Content Inside: Kansas Small Business Assistance Program June 2001 1-800-578-8898 1 Metal Finishing Industry P2 Checklist Parts Cleaning: Mechanically preclean parts as much as possible first. Determine level of cleaning needed. Work with the parts supplier to use a corrosion inhibitor more easily removed or compatible with the cleaning system used on site. Arrange for just in time delivery to reduce or eliminate need for corrosion protection. Use a lower vapor pressure cleaner. Use an aqueous cleaner. Reduce Drag Out Losses: Extend drip time; install drip racks. Install drainage boards between tanks to route drag out into the correct process tank. Reduce workpiece withdrawal rate from the chemical bath. Install air knives or water misters to remove drag out. Lower the concentration of plating bath constituents, increase the plating solution temperature. Both actions will reduce solution viscosity to enhance runoff. Rack workpieces being plated so that cavities open downward to promote draining. Use non-ionic wetting agents to reduce solution surface tension. Implement the use of angled barrels. Maintain Chemical Baths: Reduce drag out losses and drag in contaminants. Cover baths when not in use to minimize particle contamination. Establish and maintain bath operational parameters; test and monitor reqularly. Install drag out collection tanks or a static rinse to capture bath chemical for reuse. Filter chemical baths. Use a filter that can be unrolled, cleaned, and reused. Use a bath maintenance technology to â€œcleanâ€ chemical baths of unwanted metals. Remove dropped parts daily. Reduce Rinsewater Use : Reduce chemical drag in by methods listed above. Install multiple rinse tanks in a counter-current series system. Install automatic flow controls, such as flow restrictors or conductivity sensors. Stop rinse water flows when not using the lines, if possible. Agitate the rinsing bath to increase efficiency. Repair leaking tanks, pumps, and valves
