The powder is applied with an electrostatic spray gun to a part that is a grounded.

Before the powder is sent to the gun it is fluidized which means “to separate the individual grains of powder and to improve the electrostatic charge that can be applied to the powder and by doing this, the powder will flow easily to the gun.

Because the powder particles are electro statically charged, the powder wraps around to the back of the part. By collecting the powder and filtering it, the efficiency of the process can be increased to almost 100% material usage. To obtain the final coating the powder coated items are placed in an oven and heated to temperatures that range from 320 to 410 degrees F. The particular powder used will determine the temperature needed.

There are a total of 4 stages until the powder coating process is completely done.

1st stage – Melt

2nd stage- Flow

3rd stage- Gel

4th stage- Cure


The choice of colors and finishes are limitless as long as the powder coating manufacturers offer it. Powder coating produces a high specification coating which is tough, hard, and abrasion resistant.
