Investment casting is widely known as lost wax investment casting and one of the best precision casting process used for fabricated metal parts for any types of alloy. In past investment casting widely used for complex component manufacturing.
Investment casting process start with fabrication of a sacrificial pattern with basic geometrical shape for finished cast part. Generally this patterns are made by investment casting wax and injected into metal wax die. When wax pattern is designed then its assembled with other metal wax components to form metal delivery system which is known as gate and runner system. Now this whole wax assembly is dipped into ceramic slurry, for dry and this process is repeated until shell of 6 mm is applied.
When ceramic has dried the take entire assembly in steam to remove most of the wax. Then after remain portion of burned wax remove from furnace. Now preheated this mold with specific temperature and pure with molten metal for creating metal casting. When casting is cooled then chipped away mold shell from the casting. Now cuts gates and runners from casting for finishing the casting. This is one of the quick cast processes.
Through investment casting, you can make high quality patterns without cost and time with fabricating injections mold dies. In addition, this pattern fabricated by CAD through which we make complex pattern. As per my way most of casting foundries in India used investment casting for fabricating complex and solid industrial shape while other casting process are time consuming and costly. In addition, you can make small parts through investment casting
