Intelligent Controls for a Repeatable, Defect-Free Process.

Finishing wood products requires specialized spraying equipment due to the nature of the substrate and the coatings used. The application is often done on a "flatline" system, where parts move on a flat belt conveyor. The spray guns are typically mounted on a reciprocator that moves back and forth over the conveyor. Because wood coatings often cure very quickly, the fluid delivery systems must be designed to handle catalyzed or fast-flashing materials. Most critically, the curing part of the spraying equipment is often an infrared (IR) or ultraviolet (UV) oven, which can cure the coatings in minutes or even seconds with minimal heat, preventing damage to the wood.

A complete industrial spraying equipment system is more than just the gun. The key components are: 1. A Fluid Handling System (Paint Kitchen): Includes pumps, agitators, heaters, and regulators to deliver paint at the perfect condition. 2. The Applicator: The spray gun itself, which can be manual or mounted on a robot. 3. The Spray Booth: A ventilated, well-lit enclosure to contain overspray and provide a clean environment. 4. A Conveyor System: To move parts consistently past the applicators. 5. A Curing System: An oven or other technology to dry and harden the paint. A turnkey provider like TIMS COATING engineers all these components to work in perfect harmony.

This is a common myth that is no longer true. While you cannot directly charge water, modern electrostatic spraying equipment for water-based paints works through a method called isolation. The entire fluid handling system—the pump, hoses, and the gun itself—is isolated from electrical ground. The system then charges the entire paint supply to a high negative voltage. As the paint is atomized, the charged droplets are drawn to the grounded part just like a solvent-based system. TIMS COATING can provide expertly designed electrostatic spraying equipment that allows you to get the high transfer efficiency of electrostatics with the environmental benefits of water-based coatings.

The choice between airless and air-assisted airless spraying equipment depends on your need for speed versus quality. Airless spraying uses very high fluid pressure (up to 3000 PSI) to atomize the paint. It is very fast and can handle heavy, thick coatings, making it great for protective coatings on large structural steel. However, the finish quality can be rough. Air-assisted airless is a hybrid system. It uses a lower fluid pressure and adds a small amount of compressed air at the nozzle cap. This "shaping air" helps to create a finer atomization and a softer, more controlled spray pattern. It is the preferred choice when you need a high-quality, decorative finish but still want to spray at a high production speed.
