Powder coating your parts is not a simple or haphazard process. It involves a very methodical approach that focuses on maintaining high quality and protecting the environment. Take a look at a typical day in the life of your powder coated part.
Step 1: Cleaning
Each part is subjected to a thorough cleaning process that is designed to strip it of any dirt, debris or oils that could make it difficult to obtain the paint finish desired. While the actual cleaning solution used depends heavily on the substrate material, most cleaning begins with an alkaline solution. Tanks of prepared solution await your part — regardless of its size.
Step 2: Rinsing
Rinsing is a crucial step that must be utilized so that all traces of both the cleaning solution and any debris that might still be clinging to your part are effectively removed. Depending on the cleaning process as well as the substrate of the part, this rinsing could involve immersion tanks, spray rinsing or reactive rinsing for certain chemical-based operations.
Step 3: Phosphating
Though this step is optional for some parts, it is often utilized for both steel and aluminum. Coating these substrates with phosphates serves two primary purposes: the powder coating adheres more readily and it serves as a barrier to corrosion in the event that the coating is scratched.
Step 4: Drying
Drying methods could vary depending on its goal — rust prevention, preparation for the next step or preventing water spots. Some examples of methods that could be used are a final rinse using hot deionized water, air drying and using high-pressure blowers.
Step 5: Powder Coating
This is the actual step where your part is expertly coated with the highest quality powder coat to meet your exacting standards.
Step 6: Curing
Curing the powder coat paint is the final step that your part undergoes. It is designed to provide your part with a finished look that is free of imperfections from particles in the environment. Often infra-red heating is the preferred method of curing as it delivers the bulk of the heat energy exactly where it is desired.
