Study On Quality Management Improvement Of Automotive Wire Harness Manufacture And Assembly Plant In Company D

With the development of domestic and foreign major automobile groups and the increasingly fierce competition in the market,the demand for auto parts is high demand,high-tech,high-efficiency,high-quality and low-cost.Suppliers also bring huge challenges.The development of Company D in China is an increase in new projects,stricter requirements,increased recruitment difficulties,etc.,which makes the product quality performance slightly fluctuate,and customer feedback problems increase slightly,so how to proceed according to the quality problems of existing products Analysis and improvement to ensure the provision of stable,high-quality products for customers has become a research topic of practical significance.In the traditional quality improvement field,we focus on solving individual problems.In the face of overall improvement,there is a lack of systematic methods.Especially in this kind of labor-intensive wire harness manufacturing enterprises,it is difficult to propose an effective method model.As a whole improvement,this paper is devoted to exploring a feasible and systematic analysis method in the face of complex quality problems,solving the difficulties of complicated operation,complicated process,and affecting many factors,so as to improve product quality.In the analysis of the product status and problems of the wire processing shop of D company,the basic situation analysis was carried out from the equipment,personnel and management methods of the workshop,and the main 8 of the workshop was obtained from the internal and external product quality performance data.The defects and root causes,after determining the proportion of "people,machine,material,law,ring and management" that mainly affect the quality of the product,the "fishbone diagram" method is used to analyze the impact factors of each influencing factor.Finally,the main impact factors were obtained.Through various quality management methods,the main factors affecting the "5M1E" factor were analyzed one by one through process control,error-proof optimization and personnel organization optimization,and a comprehensive and practical Possible improvement measures.Through the research of this paper,a set of systematic methods for analyzing the influencing factors by defect analysis,analyzing the influencing factors from the influencing factors,and then formulating measures from the main factors to improve the overall quality and comparing the quality performance before and after the project implementation are summarized.Satisfaction is increasing,the cost of loss is decreasing month by month,and the overall benefits brought by the project have contributed to the sustainable development of Company D.At the same time,the research also has certain reference significance for other companies.
