Aiming at the problems existed in aluminum electrolytic capacitor production equipment, an impregnation pot was designed on the basis of new impregnation method and process requirements. The impregnation method and process requirements of the aluminum electrolytic capacitor were introduced. The feature and function of the impregnation pot were analyzed. The stress and strain distribution was obtained with the help of finite element analysis software. The structure of the pot was optimized. The results indicate that the impregnation pot makes on-line production possible. The elements of capacitor can be impregnated reliably without polluting the guide pins, and the quality of capaci- tor is improved.
