  • Method for making an electro-immersion finish by forced circulation of a liquid bath in a tank
    Patent number: 4568438
    Abstract: An improved and substantially contamination free electro-immersion finish is provided on an electrically conductive substrate such as a motor vehicle body. An immersion tank holds an aqueous liquid containing an electrophoretically precipitable resin. The substrate to be coated is immersed in the liquid and transported through the tank. The bath liquid in the lower region of the tank is circulated parallel to the direction of transport of the substrate. The bath liquid in the upper region is circulated opposite to the direction of transport of the substrate. The bath liquid may be recirculated by removing the liquid from the tank at the end of the tank where the substrate is removed from the tank. The bath liquid may be purified by filter units prior to being returned to the tank. A separator, such as a cyclone separator, may be disposed in the liquid recirculation conduit ahead of the filtration units.
