Coating equipment is used to apply organic, inorganic or metal coatings onto part surfaces for industrial applications. Complete coating systems include all of the necessary components and systems, and may be designed for use in a fixed location. Coating equipment components, subsystems, and replacement parts are also available. Often, coating equipment suppliers provide a variety of coating components. Examples include applicators and guns, booths and rooms, cabinets and hoods, dip tanks and pans, drying and curing units, feeding and metering units, gas controls and regulators, hoppers and tanks, integral process controllers, metrology units and film monitors, pumps, compressors, robotic arms, separators, spray cups, production tunnels, and vacuum pumps. Some coating equipment is manually-controlled or designed for batch operations. Other coating systems can operate continuously, with little or no operator involvement.
