Feinguss casting

Feinguss casting is an industrial process of remaking metal parts while retrieving the intricate details present in the original model. Feinguss casting is commonly referred to as investment casting or lost-wax casting. It’s a widely used process by investment casting manufacturers, to make a duplicate metal model from an original model. The intricate designs and work of an original model are made through the casting process. Feinguss investment casting is like lost-wax casting. The metal casting has been in practice for thousands of years and feinguss casting is among the oldest metalmaking techniques.


Earlier beeswax was used to form the wax pattern but now in modern days, high technology waxes are used to form the wax patterns. The feinguss casting process occurs in the following stepsA wax model that is the replica of the metal part is made. To make the wax model a mold is prepared that is an exact negative of the original wax model. Melted wax is poured in the mold to form its inner lining. This hollow wax copy is then removed from the cast. The wax copy is then sprued with a tree-like structure and this sprued wax copy is dipped in the slurry of silica and sand-like stucco and then it’s allowed to dry. After multiple repetitions, the desired thickness of the shell coating is attained. The shell is allowed to dry and hardened on a kiln. The wax inside the shell is melted to run out. After cooling, the shell is tested with water for cracks. In the case of cracks in the shell, those cracks are filled with a thick paste. After removing the moisture, molten metal is poured in the shell. When the metal gets cooled the shell is then blasted away and the roughcast is obtained. The spurs are cut off and the surface is chased, smoothened, and polished to give it the finished look.
