RESEARCH ON THE GLOSS IMPROVEMENT OF
WATER-BORNE WOOD COATINGS IN Z COMPANY BASED
ON SIX SIGMA MANAGEMENT
ABSTRACT
Six sigma management, which started in MOTOROLA Company, has been adopted by
many enterprises in the world and obtained good economic benefit after many years of
practical application. On the basis of data analysis, it is a kind of management ideas and
methods in order to reduce defects, cost savings and improve customer satisfaction.
Z company group has become the largest wood furniture coatings company in China. As
the waterborne wood coatings leading company, how to guarantee the stability of waterborne
wood coatings product quality and enhance the level of quality of waterborne wood coatings,
especially the gloss qualified rate, has become the main problem. Improving product quality
consistency is the basis of “solvent to water” under the current environmental pressure of
industry. Based on this background, the water-borne wood coatings gloss quality is studied
as a research topic of this paper.
This paper first introduces the background and practical significance of the thesis in the
process of the transformation and upgrading of the products based on the current
environment, also introduces six sigma management and the successful application
experience at home and abroad. The origin and development of six sigma management are
described in detail. The situation and the main problems of the wood coatings industry are
introduced at the same time. The necessity of implementing six sigma management in Z
company is analyzed. Finally by using five stages process improvement method of Define,
Measure, Analyze, Improve and Control, the gloss qualified rate of current Z company
water-borne wood coatings products is improved. In the definition stage, according to
water-borne wood coatings process, the problem of the quality of gloss was identified. The
team of Six Sigma project was established. The high-end flow chart (SIPOC) was used to东华大学工商管理硕士学位论文

identify the problems of the quality. In the measurement stage, the production flow chart and
causal diagram were used to determine the factors that affect the quality of glossiness. Data
collection plan was made and the validity of the measurement system was evaluated by
one-way analysis of variance to ensure the accuracy of the measurement results. In the
analysis stage, the stability and process capability of the production process were analyzed
by using the operation chart and Xbar-S control chart. Finally, the key factors affecting the
glossiness of the water-borne wood coatings were determined by the correlation analysis and
regression analysis. In the improvement stage, it developed solutions for the key factors.
Preliminary test results had reached the expected goal. In the control stage, successful
practices are standardized by optimizing process flows, modifying work instructions and
trainings.
Through the research on the gloss improvement of water-borne wood coatings in Z
company based on six sigma management, the cause of gloss qualified rate is found out, and
put forward the corresponding solutions. The practice of Six Sigma management is proved to
be feasible and effective. The research helps Z company accumulate valuable practices to
develop six sigma activities and elevate its quality management to next level. For the current
supply side reform advocated by the country, the transformation and upgrading of products,
but also for the promotion of private coating enterprises, this paper provides a reference
experience.
