Efficiency Improvement in Automotive Parts Manufacturing Process by Work Improvement Techniques

Abstract

The objectives of this project were to: 1) study the working process, 2) explore the problems and wastes, and 3) set a standard for working in the process of convex pressing in the pump production line. The case study factory in this research was an automobile parts factory in Nonthaburi Province. Initially, the production process was studied to find out which process failed to produce as planned. The problem was then analyzed by brainstorming with why- why analysis. It was found that the pre-production process of convex pressing took too much time resulting in inefficiency in production as planned. Then, the procedure was improved by using the ECRS technique and the working process was standardized in a work instruction format.

After the improvement, the convex pressing pre-production process was reduced from 15 steps to 11 steps. The motion distance was shortened from 35 meters to 12 meters or 65.70 percent and the preparation time of 20 minutes was reduced to 7 minutes or 65 percent.
