Improving Quality of Thin Walled Sand Casting through Selective Quality Improvement MethodsBy R. A. Mehta, M.G. Bhatt
Abstract: Six sigma is a quality improvement methodology. In this research paper, six sigma methodology is used for end shield FG 200 Grey casting of electric body. DEMAIC methodology along with Taguchi method is used to minimize the defect in end shield casting. DOE and analysis for variance techniques are used to determine the correlation of defects with the pouring temperature, pouring time and Si percentage and their optimum values are …

A Review Paper on Minimisation of Sand Casting Defects through Quality Improvement MethodsBy R. A. Mehta, M.G. Bhatt
Abstract: Casting is a process of producing near net–shape metal components. It requires detailed planning, execution and quality inspection to ensure not only the dimensional accuracy of casting parts but the metallurgical integrity and mechanical properties of castings. This paper reviews the different types of casting defects such as shrinkage porosity, cold shut, sand inclusions, mould failure, surface hardening occurring in foundries. These defects directly affect on profitability and quality level …

Application of E-Foundry Based Simulation for the Development of Gating System Design for Endshield FG200 CastingBy R. A. Mehta, M.G. Bhatt
Abstract: Every casting, by virtue of its geometry, shape, basic material, composition and process has an optimal method. Casting should be designed to achieve controlled progressive directional solidification so that it becomes free from solidification related defects particularly shrinkage porosity. In this research project, endshield FG200 grey casting is being simulated using efoundry for the development of new gating system design. This new gating system ensures directional solidification in casting, thus …
