Automatic Powder Coating Booths

The automatic powder coating booth is designed for automatic lines, where there is a conveyorized line carrying the parts into the booth. The booth has openings from each side for the reciprocators and can also have painter posts where the painter can stand with his manual powder coating gun and correct the unpainted parts (if there are any – this depends on the geometry difficulty) for better finishing.

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.

Automatic powder coating booths are equipped with cyclons and an after filter group, dedicated to filtering the powder particles flying through the Cylon into the exhaust box.

Cyclon is cone-shaped equipment, where the air with flying powder particles is flying in from the upside part and circulates inside and this circulation of air helps the heavy particles (such as powder particles) to settle and sit down the cyclone and gets transferred to the powder coating booth back by a powder injector. This powder coating injector works with the venturi principle and operates with compressed air.

Production of the automatic powder coating booth

The production of an automatic powder coating booth is a complex process that involves a variety of steps. Here is a general overview of the process:

1. Design and Engineering

The first step in the production of an automatic powder coating booth is to design the booth. This involves creating a detailed plan that specifies the dimensions of the booth, the location of the various components, and the materials that will be used. The design must take into account the specific needs of the customer, such as the type of parts to be coated, the volume of parts to be coated, and the desired finish.

2. Fabrication

Once the design is complete, the booth is fabricated. This involves cutting and welding the metal components of the booth, installing the electrical and plumbing systems, and assembling the booth. The fabrication process must be carried out with precision to ensure that the booth is structurally sound and that all of the components are properly installed.

3. Testing

Once the booth is fabricated, it is tested to ensure that it is operating properly. This involves testing the powder feed system, the spray gun, the curing oven, and the control system. The booth is also tested for leaks and to ensure that it is properly grounded.

4. Installation

Once the booth has passed testing, it is installed at the customer’s facility. The installation process involves placing the booth in the desired location, connecting it to the necessary utilities, and training the customer’s staff on how to operate and maintain the booth.

5. Maintenance

Automatic powder coating booths require regular maintenance to ensure that they are operating properly. This maintenance typically includes cleaning the booth, checking the filters, and calibrating the control system. Regular maintenance will help to extend the life of the booth and prevent problems.

The cabinet is fixed on site and allows manual and automatic paint application from both sides. The frame of the cabinet is manufactured from 1.5-2 mm AISI 304. All of the parts of the paint cabinet are manufactured and disassembled, assembled with bolts and can be demounted easily when required.
