Powder Coating Basics

Powder coating is the science of applying a light protective finish to many different products through the use of electrostatic charge. This allows the powder to adhere to the part until it is baked into a smooth, durable coating.

Choosing Powder Coating

Items that are powder coated simply last longer. Products with a coated finish are far more resistant to scratching, chipping, fading and wear that comes as a result of years of use. The choices are limitless, and the pigments will stay bright and vibrant longer. You can also choose high or low gloss, metallic or even a clear finish. Various textures, like wrinkled, matted, and rough are also available. Powder coating will never run or drip, so the coating is much easier and faster to apply as opposed to traditional paint.

Powder Coating is tough, looks great and lasts a long, long time. It is a superior finish that can be found on hundreds of products you come in contact with every day. It makes products durable, attractive and scratch resistant.

Different Coating Types

There are two main coating types. Batch Coating means parts are done in a batch, not on a conveyor line. Each part receives individual treatment. We can pay more attention to corners, inside surfaces, hard-to-get areas and intricate designs. We can coat one part or 10,000 parts. We can coat one part red and the next green and so on. This allows us to coat a needle on the first run and complete a wrought iron Volkswagen on the next run.

Line Coating means that the parts are put on a conveyor, then put through a tunnel that accommodates only certain size parts. This tunnel contains automated guns, which coat the parts as travel along the conveyor. These guns don't do intricate patterns; they are set to coat small parts on two sides without corners or inner sides.

With Line Coating, you can do 10,000 parts but not one. A colour change, while possible, could take 3 to 4 hours to do change to the next colour. Coating intricate parts is not possible.

Batch systems are more flexible; They allow rapid changes in your cycles with several different colours and many sizes. We do batch coating for the versatility.
