The Research On Quality Management Of H Company Based On FMEA

After years of rapid development,China’s auto industry has kept an annual sale of more than 20 million vehicles for many years.However,according to the recall data of defective vehicles released by the national regulatory authorities,the quality of automobile has not been significantly improved with the rapid growth of production and sales,on the contrary,there are frequent serious quality accidents.For many domestic auto parts enterprises,quality problems are still existed,and still rely on post inspection.They lack advanced quality tools to prevent and control quality problems in advance.FMEA is a method based on prevention and control,which analyzes and improves the potential failure mode.It is used to find out the potential failure in product design,production and transportation as soon as possible,and put forward effective improvement scheme as soon as possible,so as to avoid the occurrence of failure or reduce the impact of failure.Through the application and practice of domestic and foreign enterprises,it shows that most of the quality defects can be solved by FMEA analysis method.FMEA can help enterprises effectively reduce the risk of potential product failure,and improve product quality.H company is a manufacturing enterprise of auto parts,and its products are friction pads of passenger car in braking system.With the development of the company,the company’s customers and product types are more and more,and the product development duration is gradually shortened,quality problems are gradually increasing.H company’s quality management is studies by using literature research method,spot investigation method and case analysis method.After analysis of internal scrap,customer complaints,rework and repair of H company,it finds that the company has deficiencies in product design and development,process design and development,equipment management and supplier quality management.There is no effective FMEA analysis in design and development.In the process of design and development,only family FMEA is developed,without classification and refinement.The effect of identifying and solving the potential failure of specific products is very little,and FMEA analysis is not carried out for packaging,transportation,rework and repair.Lack of equipment management and supplier management leads to equipment stability and supplier quality status can not meet the requirements of product quality.The process of product design and development,process design and development,equipment management and supplier management of H company based on FMEA is optimized.Combined with the concept of total quality management,FMEA team composed of multi-functional personnel was established.In the process of product design and development,the family DFMEA was established according to the customer’s product design characteristics,the FMEA of friction material formula was established according to the material characteristics,and the automatic production demand was increased.In the process of design and development,we carry out optimization programs such as setting up subdivided benchmark PFMEA,strengthening the application of error proofing,and strengthening the leadership role.In the aspect of equipment management,through the development of equipment FMEA,analyze the equipment failure and failure mode,and gradually engage in the improvement from post maintenance to preventive control.In the aspect of supplier quality management,through the FMEA analysis of supplier selection process,the risk assessment of suppliers is carried out based on long-term and short-term data from three aspects including quality,delivery and service,so as to achieve the purpose of risk prevention.The aim of the study is to improve the quality management of H company by using FMEA’s concept of prevention and control in advance,reduce the defective loss and cost,and make the products more competitive.The study results provide references to the similar type of auto parts company or other industries.
