Application Of DMAIC On K Company Quality Improvement Of The Burr

As a trade war between USA and China,many export enterprises feel double pressure from e tariffs increase and cost down,in order to enhance marketing competitiveness,on one hand,enterprise must be lower the price,on the other hand,further enhance the quality of our products is also reduce the scrap and rework caused by quality problems,namely indirectly reduce the unit price of the products.As to improve the quality,the domestic enterprises mostly continue to use the international standard ISO9001 quality standard system,use quality tools and quality management to improve the quality of the product.At present the most popular and practical is six sigma quality management,more and more domestic enterprises be in the use of six sigma quality management and obtain good effect.In this paper,we take K Company of the furniture hardware industry as an example to research the company how to improve the quality,through the implementation of six sigma management method improve the quality and make customer satisfaction,finally gain the more orders from widely customer.First of all,through research a large number of six sigma related literatures,understand the use of the theory and implementation process,interpretation of the theory of the core content and tools.Secondly,introduce the K Company and its quality control system,illustrates the problems existing in the company’s quality system.The next is to describe the problem on the product and combined with the quality complaint from the customer,it is necessary to us to improve the biggest quality issue of tube’s burr by implementation of six sigma model improved.At last,detailed explain the company how to implement the six sigma DMAIC model,and what result we want to get? Firstly step is defining phase(Definition),using the VOC to identify customer’s needs and concerns,use SIPOC to find the key feature of production process and focus on the improvement on the critical process and parameter.Measuring phase(Measurement),by measuring related data and analyzing measuring system stability.The analysis phase(Analysis)using the fishbone diagram,Plato,and brainstorming to find out the main problems and root cause.Improvement stage(Improvement),based on the rapid improvement,5S onsite management,experimental analysis methods such as improving the influence factors.Controlling phase,formulate the corresponding code of conduct and guidelines(WI)to control and maintain to the good results of improvementThe research of this paper meet the development of modern enterprises,through the K company quality improvement implementation of six sigma DMAIC improvement model,effectively improve the qualification rate of pipe cutting,reduce the rework cost,improve production line pass yield from 95% to 98.5%,the direct economic efficiency is to save cost,1.68 million,at the same time the customer monthly performance in more than 90 points and gain the customer’s praise and affirmation,enhance K company product market competitiveness.In addition,more important is to set up K company six sigma quality culture atmosphere,high-level attention,middle-level support,full staff participation,exercise the whole team work together,provide the help and reference to improve the next project.At the same time,it will be to provide the reference for some small and medium-sized enterprise on quality improvement and using six sigma models.
