Zpracování FMEA procesu vstřikování krycích skel zadních skupinových svítilen

Abstract

The aim of this diploma thesis is application of the method FMEA (Failure Mode and Effect Analysis) to injection molding process of cover glasses of rear group lamps of PMMA (polymethylmethacrylate) in the company Hella Autotechnik Nova, s.r.o. The theoretic part is dedicate to problems of prevention of defects, to description of the FMEA method, to description of procedure FMEA proces, to plastics distribution and to theoretical description of injection molding process. In the practical part is made use of the method FMEA on the function process of injection molding of cover glasses of rear group lamps. The application of the method FMEA was made on the whole process, which begins with the storage of input material and ends with the packaging of finished products. The outcome of the practical part was the identification of possible failures and their causes, and suggestions of convenient arrangements to make the process better.
