Powder Coating

“If you are looking for a quality product with unmatched customer service, then you have come to the right spot.”

Powder coating is an eco-friendly finishing technique that delivers a tough, attractive, and durable finish. Its application involves using a special powder spray gun, which imparts an electrostatic charge to the powder particles once they move through it. Since the products being finished are grounded, the powder gets attracted to them thanks to the electrostatic process. When the application is complete, the parts are then moved to a curing oven that sets to work by melting and crosslinking the powder coats over their surface. The end result is a tough, scratch-resistant, and attractive finish. Powder coating may be applied to a wide variety of substrates including metals, plastics, wood, and more. Let us now take a closer look at the key powder coating techniques you could choose from.

Electrostatic deposition In this powder coating process, you will need a powder feeder, a powder coating spray booth, and last but not least, an electrostatic spray gun. The paint booth, in particular, happens to be the workspace that acts as an air filtration and overspray containment area. In the electrostatic deposition method, the gun is utilized to impart an electrostatic charge to the fluidized powder before it gets applied to the substrate. One of the main benefits of this powder coating process is the overspray may be collected using special recovery systems that will be covered here later on. This definitely means that the overspray recovered can be reused in future operations.
Fluidized bed powder coating  The fluidized bed powder coating process commences with preheating the products before they can be finished. Once this has been done, they are then dipped into the powder material that is stored for use in a specialized fluidized bed. In some situations, electrically-charged powders may be applied to the substrate prior to dipping it in the fluidized bed. 
Powder coating spray gun As it was earlier noted, powder coating application is achieved with a specialized powder spray gun. For the application to be successful, the powder material needs to be electrostatically charged. So, the only means of doing so is by utilizing a spray gun purposefully built for this specific finishing process. Compressed air forces powder material to flow through the gun from either a hopper feeder or directly from the container where the powder material has been deposited. Once the powder passes out of the gun, it is ejected in a tightly-formed cloud that is electrostatically charged. The moment this happens, the cloud of powder is attracted to the grounded substrate and sticks to its surface.

Powder coating spray booth 

Our powder coating spray booth is partly designed to contain overspray and other contaminants and keep the finishing area clean. It also offers a well-illuminated space where powder coating may be performed with enhanced precision. This sort of paint booth comes complete with either a single or multiple exhaust fans and intake and exhaust filters that set to work by capturing overspray and other contaminants. This combination of exhaust fans and filters makes sure the airflow created in the unit keeps overspray within the workspace and allows the operators to see what they are doing. Should your facility have welding or blasting areas, a powder coating spray booth may feature filtered doors that will help keep airborne contaminants away from the substrate’s powder-coated finish.

You will always be spoilt for choices when it comes to picking the right ZPar International paint booth configuration for your unit. Some of the key factors which will guide your selection include the size of the products you will be finishing, the available floor space in your shop, and lastly your unique workflow needs and preferences. A powder coating spray booth may come with doors at each of its ends or may be open-faced. Alternatively, it can be designed and engineered to be a tunnel-styled enclosure with filtration built into the floor and walls. In the event your facility lacks the space to install a booth, there are powder spray walls made available in the market. These products will enable you to achieve the same airflow and filtration as full-sized units.
Should you desire to reuse your powder coating material, you will have to install a reclamation system. Typically, such systems work by using pleated cartridge filters that recover overspray for reuse. Most of the time, this is a very cost-effective solution over time. Should you make use of a single color and powder type for your powder coating operations, these filters work by trapping spent powder that is then relayed to a recovery bin. On the flip side, there are more advanced systems where the powder material may be reconditioned and blended with virgin powder and ultimately fed into the powder spray gun’s supply hopper. In the case you utilize multiple colors, there are detachable filter modules you could install to reclaim spent powder material.
Powder coating curing ovens  The final step in the powder coating method is curing the substrate. Powder curing ovens tend to operate at temperatures of between 325o F- 450o F. In such an oven, the powder-coated products are exposed to air that is precisely heated for a given duration of time, normally between 10 minutes to an hour. Some curing ovens integrate infrared emitters. However, such advanced systems are costly to purchase and also expensive to maintain over time. Oftentimes, powder coating curing ovens tend to incorporate electric heating elements, gas-powered or LP-fueled heating systems.

Powder coating clean rooms 

Should you have to enforce strict finish requirements, you will certainly need a cleanroom that is otherwise known as an environment room. Essentially, this is a climate-controlled enclosure which is constructed surrounding the powder application area. Its main function is to do away with airborne contaminants. While, at the same time, regulating both temperature and humidity of the booth during the powder coating process. In turn, this helps in preventing any kind of contamination, clumping, or finish consistency problems. A cleanroom is usually a very effective solution if the substrates you want to be finished need exact specifications for adhesion or even salt spray tolerance.

Booth Construction

The booth walls and roof are made of 18 gauge or thicker steel that has been G90 galvanized. The booth utilizes a single panel design. The walls and roof are connected via a track system. The booth is bolted together and the exhaust system is integrated into one or more of the booth’s walls. Threaded inserts in key parts help simplify assembly. No field welding is required.

Lighting

The spray enclosure includes roof-mounted light fixtures designed to accommodate four standard 48” T-8 bulbs. These fixtures are mounted on special panels that include factory-provided reinforcement. The light fixtures are mounted in the field over sheets of ¼” tempered safety glass that are sealed in place. The light fixtures are accessible only from the booth’s exterior.

Exhaust Unit

The exhaust unit is included in the exterior dimensions for the booth. The booth uses either one or two floor mounted exhaust units. The exhaust unit is constructed of primarily 16 gauge and 18 gauge G90 galvanized steel. The exhaust system utilizes a belt-driven tube axial fan and includes a two stage or three-stage filter system to draw air through the booth enclosure which will either exhaust the air to the outside or return it to the shop atmosphere. The exhaust unit uses an ASHRAE/NESHAP type system consisting of a primary blanket filter, a set of polyester cube filters and a set of HEPA type final filters. The exhaust unit is designed to draw air from the lower 1/3 of the wall of the booth, resulting in semi-downdraft airflow. The booth ships with tackified 1” blanket type pre-filter media, 24”x 24” x 12” duo-ply polyester cube filters, and optional 24”x 30” x 6” true MERV 17 HEPA filters with integrated galvanized metal housings.

Controls

The booth is operated via a simple control panel in a NEMA enclosure. The control panel allows the operator to stop and start the exhaust fan and turn the lights on and off. The control panel includes over-current protection. Upgraded models include adjustable airflow via a face-mounted VFD control knob.

Outsourced Components

Exhaust duct is not required when HEPA filters are used. Light bulbs, parts for electrical service connection to the control panel, and field wiring components are provided by other companies and are not considered part of the deliverable.
