Electrically charged particles can adhere to the electrical surface of the part and remain stuck as long as they retain part of their charge. Recovery and recovery systems can collect and reuse any over pulverization material in future coating applications. Powder coating is a dry finishing process that uses a spray gun to apply electrically charged dust particles to a rectified part. After the part is covered, it is placed in an oven for a high temperature curing process. The curing process causes a chemical reaction that creates an incredibly strong coating that is extremely resistant to decomposition. The powder spray booth is designed to keep the rest of your store clean and provide a well-lit space to apply powder coating.
Commercial fabric cover activities are active in every major city in the United States and worldwide. For the protection of industrial and automotive metals it is difficult to overcome the powder coating because of the toughness and durability. Cities that limit the use of solvent-based paint for air quality reasons accept powder coating activities.
The equipment you need to start a powder coating business includes a powder coating spray booth to coat parts, spray guns to spray over the coating and a curing furnace. The cab must have adequate ventilation and exhaust pipes for safe escape from vapors, according to the Occupational Safety and Health Administration of the United States Department of Labor. Powder coating has been around since the early 1970s and today more than 15 percent of industrial powder coating finishing processes use.
A powder coating gun uses compressed air to blow dust particles along a loaded rod to give them a static charge. The particles adhere to the piece because it is the negative pole of the same electrical circuit. That is the actual powder coating process in a nutshell, apart from the extensive pre-cleaning work on the pieces. The point is that it has a wide variety of powders to choose from, each with different properties. Different powder brands have a very variable quality and different compositions. The Harbor Freight Powder Coating Kit consists of the powder coating spray gun, an in-line filter, dispersion tips, a foot switch, powdered cups, an electric transformer and a ground clip cable. You need an air supply that provides a continuous air pressure of 10 to 15 psi and a capable heat source of 300 to 500 degrees Fahrenheit to heal the coating.
It can be more difficult to get a good layer of items that do not conduct electricity, but as long as they can survive the curing process, you can cover them. All powders heal below 425 degrees F and many heal at altitudes up to 340 degrees, giving you a wide variety of materials.
Regardless of which type of spray booth is added, a powder coating structure must be seamlessly integrated into a production line. This integration is easier with batch booths because they are generally independent and can be used to finish large amounts of products in batches, often made manually by powder gun sprayers.
