Abstract
Systems and methods are provided for coating interior surfaces of products with coating material. The systems and methods can include at least one plug to selectively close an opening of the product, wherein the plug is movable relative to the opening between a first position in which the plug is retracted from the opening and a second position in which the plug is engaged with the opening to seal the opening. When the plug is in the second position, a pump delivers coating material to the cavity of the product via a fluid line and a port in the plug. The coating material can fill the cavity, and an electrode can be energized to coat the interior surface of the product with an electrophoretic deposition process. Other coating processes can also be used in a similar manner.
