Spray or coating booths refer to enclosures used to perform spray-coating processes. Some of spray-coating processes that can be performed inside the booth include thermal spraying, powder coating, and painting among other deposit methods. The product is made up of various parts, including tunnels, hoods, and cabinets among others. Each part has a specific role in the whole unit.
Presently, these systems exist in different models. Spray booths and rooms are among the most common types. Both are applicable in processing huge work pieces. The painting or coating machine, the operator, and work piece can be accommodated inside the rooms. Booths have recovery systems, internal ventilation, and lighting. The operator may operate the gun employed in offhand mode. Guns are reciprocator-mounted in other situations.
Processing big work pieces also require huge rooms or booths, hence such units are normally big in size. But, for smaller units are used to process small work pieces. As such, paint spray hoods, open-faced booth, and coating cabinets are used. These systems are designed small meaning that only smaller coating equipment and work pieces can fit in. They cannot accommodate the operator. They are mostly used in small scale businesses for handling small pieces of work.
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.
