Metal spraying is a key process of the manufacture of metalized film capacitors.The quality of metal spraying would affect directly the performance and the life of capacitors.Such aspects of gun height

particles and compressor air etc are studied based on the working principle of the metal spraying machine

and the methods of improving metal spraying quality is given.The improvement result through experiments and batch production are verified.It is proved by the fact that this improvement of metal spraying process has greatly improved the pulse current handling capacity of capacitors

saved spraying material and reduced the cost.
