Research On Quality Improvement Of Coating Products Of H Company

Enterprises rely on quality to survive and develop,and with assured quality,enterprises can become more competitive and develop on a constant basis.Excellent quality management can not only improve product quality,decrease cost,and increase efficiency as well as customer experience and satisfaction,but also benefit society.The coating products currently produced by H Company include thermal conductive materials,thermal insulating materials,and thermal dissipation materials,and are mainly applied in electronic products and the new energy industry.Although a constant increase has been observed in the annual order,the reject ratio of products remains high.H Company is now spending expensive funds and time costs in this regard,severely impacting its constant and high-speed development.By regarding non-substrate thermal adhesive coating products of H Company as the research object,this paper firstly elaborates the definition of quality management and quality improvement and then defines the quality improvement method is adopted based on ISO9001 Quality Management System,to provide a solid theoretical foundation for the study on improving the quality of coating products in H Company.Secondly,four key problems that may influence the quality of coating products in H Company are discovered by investigating and analyzing the current quality status of its non-substrate thermal adhesive coating products,i.e.,the problems in the environment,personnel,incoming materials,and equipment.Interview method and the method of direct observation,etc.are adopted to investigate the low reject rate,while reasons causing wrinkles,rubber marks,uneven thickness,lines,white spots,and dirt that will influence the yield of products are further analyzed and summarized by adopting fishbone diagram,attribution method,5WHY method,and brainstorm method,and then corresponding quality improvement plan is designed based on the improvement objective set by benchmarking method,in respect of reasons causing the low yield.Finally,the data before and after the improvement are compared and evaluated to prove that the plan is feasible and effective.In conclusion,the quality improvement plan set forth in the paper can not only provide guidance for H Company to improve the quality of non-substrate thermal adhesive coating products,but also improve the reject ratio of its coating products based on the thoughts applied in quality management,and can be used as references for similar enterprises.
