The improvement of High-Pressure Oil Pipelines Case study : Hiab Choon Trading Co., Ltd.

Abstract

The purpose of this research is to study the process and analyze the cause of the problem and improve the manufacturing process of high pressure oil pipeline. The problem was that cannot produce the 600 pieces per day. The researchers collected data by interviewing the Head of production and inquiring the 10 production staff to study the production process of high pressure water pipe Part no.2669. Then analyzed the causes with the Fishbone Diagram shows that 1) The staff enough to process, the opinion that should improve 6 persons 2) The process, the opinion that should improve 8 persons 3) The machinery equipment, the opinion that should improve 9 persons. Due to the packaging boxes contains much weight to labor in the movement. When working for a long time, the staff were extreme tiredness resulting from fatigue and stopped work suddenly. The researchers use the methods of brainstorming. The results of the brainstorming tool designed to help placing the workers in the workplace. A bar rack size 100x200 cm moving 4 boxes at a time, install Hydrolic levers. The result of improved working methods: reducing procedure, reduction of moving forward, staff work more easily, reducing the process of moving from 5 to just 3 persons to increase production from October to December 2557, the average production for the month accounted for 89.72. After the update, resulting in increased production from February to April 2558, the average was 98.1 increased by 8.45.
