IMPROVING THE EFFICIENCY OF THE PRODUCTION PROCESS OF AUTOMOTIVE PART IN ORDER TO REDUCE COST

Abstract

This project aims to reduce cost in production and labor cost to find the way to improve manufacturing process. The corrective action steps begin with a comprehensive study and analysis to identify ways to enhance the production of the PLATE 20Y-06 by using 7 QC Tools, ECRS and Why Why Analysis to analyze the root causes of the problems by finding production cost information, production chart Including designing new production steps and collaborating with the company's engineering departments to develop and test molds.

The research results indicate significant reductions in costs, production time, production steps, and operational procedures for the PLATE 20Y-06 workpiece. By implementing the 7 QC Tools, ECRS, and Why Why Analysis then costs were reduced from 149.68 THB per unit to 107.65 THB per unit resulting in a cost reduction of 42.03 THB. Production time has decreased from 21.35 minutes per unit to 14.88 minutes per unit and the production process has been streamlined from the original 7 steps to just 4 steps.
