Closed Loop Control of the Coating Thickness in Powder Coating Plants
Alexander Buchmüller

A new measurement and control system allows for full quality control of powder coating thicknesses before curing. In the most advanced version of the system, the booth control unit adjusts the quantity of powder automatically on the basis of the measurements until the coating reaches the required thickness. This avoids the need for safety margins commonly applied to the powder quantity settings in practice and, therefore, reduces powder consumption.
