With the globalization of market competition intensified, the quality of an enterprise's survival and development, has become an eternal topic. Therefore, China's accession to the WTO, the domestic automotive OEMs and parts manufacturers in order to better adapt to the new international market environment regarded product quality as a \Parts enterprises especially in the face of large foreign OEMs increasingly picky on quality and price, as well as the trend of global sourcing, but also to work hard in the quality, trying to find their own living space. This paper is ideological guidance to improve product quality, combined Dongan Hydraulic Co., Ltd. auto parts product quality problems, quality improvement research. Dongan hydraulic Limited implementation of TS16949 quality management system, but the business is still in the exploration process, the quality of management level is not high. Especially in the process of improvement in product quality, lack of TS16949 quality tools to use to solve the problem of product quality, often based on past experience in handling problems, easily lead to quality problems from happening again. Therefore study based on TS16949-based product quality improvement, quality problems can not only solve the the Dongan hydraulic Limited car parts, at the same time can improve the ability of the Dongan hydraulic employees use of quality tools. Of access to a large amount of literature, master and international quality management theory, dynamic applications; through a survey of the status quo of the quality of products of the Dongan hydraulic car parts, the company's automotive parts products exist, and the actual product quality problems to improve Finally the the Dongan hydraulic future quality control measures. The course of the study, seeks to combine theory with practice. Use of TS16949 quality management tools and theories, including statistical process control methods, including the use of the tools of control charts; Process Failure Mode and Effects Analysis; process capability analysis; measurement systems analysis. Enhance reverse gear shift arm, enterprises and customers a win-win result, the effective use of quality methods for the Dongan hydraulic implement TS16949 quality management system is an important reference significance. In the course of the study, the main results are: (1) The study analyzed the status quo of the Dongan Hydraulic Co., Ltd. auto parts product quality, found reverse gear shift arm there is a serious quality problems. Through the analysis of the quality problems of the reverse gear shift arm at the same time found that the impact of key process quality reverse gear shift arm, through key process control charts, process capability analysis, draw the process capability of the process is a serious shortage. (2) In the course of the study, in the measurement system analysis improve before the process capability analysis and improved process capability analysis using a sample survey methods, sampling methods in accordance with the quality management methods, we get close to the production data of the actual product quality, reliability analysis of quality problems. (3) to analyze the issue of quality, the first analysis of the gage of quality problems, system analysis to determine by measuring gages measurement stage is acceptable; then by the potential failure mode and effects analysis, fishbone diagram analysis to determine The key factor in the impact of the key process quality problems. (4) that the key factor to improve, and analysis by improved control charts, process capability analysis and improvement process to improve the process capability, control measures for quality management Dongan hydraulic Limited .
