the powder coating process
Powder coating is a “green” friendly painting process introduced in the late 1940’s where the paint is actually a dry powdery material. The powder is sprayed at and clings to the part, then goes into an oven, where it is cured. During the curing process, the powder turns into a liquid and flows for a uniform coating. When the part comes out of the oven, it needs only to cool and is then ready to be put to use, or continue on through the dye sublimation line for further processing.
Powder coating stands up better to common dings and damages than paint.
It can bend and flex with the materials it's bound to.
It produces a coating twice as thick as paint.
Powder Coating actually costs the same, if not less, than painting
Due to its flexibility, you can coat more of the material with less powder than paint, meaning less work and more savings.
Powder coating produces no solvents, unlike paint.
Extranneous powder can be be retreived and reused
Powder coatings meet all EPA requirements for air and water pollution control.
We powder coat for our clients in two different ways, depending on the size of the product needing powder coating. For smaller and oddly shaped materials, we use the in-line process. For our large materials such as trailers, we use the batch process. Below is an explanation of how these processes work.
The In-Line Process
Parts are hung on fixtures in our overhead conveyor, where they proceed through a 5 stage cleaning process and drying cycle.
Parts go into the spray booth for the application of powder.
Parts are put into a bake oven, and then a cooling oven.
Parts are inspected, unloaded, and then packaged and shipped.
The Batch Process
Parts are cleaned, phosphate is added for metal parts, and the parts are hung to dry on fixtures.
Parts are then grounded and sprayed with powder and rolled into an oven to cure
The parts are cooled and ready to inspect, package and ship.
