Research On Reduce Oil Stain Of Chrome Plate By Six Sigma Management

Chrome steel plate at present domestic main application range for beer bottle caps, drinks, neutral food cans of paint cover, make food cans were rare. And the use of foreign countries in print with the none of tin board for fish meat cans, especially two piece cans, give full play to the none of tin board excellent resistance to vulcanization sex and coating adhesion strong advantage.BAO company plating coating factory in2010for the first time introducing chrome plated line, client report product surface exist irregular staining, besmear in Indian appear in the process of leak painting phenomenon. The problem of user feedback, the paper analyzes that the main reason is the strip surface coating the amount of oil is uneven and statistics2010years production conditions, staining defects closed21.32%on average rate, closed on the highest rate of24%, the oil film CPK value is0.3. In order to promote the domestic steel chromium plating in use, first must solve staining defects, improve product corrosion resistance.In this paper, we use the six sigma idea and management method to solve the question. The main contents include:(1) Research actuality oil stain defects,collect data and clear the problems.(2) According to the implementation steps of six sigma to analyze the problem and make for improvement and implement.(3) Evaluate the result of improvement and root improvement measures.After the purpose of study, using the six sigma thought and management, chrome plated product staining defects down to6%, produce economic benefits in3.04million’s year. At the same time, a well-trained project team is formatted, the dissemination of Six Sigma thinking and for the future to further is promoted.
