Powder Coating Booth Manufacturers

Powder Coating Booth Manufacturers. We design and manufacture Powder Coating booths with cartridge filters and automatic spray booths. High quality and low price

The powder coating booth is equipment, which is manufactured by welding galvanized or mild steel sheet metals in order to form a closed chamber. The closed chamber here is a vital parameter as the filter unit works with suction. The cartridge filters suck the air inside the powder spray booth by an electrical fan so that the unused powder coating flying inside the booth gets caught and sucked into the filters.

This unused powder coating powder can be reused by the blow-off purge of the filters. The recuperation of the booth is very important as this way you lose so less of the powder coating powder.

Powder coating is increasingly accepted as the preferred finishing process for many applications. Increasingly stringent environmental regulations, rising costs in all areas, and demands by consumers for better quality and more durable products are among the challenges facing today’s finishers. Powder coatings provide a solution to these challenges and others. Powder coating is the technique of applying dry paint to the component.

The powdered paint is normally applied by using a powder feed system and gun to electrostatically charge and spray the powder onto the part. For some applications, the part being coated is dipped into a fluidized bed of powder. The coated part is then heated in an oven, or via infrared panels, to melt and cure the paint. During the curing process, a chemical cross-linking reaction is triggered and it is this chemical reaction that gives the powder coatings many of their desirable properties.
