Research on Improving the Pass Yield of the Manufacturing of 0645 Type of Sharpener

Abstract

With the rapid development of stationery industry, it is very important to improve the pass yield of manufacturing of pencil sharpener, a kind of traditional stationery products. The current situation of manufacturing process of 0645 pencil sharpener was investigated first. The goal of quality analysis and improvement was set. The causes that affect the main quality characteristic index were analyzed by the cause and effect diagram, and the main causes were confirmed. Design of Experiment (DOE) technology was used to find out the best process conditions. Then countermeasures were made according to the main causes. After checking the improving effect, It is found that the pass yield of the manufacturing of 0645 sharpener has increased from 89.1% to 95.2%.
