Electrocoating: Auxiliary/Remote Anode for interior coverage?




Q. An automotive manufacturer has requested the design of an ED system that utilizes an auxiliary anode that is to be remotely mounted inside of a large van. The intent is to provide better throw and film coverage/thickness inside the vehicle.

Our e-coat supplier is skeptical of such a design, mentioning failures in previous applications, but ...

Does any have experience with such a design? What drawbacks do you envision with such a system and how might these be overcome to improve throughput and quality?

A. Hi Mike . Auxiliary anodes are a commonplace in electroplating because the coating is not insulative, so distribution tends to be poor. I don't have hands on experience with auxiliary anodes for electrocoating, but in theory it sounds like they could work fine.

thumbs up sign Thanks Ted! We have a tentative, robotic solution, that travels with the vehicle throughout the electrocoat dip process. I will keep you updated on the progress.
