INVESTIGATING THE EFFECT OF SHAPE FACTOR, SLURRY LAYERS AND POURING TEMPERATURE IN PRECISION INVESTMENT CASTING *Rupinder Singh1 and Jagdeep Singh2 Department of Production Engineering, Guru Nanak Dev Engineering College, Ludhiana (India) 1 rupindersingh78@yahoo.com, 2 c.jagdip@gmail.com Keywords: shape factor, slurry layer, pouring temperature, precision investing casting and taguchi method.
Introduction The precision investment casting process consists of making a disposable wax pattern by injecting wax into a metal mold, building a ceramic shell mold around the wax pattern by the application of a series of ceramic coatings to the wax pattern, de-waxing the ceramic shell mold, and casting the alloy into the shell mold.
The investment casting process has been developed to produce net-shape, superconducting ceramics.
