“How do I get powder paint to stick to the edges of laser cut mild steel products, other than manually removing the scale before going to paint? “

“Laser cut parts have an inorganic soil (oxide) that is produced along the cut edge. This oxide can be removed by mechanical means (i.e. wire brush, sanding, blasting, etc.) or chemically (pickling). A “time saver” automatic sanding machine can remove the oxide very effectively, without manual intervention. Chemically etching with phosphoric or citrus acid (i.e. pickling) can remove this oxide from the part. This process can also be done automatically.”
