Intensification of Mechanical Properties of the Investment Shell Using Camphor

  Khyati Tamta,  D. Benny Karunakar

Investment casting process has been a widely used process for centuries. It is known for its ability to produce components of complex shapes with dimensional accuracy and excellent surface finish. Investment casting has been used to make manufacture weapons, jewellery and art castings during the ancient civilization and today it is used to manufacture engineering components. In Investment casting wax patterns are made by wax injection and then coating of the wax patterns are done by ceramic slurry, made with silica flour and binder. After dewaxing and firing molten metal is poured in the shell and solidified casting can be achieved. Investment casting can be cast any ferrous and non ferrous metal which is difficult in die casting. Finishing operations are negligible and very thin sections as.75mm can also be cast which is not possible in sand casting but there are many challenges in Investment casting. Shell prepared by conventional investment casting method has very low mechanical properties which is very important for making heavy products. In the present work mechanical properties of the shell can be increase by addition of mixture of Camphor. It will increase mechanical properties like mould thickness, flexural strength, adjusted fracture load and plate weight of the shell.
