The most common way of preventing a metallic object from corrosion is by applying paint on the object’s surface. However, there are disadvantages to applying paint on the object’s surface. The drawback of painting is that the coating can be uneven. Moreover, it drips more, and wiping it from the floor can be tedious.
Of late, powder coating has increased as the method offers an even surface coat that gives the object’s surface a fantastic finished look. Many companies designate powder coatings because of;
- Allowing for maximized production of high-quality
- Improved efficiencies
- Simplified environmental compliance and
- Durable finish
Powder coatings come in many textures and colors and thus ideal for both decorative and functional finishes. Powder coating ovens have emerged as an ideal alternative to conventional painting methods with many benefits for producing excellent functional metal parts with ideal surface properties and rust-resistant properties.
Main benefits of powder coating ovens
Solvent-Free Surface Protection; these ovens project a stream of charged particles onto a substrate before curing at low temperatures of less than 200 °C. The powder stream is solvent-free and dry, ensuring it complies with Environmental Protection Agency regulations on Volatile Organic Compounds emission.
Thicker Uniform Coatings; Powder coating ovens use electrostatic methods for maximum bonding between the metallic substrate and powder particles. In spray-painting, the bottom paint layer attaches to the substrate causing successive layers to sag or run. This challenge is eliminated if you use powder coating ovens.
Improved Optical Regularity; Paint often displays optical variations, which depend on the application direction. Powder coating ovens impart little or no visual differences between horizontal and vertical planes of application- ensuring the high optical uniformity for commercial coatings with fantastic color and gloss retention.
Specialty Capabilities; Liquid coating is limited in terms of its functionality and giving rust-resistant skin. Powder coating can be designed for a wide range of additional properties. Depending on the composition of the powders applied, the electrostatic coating can enhance the substrate’s chemical and mechanical capabilities while offering good electrical insulation properties.
Higher Throughput; A powder coating oven requires significantly less curing time than liquid paints. Ovens are needed for curing powder coatings. A powder coating oven does not need solvents; this ensures that curing is compliant with Environmental Protection Agency regulations regarding the emission of Volatile Organic Compounds.
How do Powder Coating Ovens Work?
When the surface is coated, a powder coating oven makes the powder stick to the metal firmly, which makes it highly durable. The powder becomes a smooth substance that seems like it has been painted on. Powder coating ovens heat the coating at a predetermined temperature, making sure that the powder coating goals are achieved. The coating oven should contain heating elements that can direct heat to the whole coated body in a process referred to as convection heating.
The most vital feature of powder coating ovens is their volumetric capacity. These ovens are often used in automotive industries to coat critical parts to prevent them from warping or degrading during their use. Thus, a powder coating oven requires the volumetric capacity to handle larger structures and components while having appropriate levels of control that guarantee similar conditions in the curing chamber.
