29. CHARACTERIZATION AND FORMULATION OF WAX COMPOSITION FOR INVESTMENT CASTING PATTERN.
In this study selected natural waxes were blended with other selected synthetic waxes like paraffin wax and microcrystalline wax for the purpose of investment casting. Beeswax, carnauba wax and microcrystalline wax were selected to be blended with paraffin wax at the proportion of; 100%-0%, 80%-20%, 60%-40%, 50%-50%, 40%-60%, 20%-80%, and 0%-100% for each blend. Wax properties like ash content, density, specific gravity, melting point, surface finishing, and shrinkage were...
