Investment casting manufacturing

Investment casting production of the first step is to create investment casting, casting is used to form type refractory shell cavity model, so to get high dimensional accuracy and surface finish of the casting, the first casting itself should have high dimensional accuracy and surface finish. In addition, the performance of the casting itself should also make the next system shell process such as simple as possible. Moudle to obtain the high quality requirements, in addition to should have good molding (pressing casting mold), must also choose the appropriate molding materials (hereinafter referred to as materials) and the proper molding process.
