Processes

Fluidized Bed

The fluidized bed method consists of a tank of powder this is aerated from below. Aeration causes the powder particles to become suspended into a fluidlike bath of turbulent particles. When a preheated metal part is immersed into the tank, the powder particles melt and adhere to the surface. The heat activates the particles, causing them to fuse into a continuous coating that bonds to the part. This method is best suited as a functional coating to provide abrasion, corrosion, and chemical resistance. Typical thickness for this method is .007”-.015” thickness, but heavier thickness can be achieved.

Electrostatic

Electrostatic spraying is the most popular method of applying powder coating. The plastic particles are charged with electrical current as they are shot from a spray gun. The part to be coated is connected to or suspended from an electrically grounded contact so that it attracts the negatively charged particles, forming a continuous coating. Spraying a cold part can get a thinner coat, while pre-heating the part will allow for thicker build up. Typically, electrostatically spraying will get you .001”-.004” thickness, but multiple coats can be applied to achieve a heavier coating.

Mini Coat

Our state of the art mini coat process allows us to completely encapsulate small metal parts in large quantities with great efficiency. Generally limited to parts that weigh less than 3 ounces and are no larger than 3 inches in length, we can achieve a thickness range between .003” and .009” (heavier coating is possible). This process lends itself well particularly to the automotive industry. We’ve coated a variety of parts including clips, springs, and hooks in this super-efficient method.
