When you make a product made out of metal, you want to make sure that it's protected when you are done with it. There are various ways that you can do that. One of the ways that you can do that is to powder coat the metal.
Powder coating can be made out of many things, but it generally some kind of thermoplastic. It's adhered to the finished product electrostatically. That means a weak electrical charge is run through metal piece and the coating is attracted to it, similar to static electricity and hair. Once the coating has adhered to the metal, it is then baked on by going through huge kilns or ovens. Once it cools, the piece is finished. There are a lot of benefits to using powder coating for your metal piece.
One big benefit is that it is much easier to powder coat something than it is to paint it. With a powder coat, everything is done in one fell swoop. You don't have to worry about base coats, color coats, and top coats. Just send the material through the powder coat and then it's done. If you want to have something colored, then there are powdered dyes and such that can be added to the coating and then you get the color you want.
Another reason that you might want to go with powder coating on your product is that it can be more durable than paint. It's going to take a whole lot to get that powder coating off the material than it's going to be to scratch off some paint. That's why you can find powder coating on things that are going to take a lot of abuse, like tool boxes and in the backs of some work trucks.
Powder coating also helps to give better corrosion protection than paint does. Paint can get scratched, which can expose the metal underneath to water, which can cause rust. Not only that, but the water can get further under the paint, and which will cause the paint to peel. But since powder coating is so durable, that isn't as much of a problem, meaning that powder coating is good for a product that is going to be left outside.
If you are going to produce a metal product, you want to make sure that you are getting the right finish for it.
