Abstract
This thesis is all about Six Sigma methodology. Six Sigma is step by step improving technique for a business growth or to create a new business idea. Six Sigma has two methodology but in this thesis DMAIC methodology was considered because DMAIC methodology is used to improve the existing business operation while other methodology is used to create new aims or goals or new product design. In this thesis DMAIC is used in which first the problem of a company is defined by carrying few interview at the company after that the rejection data was asked. The provided data was measured and thoroughly analyzed for rectifying the main defect and the main root cause for that defect. After identifying & Analyzing the defect and the defect cause as well, the improvising state starts. Few Measures were suggested to minimize the defects also few control actions were suggested to ensure that the quality of product should be maintain and to ensure that all corrective measures were following up regularly. This thesis was done on Injection moulding machine in a factory of Nexus Telecom Private limited located at Chhatarpur, New Delhi. Mentioned Injection moulding machine is used for plastic moulding on RF jumpers used in telecom towers. Objective of this case study was to rectify defect and to suggest corrective measures to minimize those defects occurring in plastic moulding on products. The main defect occurring was crack in moulding & dark black spot in moulding. Barrel & screw were cleaned to increase surface finish of plastic moulding and some training programs were also suggested for the technicians using that machine for moulding.
