Powder Process
This is a general overview of how powder is applied.
Basic Powder Coating Process:
1. Inspected: All parts are inspected for blemishes and non conformity.
2. Masking: Threaded holes, studs, and other area that are not to be powder coated are Masked per customers specification.
3. Racking: Parts are hung on a metal conductive rack in the most efficient way possible.
4. Pre-treated: This varies on sub-state metal and final application of part. (Our friendly staff can recommend the proper pre-treatment for your application.) Some pre-treatment methods are, media blast, detergent wash and iron phosphate etch, non-chrome sealer and dry in place sealers.
5. Powder Application: The powder, which is finely ground pigment and resin, is applied via an electrostatic process in which the powder is charged with either a positive or negative charge and the metal parts are charged the opposite polarity. The powder is applied to the powder manufactures specifications.
6. Curing: The powder is then cured in oven to the powder manufacturer’s specification.
7. Inspection: Once the part is out of the oven and cooled to less than 100 degrees, the parts are inspected and un Masked if applicable.
8. Packaging: Parts that pass inspection are packaged to customer’s specifications.
