Abstract:

To reduce rubber short and crack problem of Bellow Rack and bellow spin for car model in injection molding machine. This problem definition was studied over a six – month period and included an analysis of production yield and manufacturing costs. Rejection PPM of Molding shop is 34,634 PPM for the year 14~15 (June-14 to Mar-15) against budgeted target of 15,000 PPM. This Manufacturing unit is involved in processing of different parte i.e. Bellow and spin, Air Cleaners, Mufflers and other type of rubber products. As per rejection trend bellow and spin was on top. It consists of different types of defects like rubber short, crack, air bubble, cut mark and shrinkage etc. It was noticed that Rubber short and crack having 80% of the overall rejection facing on the production line and major pain area for selection of the problem.
