In recent times, powder coating services have become quite important among fabricators for those requiring a highly durable, quality finish on various metal surfaces. From industrial products to consumer products, powder coating provides durability, attractiveness, and eco-friendliness. However, what does the process entail in powder coating? The process guide will take you through every step of the way involved with powder coating, from application to completion.
What is Powder Coating?
Powder coating is a dry finishing process that uses finely ground particles of pigment and resin for coating, applied by electrostatic guns, and then cured under heat to a smooth, durable finish. Unlike liquid paint, which is delivered to the substrate as a liquid followed by evaporation of the solvents, powder coating powder is in finely ground form upon application.
The powder melts and flows into a uniform powder coat finish when heated in the oven after application. The process has wide applicability in several industries, but most especially in the industrial powder coating, where it is required to be strong and not easily damaged or worn out.
The Powder Coating Process
- Surface treatment: This is a process that takes place just before the powder coating application to the metal surface. The metal needs to be appropriately pre-treated for an even adhesion of the powder coat and a smooth, faultless finish. This often consists of surface treatment such as sandblasting, degreasing, or other cleaning methods.
- Application of Powder Coating: The prime method for applying powder coating is through an electrostatic spray gun. This spray gun imparts a positive charge to the powder coating powder, attracting it onto the grounded metal part. The whole surface will be properly coated, even complex shapes.
- Curing: Once the powder coating has been deposited, the item undergoes a heat treatment in a curing oven; it melts the powder and causes it to flow together as a continuous layer. The time of curing, as indeed the temperature, depends on the type of powder coating being used, along with the thickness of the layer.
- Curing: This is the final stage wherein the product is cooled. It will reveal a resilient, robust powder coat finish. Other processes may be involved, such as inspection, polishing, or an additional coat to conform to a certain requirement.
Benefits of Powder Coating Services
Among the major reasons why powder coating services are in such high demand is because of the quality finish they offer. The process gives a coating tougher than that of traditional paints, hence offering more resistance to chipping, scratches, and fading. Another environmental merit of powder coating cost is that it does not emit harmful solvents into the atmosphere.
The cost of powder coating depends on the size and complexity of the item treated. However, because the process generates minimal waste—the unused powder can often be used again—the powder coating cost can be very competitive as compared with traditional methods of painting.
Applications of Powder Coating
Powder coating finds immense applications in industry for automotive, construction, and consumer goods. From car rims to metal furniture, powder metal coating provides a great finish for products that come in contact with harsh environmental conditions. The resistance against extreme temperatures, moisture, and chemicals makes powder coating perfectly suitable for both decorative and functional purposes.
