“The [machine] automatically applies a uniform finish as an alternative to hand spraying. It enables you to apply a very even coat across the entire paneling passing through it. If you try to hand-spray a large piece of material, it’s hard to lean out with your hand and get good, consistent even coverage,” product manager Brent Patterson says.

“Since you’re getting a nice even coverage with the machine, you’re applying 100 percent of the material to the part, as opposed to hand-spraying where you tend to have a decent amount of overspray lost in filters and in the air. So you get a lot better use of material.”

The machine is 50” wide to accommodate 4’ x 8’ sheets up to 2” thick.

A rubber application roller applies the finish as a part passes through on a conveyor. A doctor roll regulates the amount of finish supplied to the application roller before it is applied to a part. The machine features a variety of electronic and pneumatic controls for optimum performance.

The machine has a base price of $40,000.
