DRAG-OUT REDUCING SYSTEM AND METHOD FOR REDUCING DRAG-OUT

摘要

The present invention is a drag-out bath having a bottom surface, the discharge opening and the upper face is opened, and; Chemical resistance absorbent for absorbing a plating liquid or chemicals deposited on the surface be plated material; It provides a reduction of drag-out system including a; and a support for supporting the absorber from the surface of the absorption body. According to this system, in a pre-processing step, led gold process, followed by a metal surface treatment process comprising a step, etc., including pickling, such as degreasing, alkali treatment, the blood-coated material after one of the steps in the individual process steps chemical resistance to bury the plating liquid or chemicals from the surface and absorbed by the absorbent body and returned to the drag-out bath thereby significantly reducing the drag-out and drag-in.
