Aside from steel, most metals will eventually rust without any protective coating. The coating finish you choose can have a lasting impact on part durability, longevity, aesthetics and quality.
Powder coating is a dry finish technique that provides many unique benefits. During the process, dry powder is applied to metal parts through an electrostatic spray gun. The part is then cured with heat to adhere the coating to the metal surface. When compared to other finishing methods, powder coating creates greater part durability, higher quality, process efficiency and sustainability.
Here’s a closer look at why your sheet metal fabrication project should include a powder coating finish.
1. Increases Part Durability
Powder coating produces a thick, protective layer that provides long-lasting part durability. Powder coating is able to withstand harsh weather environments and physical impact, providing excellent resistance to:
A significant advantage of powder coating is that once it is applied, additional layers can be added to increase thickness and provide even greater protection. The thicker the coating, the greater protection for your metal part.
2. Extremely Efficient
The powder coating process is much quicker than painting or other finishing methods. During the coating process, powder is applied all at once, meaning there is no wait time in between coats for your sheet metal to dry. Quicker dry times reduce overall lead times, making powder coating the more time and cost-effective process.
At Blackstone Advanced Technologies, our top-of-the-line robotic equipment automates the powder coating process. This allows the process to be easily repeatable for future sheet metal fabrication projects. Learn more about our powder coating technology here.
3. Higher Quality Finish
Powder coating produces an overall higher quality part than other finishing techniques. When it comes to painting, you may risk uneven coating, running or dripping. Powder coating eliminates those risks, providing a smooth, evenly distributed surface finish every time.
After a metal part is powder coated, you can expect minimal maintenance throughout its lifespan. Depending on the surface preparation and powder you choose, your powder coating should last anywhere between 7-15 years.
4. Environmentally Friendly
Wet finishes often release harmful air pollutants, known as volatile organic compounds. These chemicals are known to be toxic and can lead to lasting adverse health effects.
The powder used in powder coating is free of any harmful chemicals or pollutants. Additionally, wet finishes are often oversprayed, creating extra waste and unnecessary pollution. The powder coating process avoids waste by allowing excess powder to be vacuumed back up, which minimizes the impact on the environment.
