Before we dive deeper and get to know the advantages and disadvantages of the investment casting, let’s revive a bit of our understanding of the process of investment casting. Investment casting is a widely and commonly used practice to produce and remake identical metal parts with complete precision by using a wax pattern and then pouring hot metal in liquid form into the wax pattern. Here’s a brief description of the investment casting process followed by a brief mention of the advantages and disadvantages of this process. Investment Casting Method The process of investment casting uses expendable wax patterns. For the process of investment casting, first and foremost, wax patterns are prepared. These wax patterns are mostly prepared by injection molding technology. In the cavity, that’s similar to the desired cast part. Then wax patterns are attached to a gating system (a set of channels) through which molten metal will flow and fill the mold cavity. Shell building is the next stag...

Investment casting is also known as lost-wax casting. It’s a process used by investment casting manufacturers in which a duplicate metal sculpture is made from an original sculpture. Intricate designs and work can be achieved through investment casting. Wax pouring and removal After the mould making is done hot melted wax is poured in the cast to create an inner lining to form an even coating. The hollow wax copy is removed from the mould. Chasing and spruing The hollow wax copy is then chased. In this process, a hot metal tool is used to even out any marks left and the wax is dressed to hide any imperfections to prepare the final finished look. Now, the wax looks like a finished piece. After this, the wax copy is sprued with a tree-like structure that’s meant to provide a path for the air to escape and the molten material to flow. Slurry A sprued wax copy is dipped into the slurry of silica and then sand-like stucco. The shell is prepared and allowed to dry. This process is repeated t...
