As each piece is brought in, they are inspected and logged with the customer present. After all options are discussed, color choice is made, quote is agreed on, we then move on to preparation. Paint or original powder coating is stripped and substrate is brought down to bare metal. Any rust found is treated with a neutralizer and removed with the appropriate media which includes but is not limited to media blasting for a profile that allows for better powder adhesion.
Once your piece is stripped, treated and blasted, the part, depending on the size, is either hung from a dedicated ground rod or secured to a rolling rack and goes in the oven for what is called outgassing. To outgas a piece, the oven temperature is set 50 degrees above the set cure temperature, in upwards of 450 degrees, and will remain in the oven for at least one hour, or until all impurities are forced out and cooked off. This ensures the piece is perfectly clean, inside and out and ready for powder.
After outgassing, the part is pulled and allowed to cool back down to room temperature. Powder is applied, much in the same fashion as paint, with a container of powder delivered with air. The main difference is that the powder leaves the gun with a positive charge, as high as one hundred thousand volts. With this charge, the powder is attracted to the grounded part. Once coated, the part is placed back into the oven for the curing process. Once the cure schedule is reached, the part is removed and allowed to cool. Once cooled, the part is done and ready to be put back into use.
