ABSTRACT:
A manufacturing apparatus of composite filter used as a bead core filter for preventing an electomagneric interference. Particularly, it comprises an element pre-heating section for pre-heating the element through the heaters by conveying vertically the filter element by top and bottom rollers, a coating element coating section for guiding the pre-heated filter element through a guide shaft and passing through a top of the powder disher whereby coating by soaking to the coating agent, and a hardening section for passing in a wave form so as to harden the filter element finished the coating. According to this, not only an influence of the coating agent of the composite filter element is minimized so that each element maintains mutually same electromagnetic characteristics, but also a mechanical strength of the filter element according to the coating of the powder is improved and a coating operation of precise thickness can be executed, and a process line in case of manufacturing the composite filter element is made to be vertical, and the coating process by a coating device is minimized whereby a length of whole lines can be remarkably decreased, and according to this, a workability and a productivity can be improved.
