Enclosures in which spray-coating processes is performed are known as spraying booths or coating booths. Powder coating, painting, and thermal spraying are examples of some of the deposit processes which are done inside these booths. The units are composed of different parts which include hoods, cabinets, and tunnels among many others. Every component of the unit has a particular role that it plays in the entire system.
There is a huge number of these systems in existence today. Some of the most common ones are spray booths and rooms. They both are used to process large work pieces. Rooms can accommodate the work piece, the operator, and the coating or painting machine. On the other hand, a booth contains internal ventilation, recovery systems, and lighting. The gun used may be operated in offhand mode by the operator. In some cases, guns are reciprocator-mounted.
Spray room and booth are designed to cover huge amount of work and therefore come in large sizes. Smaller systems that are applied on small work pieces exist too. Coating cabinet, open-faced booth, and paint spray hoods are examples of small models. Coating equipment and smaller work pieces alone can be accommodated by these small systems while the operator while the operator works from outside. Therefore, they are applicable in small businesses that process smaller work pieces.
Production tunnels are another variety of these machines. They are created in the shape of a tunnel just as suggested by the name. There are different stations in the tunnel where various tasks are done. Stations for conveying, curing, drying, cleaning, coating and others are examples. Through the tunnel, work pieces are passed down. As the work piece passes down through the tunnel, it is worked on until it emerges from the other end. With that, the work is done at a faster rate in a production plant.
Cabins in which the process happens are normally completely sealed in all directions, including the floor and ceiling. They have two doors, one for the operator and the other for the work piece. When the process in finished, the work piece exits through the same door. There are various designs of these systems, the variations include units with a ceiling and three walls but lacking doors.
Airflow inside these units is achieved through a number of ways. In most cases, air enters the unit through the ceiling where it goes through an air filtration system. The air is then moved vertically into the cabin and may be exited in one of the three main ways available.
The three methods are downdraft exhaust pit design, downdraft exhaust wide-wall, and downdraft exhaust rear-wall design. Each of the methods of removing air can be used but some are more effective than others. Thus, the choice of exhaust method usually determines the final results achieved in the painting or coating process.
The units differ a lot in terms of size. The type of job one is getting the unit for should determine the size of machine to choose. The price also differs, with huge units costing more. Fortunately, the investment can be easily recouped once the system is running and offering services to customers.
