Why Are Powder Coating Booth Developed?

A powder coating spray booth is an enclosure developed to contain the powder application procedure. A recovery system is connected to the powder booth shell. The recovery system utilizes a fan to pull air into the booth and prevent the powder that is over-sprayed from migrating out of the enclosure.

The easiest powder coating booth is developed for a single operator to manually apply powder to a stationary product. Other powder booths are designed to transmit parts through the enclosure. Conveyorized systems may be developed for an automatic application, manual application from two sides, or a combination of both, depending on the system's needs. The particular size, style, and number of powder booths required are related to the available space, product size, the amount of capital, and the volume of products to be covered.

Powder coating spray booth shells are made of painted steel, but more powder-coating booths frequently are made of polypropylene, stainless steel, polycarbonate, or other clear plastic, and a few are made of polyethylene or glass or sheet. Painted steel is good, but there is some danger that the paint will chip off and degrade the over-sprayed powder in the reclaim system. Moreover, stainless steel makes a durable booth shell with a smooth surface. 

While the plastic-walled Powder Coating Booth and Oven offers a simple, clean surface, the walls can enable light to penetrate the spray area and help smoothen the process. In addition, a non-conductive plastic walled booth will accumulate less charged powder on the walls. It implies that they can be simpler to clean. It also means that they don't attract as much powder that might be attracted to the part, so they give a modest modification in transfer efficiency.

The part size will affect the width and height of the Powder Coating Curing Oven and the required product opening. The opening size should allow the part to enter with proper clearance around the rims. Mostly, the clearance is 6″ between the biggest factor and the edges of the opening. In a conveyorized system, the powder booth shell should extend at least 18″ above the opening to maintain the hook site above the spray zone. The number of openings in the powder booth will specify powder containment air requirements.

The collector fan is developed to provide 100-120 lineal feet per minute of air velocity all over the openings to contain the over-sprayed powder. Moreover, the powder booth must be designed with enough ventilation to keep the concentration level below fifty percent of the LEL. The number of guns and nominal output per gun determines concentration.
