Abstracts: The project that has been taken up by us is about improving the quality of PVC pipe extruder machinery by solving the problems related to oil seal leakages and welding quality at ASHIRVAD Machinery Ltd .The industry produces PVC pipe extruder machine .The major problems encountered in the machinery are related to poor welding quality of machine structure and oil leakage through oil seal via gear box. Particularly, for repair of oil seal, a large amount of downtime is required and large amount of repairing cost is associated with it. So, our aim is to reduce the frequency of failure due to the above reasons and providing satisfaction to the customer .This project include the identification of the problems, their causes and the possible solutions to the problems. We have adopted a new type of oil seal known as composite oil seal, so that the mean time to repair is reduced considerably and also the life of oil seal increases. So, less amount of failure occurs. We have also suggested some weak point of the industry so that the welding defect cannot be found in machine structure. Our aim is to reduce the failures occurring because of the above problems and providing satisfaction to the customers for their purchase of the machinery.
