Line Balancing for Sewing Leather Assembly for Covering Car Seats

Abstract

This study is to use the line-balancing method to solve problems of sewing assembly for covering car seats. The Front Seat Cushion (FSC) assembly, series Volvo S80 Std was studied; it was found that the efficiency of production line was 45.54%. Theories of line-balancing methods and computer software were used to find a solution and select a suitable method for implementation in production line. The outcome of the implement was the efficiency increased by 88.8% and production rate increased from 175 pieces to 304 pieces per 8 working hours. The company could consequently reduce the delay of delivery and over time working hours and this study can also be used as a prototype of line-balancing models for other parts and products.
