All You Need To Know About Powder Coating Finishing
Power coating finishing is very important to our sheet metal fabrication parts in industry, the process can make our product appearance perfect as expected, so it is widly used for many of product design and production.
Below are mainly four power coating finishing processes
-
Importance of metal finishing
Utilization of raw metal by itself has major drawbacks. Without applying the proper finishing technique, exposed metal surfaces are likely to tarnish. This is due to their exposure to erosion by salts, ultraviolet light and rainwater, which increases chances of rusting. At Creatingway, we understand the importance of adequately finishing fabrication components as it is critical in ensuring product durability. The proper metal finishing technique does also add more value to the product’s appearance. It makes it more valuable and thus more appealing to the final user.
-
Forms of metal finishing
Over the years, we have come up with a variety of metal finishing techniques. The primary choice for most of our metal fabrication projects is liquid paint. Our professionals brush roll or spray paint solvent-based paint on most of our finished fabrications. The regular paints, whether oil or waterborne, do have their disadvantages. It takes a lengthy amount of time to apply and requires the proper conditions and expertise for its application.
We also use electroplating as a method of metal finishing. Chromium plating has a gleaming and magnificent finishing touch. However, They are expensive and time-consuming, and there are thus better alternatives to it.
-
The perfection of powder coating
Powder coating is revolutionizing the metal fabrication industry. Its advantages over liquid paint and metal pai
nt (electroplating), clearly give it an advantage over these alternatives. It is a significantly more economical and efficient technique that provides more durability to the end-product. The perfection of the powder coating process enables or metal fabricators to maximize production time while still increasing functional protective properties to the product.
-
Mechanism of Powder Coating
To properly appreciate powder coating advantages, we should mention how it works. Powder coating works in a totally dry set up, unlike liquid painting which has color pigments suspended in a liquid medium. This is its most critical differential form other finishing techniques. We avoid using liquids in powder coating since it disrupts the electrostatic spray deposition (ESD) process.
-
Curing powder-coated metal fabrications
Upon application of a uniform powder coating, we subject the object to high temperature for a specific time frame. The duration varies according to powder derivative, and it may range up to 400 degrees Fahrenheit. This process is essential since it does not dry like standard liquid paint. Once fully cured, it is immediately ready for use.
The capacity of the oven in which we place it to dry is the only limitation to the amount and size of powder-coated products. We easily coat complex shapes uniformly with this technique. This process also minimizes the chances of undercoating any of its parts. The finished product has a solid, molecular-dense outer protective coating.
What’s the advantages of powder coating finishing?
Powder finishing is an advanced metal finishing technique that has a variety of advantages over other available finishes. It makes surfaces resistant to wear, fading, scratches, chipping, corrosion or rusting. They maintain a gleaming appearing throughout their use and are virtually maintenance-free. The product does not require repainting and may require occasional washing with regular soap and water.
What’s the the benefits of power coating process?
-
Durability
Powder coating provides a hard and durable finish. We consider it among the toughest overall finish for our clients’ commercial tools and industrial surfaces. The adverse environmental conditions it withstands are extreme weather, chemical reactions, and physical abrasion. This allows free daily use and far better longevity than painting or electroplating.
-
Uniformity
Powder coating of metal fabrications provides a velvety and uniform finishing touch. This difficult to accomplish through liquid painting as it requires a unique setting. It minimizes imperfections that occasionally occur in painting such as bubbles, dust bumps and stuck insects. Furthermore, there are no run-offs, streaks or weak spots.
-
Economy
Powder coating saves on time and labor costs in comparison to painting and electroplating. This savings translates to a cheaper finished prototype.
-
Appearance
This metal finishing technique provides the most magnificent final appearance. Apart from being uniform, it allows for a variety of light reflection designs. The powder coats may be semi-gloss, high gloss or matte finishes. The textures can also be smooth, wrinkle and flaky-like.
-
Diversity
We apply powder coating to a wide variety of objects regardless of shape, size and complexity. Metal parts with sharp edges are difficult to paint, and this where powder coating comes in handy. This thus gives our professional fabricators the freedom of designing and producing wholesome products without having to paint parts separately for later assembly.
-
Reduced Processing Time
Normally, traditional paint often has to be given time to dry. Powder coated items on the other hand, go directly into the oven, hence its does not require lengthy flashy period since it does not contain any solvent. We can, therefore, get the product to you much faster.
-
More Environmentally friendly
Wet paint contains up to 70% of solvents which have to pass through afterburners due to environmental legislation. The powder in powder coating contains 0% solvent which reduces its cost and is much more environmentally friendly. The powder also ensures material loss is less than 5% and often most of the overspray is recoverable.
There are a few disadvantages to powder coating
- It is often hard to achieve thin coating layers
- Color changes are often difficult to make
- The metal fabrication part may require grinding before application of the powder coat.
- It is sometimes difficult to touch-up
