Abstract: Process and apparatus for forming a plastic coating on a metal strip. A metal strip is cleaned, surface treated, coated with an electrostatically charged plastic powder in an enclosed chamber using a plurality of spray guns positioned on both sides of the strip, inductively heated to above the melting point of the powder, and maintained in an infrared heater until the fused powder is flowed into a coating having a smooth surface and a uniform thickness. Thermoplastic and thermosetting coatings, having thicknesses of at least 10 microns formed using total induction and infrared heating times of less than 60 seconds, can be fabricated without cracking.
