sumangal casting | Investment Casting | Stainless Steel Investment Casting | Lost Wax Castings

  Investment casting  is in a lot of ways similar to lost-wax casting and it is an old metal making process to duplicate the features of the original sculpture and then cast multiple identical metal parts that are an identical match to the sample metal part. Intricate detailing and designing are achieved successfully through the process. An original wax model similar to the sample metal part is made and then mild making is required. An outer rigid mild is prepared by dipping the wax pattern in ceramic slurry plus sand-like stucco. Dipping in the slurry is repeated multiple times to attain the desired thickness of the shell. This outer mild is the exact negative of the original wax pattern. This wax and mild assembly are spruced with a tree-like structure. The shell-coated wax assembly gets hardened and then the wax is melted out of it by heating the assembly. ​The shell is cooled and tested to check if it contains any cracks in it, the cracks are filled with a thick paste.
