Analysis And Design Of Quality Control System Of A Key Process Of Polypropylene Film Capacitor

In this paper,we implemented a personalized and convenient quality control system of a key process of polypropylene film capacitor,and based on the basic idea of statistical process control(SPC).With the rapid development of polypropylene film capacitor industry,and constantly improve of the technology and equipment.At the same time,polypropylene film capacitor production efficiency is constantly improving,and the market for the product quality requirements are also gradually improve.It is built a quality control system of a key process of polypropylene film capacitor in this paper.With the concept of 4M1 E,which is Man,Machine,Material,Method and Environments,once anything changes will produce quality fluctuation in the control system.The result of the system is to determine whether a production process quality is under our control in the end.This system is divided into two steps:(1)in combination with the actual production process requirement,to determine the quality of management needs to pay attention to the inspection items and fundamental data.(2)To use the data analysis contained the idea of statistical process control,to determine the quality of process whether is in the steady state combined with the evaluation criteria.This system provide a method fit for statistical process control of a key process of polypropylene film capacitor,and it is based on long-term experience of the polypropylene film capacitor production process quality control in manufacturing site,and combined with the software control.This system is easy to operate.The human factors of interference in the process will be reduces,and the timeliness and authenticity of the data also will be ensure.It can make the management personnel,especially the quality engineer and production management grasp the state of the production process faster and better,in order to respond to the unexpected quality problems quickly,and reduce the occurrence of bad product,decrease the cost of quality.At the same time,the production process can be also moved to an entirely paper-less existence,save the cost of production and management.Finally the competitiveness of enterprises will be increased.The main functions of this system includes user management,component's based data management,data analysis and set evaluation criteria.This system is also a server.You can trace the previous data and the process control conditions,and provide detailed data of design and development,process improvement,after-sales service to management.
