To Reduce Timer Plate Leakage in VE-Mechanical Pumps Using SPC Techniques

Six sigma methodologies DMAIC is very important statical process control technique regarding process improvement, control and productivity improvement in manufacturing industries. In an existing manufacturing process DMAIC, Root cause analysis and ISHIKAWA diagrams are powerful techniques to find out the actual causes which are reducing the productivity. During scrutiny of assembly process of VE- pumps critical parameters, which have major impact on productivity and quality were identified by using ISHIKAWA diagram and actual causes of leakage were resolved by root cause analysis. Thus process can be improved and controlled on the basis of SPC techniques. This paper focusing on the DMAIC technique used to improving the existing handing method at BOSCH, Jaipur plant in the assembly of VE-fuel injection pumps. This paper also integrates with implantation of six sigma to define the maximum safe no. of cycles for test timer plates-312.
