Description

Heating operations are required for a variety of purposes on a powder-coating line. It is usually accomplished with ovens of various forms selected according to the needs of a particular operation. Heating can remove water remaining from prior operations that would cause trouble if carried to the powder-coating station. Most importantly, heating is used to melt, flow, and cure powdered materials applied at room temperature by electrostatic-spray processes. Thoroughly investigating all aspects of the heating components of a powder finishing line is critical to achieving an efficient, effective, and satisfactory operation that will produce a high-quality product. Many variables must be considered and studied when selecting ovens for the powder-coating line. Of utmost importance are: part size, configuration, mass, material, and temperature limitations; conveyor method, part holder, and line speeds; and powder formulation type, thickness, cure profile, color, gloss, and test for cure.
