Because the parts to be coated are rectified, the dust is attracted to the part via the electrostatic process. Once the powder has been applied, the parts are cured in an oven, which melts and reticulates the powder on the surface of the part and creates a firm, scratch resistant and beautiful finish. It is most often used in instances to create a hard finish that is stronger than just conventional paint. Powder coating is mainly used for metal coating, such as household appliances, aluminum extrusions, drum hardware, cars and bicycle frames. The powder coating spray gun gives the powder a positive electric charge, which is then sprayed onto the rectified object by mechanical spraying or compressed air and then accelerated into the workpiece by powerful electrostatic charge. Once sprayed through a gun gun and applied to the surface of the part, an oven is used to melt the dust and make a film. Powder coating is an excellent choice for applications where durability and toughness are important, because the end product has a more durable surface than traditional liquid coatings. Advanced technology and innovations in dust coating equipment and curing ovens have led more companies to invest in domestic production equipment.
While the powder coating process may have lower costs over time, it may be more cost effective for specific coating applications to use liquid coatings. For manufacturers and suppliers of finishing services starting, the initial investment in powder coating equipment is also usually greater than with liquid coating, as the process requires a spray gun, a specialized spray booth and a curing furnace. Powder coating uses technology similar to liquid electrostatic paint, the main difference being that the powder coating uses a dry resin material that does not require a solvent medium used to keep the resin and binders in suspension.
If your retail environment contains welding or blasting areas, filtered doors in the spray booth can keep airborne contaminants out of their powder coating. Powder coating is a surface finishing option that uses a relatively thin film to provide excellent corrosion protection and chemical resistance in a very cosmetic way. While parts are often designed with specific colors, clarity and textures, powder coating types are often overlooked, but are a critical part of any powder coating.
When using powder coating, the guns always ensure that it is well ground and has a dust cover for the nose and mouth. Consider buying a powder coating gun that is portable and easy to clean, especially when going from one color to another. By adjusting the air outlet, you can flow quickly or slowly from the dust layer, depending on the type of spray task. The Hyper Smooth 02 LED dust coating gun is attached with power and ground cables, a flat nozzle, standard 1 “mouth, standard 1 lb and 2 lb hoppers, a power supply and a multiple mouthpiece with wide mouth.
Like electrostatic paint guns and systems, dust is negatively charged when it enters the gun and parts are rectified to attract dust. In addition, there are no special powder coating licensing rules as they exist for liquid paint applications. Whether you’re new to powder coatings or an experienced professional, you probably know that powder coating is a fantastic dyeing method that creates a sturdy, durable and beautiful finish. No matter if you use a single gun and a small oven or a fully automated big line, the process is basically the same.
