Abstract
According to the current scenario in the industry, there is no portable shell moulding machine with low cost. Current available machines in market which produces both job and batch type products. Also to manufacture the shell core is very expensive by using the existing shell moulding machine which is not affordable by the small scale and start-up companies. This paper overcomes the existing problems associated with manufacturing of shell core. Our project consists of components such as DOME (Hollow Semi-circular Cylinder with ends covered with sheets), Pattern (Mild Steel), Insulating material (Asbestos powder) mixed with thermosetting resin (Epoxy). This paper optimizes the current existing machine in many aspects such as reduction in size of the machine, eliminate the use of bulky components, for example compressor, actuator which handles the scope of the metal pattern, ejector pins & Furnace.
The method used for preparing the final shell cores is to pour the mixture of fine silica sand and thermosetting resin in the pattern and heating in dome with the use of heater rods (Clamped inside the dome).
