Automatic Powder Coating Booth | Spray Booth

Automatic Powder Coating Booth from Steel

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.

Stainless Steel Automatic Powder Coating Booth

A stainless steel automatic powder coating booth is a type of industrial equipment used to apply powder coatings to metal parts. Powder coating is a dry finishing process that uses finely ground particles of paint to coat a surface. The powder particles are attracted to the surface of the part by an electrostatic charge, and then they are cured with heat to form a durable, protective finish.

Stainless steel automatic powder coating booths are typically composed of the following components:

A booth enclosure: The booth enclosure is the main structure of the booth, and it is typically made of stainless steel to provide corrosion resistance and easy cleaning.
A powder feed system: The powder feed system is responsible for delivering powder from the powder hopper to the spray gun.
A spray gun: The spray gun is used to apply the powder to the surface of the part.
A curing oven: The curing oven is used to cure the powder and harden the coating.
A control system: The control system is used to control the various functions of the booth, such as the powder feed rate, the spray gun voltage, and the curing oven temperature.

The process of powder coating in an automatic booth is typically as follows:

Pre-treatment: The parts to be coated are pre-treated to remove any impurities or contaminants. This may involve cleaning, degreasing, and blasting.
Powder application: The powder is applied to the surface of the parts using a spray gun. The powder particles are attracted to the surface of the parts by an electrostatic charge.
Curing: The parts are placed in a curing oven to cure the powder. The curing process heats the powder to a temperature where it melts and flows, and then it cools to form a hard, durable coating.
Post-treatment: Once the parts have been cured, they may be post-treated to remove any excess powder or to improve the appearance of the coating.

Stainless steel automatic powder coating booths offer a number of advantages over manual powder coating methods, including:

Increased productivity: Automatic booths can coat parts much faster than manual methods.
Improved quality: Automatic booths can apply powder more evenly and consistently than manual methods.

The plastic automatic powder coating booth operates with 2 robot reciprocators on both sides, whose working height can be determined according to the height of the workpieces.

Automatic Powder Coating Booth for Conveyor Line

Automatic Powder Coating Booths can be made from galvanized sheet, stainless steel and also PVC for fast cleaning options. The air inside is calculated according to the space required inside of the booth and the circulating air inside the booth also determines the cyclone capacity

During the electrostatic powder painting process, approximately 70% of the paint sticks on the part, depending on the structure of the part. For the paint which does not get stuck on the part to not get spread in the environment, a “Powder Paint Application Booth” is required. Dimensions of the powder paint application cabinet, capacity, pressure of the sucking fan, filter count, using suitable filters, etc. is extremely important.

To create a suitable air velocity within the cabinet and overcome the resistance of the filters during the painting process, a fan with suitable quality must be selected; a sufficient number of filters must be used according to the number of powder paint guns to be used.

Because the remaining powder paint, which amounts to 30% of total paint and which does not stick to the part in the filtered type powder paint application cabinet is recycled directly, it keeps the physical specifications of the powder paint and removes the disabilities that are seen at second used powder paints such as becoming dull and denying the electrostatic.

Accumulated in the cabin floor paint is automatically directed to the cyclone swept pneumatic system. “Swept Paint Depot” and “Under Cyclone Depot” the accumulated powder coated are transferred back into the system with an automatic Powder Center. Thus, 3-4% in the filter group and very small paint particles move in, filter load decreases and life is prolonged.

Filters are not changed during color changes, filter costs are reduced. Only the booth body color change in, cyclone group, and recovery system cleaning are enough. Paint Center is very efficient equipment for paint recovery.

In the powder paint cabinet, the filters must be kept clean and their pores must be open. Cleaning of the filters is automatically performed through an electronic card located on the command panel. The opening frequency and time of the pulse valves as well as the operating and stopping time of the sub-cyclone hopper can be set on the electronic card. The pulse valves, which are set at the demanded frequency and which are opened respectively, pump compressed air into filters and pour out the powder, which was coated over the filters, to the residue hopper.

After the filters are cleaned, vibration motors operate automatically and transfer the paint accumulated in the hopper to the recycling hopper through sieving. This process goes on automatically as a set. The default settings of the electronic card were set considering its specifications and the number of powder paint pistols; however, the user is also able to make their own settings as per the terms of use change.

The Plastic Powder Paint Application Booth was designed and manufactured by EMS Powder Coating Equipment. to allow all types of powder paint to be applied.

Function definition

While the filter unit is in operation, the contaminated air enters through the inlet of the filter unit and passes through the filter cartridges. The powder/dye mixture is collected on the outside of the filters. The filtered air passes through the filters and it is returned from the output filter as clean air to the ambient.

The filter cartridges are automatically cleaned at regular intervals. Thus, the filter units can be used efficiently. During the cleaning of the filter unit, the timer sends energy to the solenoid valve and it is given compressed air from the diaphragm valve to the filters at the same time. ( to outward from the inside of the filters.)

Therefore, The powder/dye mixture which is collected outside of the filter pours under the filter unit and it is cumulated in the waste storage. With the aid of the fan on the filter unit, firstly, the dust passes through from air canals in the plastic powder coating booth. It is held in filters after passes from the cyclone separator. It is ensured the air that is given outside can keep clean. Besides, air/powder mixture concentration can keep away from explosion potential interval because of the suction fan speed

Plastic Spray booth manufacturers try to solve the cleaning problem after each color change by either inventing a new powder coating booth design or applying new antistatic materials for the booth construction. As the powder coating cost increases in accordance with the energy prices, companies need smaller stops between each color change.
