Abstract

Sand casting is the most common technique used around the world. Founding or casting is one of the oldest manufacturing processes, which dates back of approximately 4000 BC. The most likely occurring defects in casting can be found out by different techniques. Inspection of castings aims at finding both surface and subsurface in casting. Inspection will ascertain the quality of castings and result in their acceptance or rejection. Foundries try to reduce rejection by experimenting with process parameters or modifying method and tooling design which reduces the quality of casings and increase cost of production. The project titled “Application of FMEA Technique in sand casting for reduced rejection rate” is aimed at reducing rejection rate of castings in an Indian foundry. The overall output of the project proposed here in is to reduce the casting rejection rate using FMEA model. This paper deals with a case study on a cylinder frame, which is having high rejection rate in an Indian foundry is taken and the defects of casting are solved using the proposed FMEA technique
