Preliminary study of the fuel injector assembly capacity

Sammanfattning: In the near future the demand of the XPI fuel injectors of Scania Cummins JV assembled in Södertälje is predicted to increase. To meet this new demand the assembly line needs to increase its capacity. This paper is a preliminary study of how this capacity increment could be carried out to meet a future demand of 50% higher than today. The assembly line is semi-automated and consists of eight stations in which 100 operators are working in two shifts. The study includes situational analysis, VSM, cycle time analysis, flow analysis, line balancing and optimisation. Each station has been studied separately including all circumstances that can hinder the production of the line. The study shows how a step-by-step ramp up could be carried out for increasing the capacity of the fuel injectors. The suggestions include structural change, layout change, automation, optimisation and program logic changes.
