Application Of Six Sigma DMAIC In The Quality Improvement Of M Product Of J Company

Along with the social economy and the rapid development of science and technology,competition in the market environment is also follow the change,from the competition pattern of a single pursuit of quantity and price to quality and brand competition.In the past ten years,each big EMS(electronics manufacturing services)companies are how to win customers,win the orders,how to create more profits,the ingenious methods,introducing new technology and new methods,enhance competitiveness in terms of quality,cost,efficiency.J company is one of the electronic contract in southern China,it is the laser printer manufacturing contract factory of H company.Laser printers are main production assembly process automatic documents feeding device component assembly,scanner component assembly,final assembly,functional testing,and loading accessory.M project products of the J company is a new generation of commercial laser printers,H is the company's flagship product.For M project in functional pass rate is too low,customer complaint the product output can not meet customer demand.At the same time,a large number of products rework,maintenance,has increased the cost of manufacture.J company by the team to collect the voice of the customer,by Perato analysis the function of the main causes of poor test platform is copying with white vertical lines,by CTQ affecting the quality of key working procedure is the scanner assembly process.From the production process of each working procedure,in-depth analysis,through the measurement of dust particles,pinpoint specific a few related work station,using the brainstorming to find out,the factors that affect product process smudgy using fishbone diagram,causal matrix,failure mode and effect analysis,measurement analysis tools such as systems analysis,find out the impact platform have the possible causes of white vertical lines,copy by DOE validate them and the main problems of team members,the connection between the and suit the remedy to the case,through the dust particles source reduction,environment control production process,assembly process optimization,under the collaboration of all departments and the downstream suppliers,countermeasures on improvement to obtain the very good implementation,and achieved good results.When after the completion of the project,project M product rate from 98% to 99.5%.Reduce the heavy cost of production line,annual savings of up to 960,000 RMB for the company.At the same time also have customer history record QBR score of 93 points.So as to improve the quality of enterprise management level,increase customer satisfaction and loyalty.At the same time for J company provides reference other project quality improvement.
