Advancements in Paint and Spray Finishing Technologies

Innovations in paint and spray finishing have provided more automation, precision, and efficiency for manufacturers. With new technologies, the finishing process has become more accurate, with faster processing times, and more sustainable. Three innovative technologies have changed the way finishing systems help manufacturers improve finishing processes: electrostatic finishing, conveyors, and robotics. 

Electrostatic Spray Painting
Electrostatic spray painting is used for a variety of products including metal and automotive, door frames and railings, lockers, and more. The technology uses electrically charged particles of paint applied to an object with the opposite electrical charge. This technique adheres paint to the surface of the object, provides uniform coating, and reduces waste. The electrostatic finishes are more effective for parts and surfaces that have corners or edges that need to be covered, as the finish reduces defects, ensures consistency, and limits overspray. With less waste in the process, electrostatic finishing is more environmentally friendly as well. 

Conveyor Systems in Paint and Powder Coating
Conveyor systems are another enhancement used in finishing systems to increase production speed and reduce downtime. The conveyor systems can be customized for each project and integrated with other finishing processes like part preparation or curing ovens. There are a variety of conveyor options based on the type of object or surface being finished. Overhead conveyors are used when finishing all surfaces of an object, belt conveyors are typically used in powder coating for flat parts that can lie on a fixed surface, and pusher conveyors are used for heavy parts where items need to be pushed along a track during the finishing process. Conveyor systems are a vital tool where high production volumes are required, like furniture and metal fabrication or appliances. 

Robotic Applications
Robotic finishing systems have modernized the paint finishing industry, with unmatched precision and flexibility for manufacturers. With programmable capabilities, the paint is applied with more accuracy which reduces defects and ensures consistency. Robotic systems also move faster than manual systems, which increases production for difficult to manage projects that are challenging for operators. There are many industries that benefit from the use of robotic finishing systems. For the aerospace industry, intricate part designs paired with stringent safety requirements need exact precision, as well as in the automotive industry with car bodies and components. In the consumer goods industry, robotics are used for electronics, household appliances, and more.
