shell cores offer good surface finish. SPM, GPM, LPPM, and counter pressure processes use a coarser ceramic mold coating (as a barrier), prolonging tool life and preventing the mold–metal reaction. The surface finish is grainy.
