【摘要】：随着阀门市场的竞争加剧,客户对阀门产品的质量要求越来越严,同时在提高产品质量的同时,不希望成本随之上升。然而质量和成本之间是对立的关系,如何寻找一套合适的质量控制方法,是阀门制造企业十分关注的问题。论文从质量管理的角度出发,通过比对各种质量管理工具优缺点,寻找出适合阀门制造企业进行项目开发的PFMEA工具,并结合阀门产品质量缺陷需进行控制提升这个切入点,运用PFMEA工具给铸造阀门建立项目开发中的质量管理模型,并运用此模型对黄铜铸造阀门进行实证研究。论文提出,以PFMEA质量管理工具作为铸造阀门开发项目的核心工具,建立阀门铸造的质量控制模型,分析查找可能导致铸造阀门产品缺陷的失效因子,进而对这些失效因子进行风险评估,找出对铸造阀门质量起主要作用的失效因子,并进行相应的质量管控,达到控制铸造阀门产品质量的目的。本文的研究结论,可以为阀门制造企业进行阀门铸造质量管理提供实际的指导意义,对其它实体企业进行产品项目开发时的质量管理也有一定的参考作用。
[Abstract]:With the increasing competition in the valve market, customers are demanding more and more strict quality of valve products, and at the same time, they do not want the cost to rise while improving the quality of the valve products. However, the relationship between quality and cost is opposite, how to find a set of suitable quality control methods, valve manufacturing enterprises pay close attention to. From the point of view of quality management, by comparing the advantages and disadvantages of various quality management tools, this paper finds out a PFMEA tool suitable for valve manufacturing enterprises to carry out project development, and combines the valve product quality defects with the need to control and improve the starting point. Using PFMEA tool to establish the quality management model in the development of casting valve, and use this model to carry on the empirical research to the brass casting valve. In this paper, the PFMEA quality management tool is used as the core tool of the casting valve development project, the quality control model of the valve casting is established, and the failure factors that may lead to the defects of the casting valve product are analyzed and searched. Then the risk assessment of these failure factors is carried out to find out the failure factors which play a major role in the quality of cast valves and to control the quality of the cast valves in order to achieve the purpose of controlling the quality of cast valves. The conclusion of this paper can provide practical guidance for valve casting quality management in valve manufacturing enterprises, and can also be a reference for other entity enterprises in product project development.
