Powder Coating

Being an OEM ourselves, we realize the importance of prompt service and accurate information. Additionally, we understand the priority of a consistent, attractive finish and meeting customer requirements. These basic tenets precipitated our decision in 1991 to go ahead with expansion plans to add a modern powder coating operation. Thus, today we are able to directly maintain and control the quality of our product from start to finish.

Signa’s state of the art powder technology produces a quality finish that exceeds that of liquid coatings by offering superior surface properties and better process economics.

Powder coating offers "one or a combination of desirable characteristics including; durability, resilience, high gloss, electrical insulation, toughness; and resistance to wear, corrosion, impact, chemical action and weather." (Nordson Corporation)

Signa’s Unique Powder Coating Features
Our 660’ automated overhead conveyor relays parts through our five stage, pressure spray washer system pretreating parts with alkaline cleanser and iron phosphate.

Next they travel through the dry-off oven before entering the climate controlled powder room. Here the parts are sent through one of the largest Nordson coating booths in Northeast Ohio with a 90" (H) x 28" (W) opening. One of the benefits of our Nordson system is the cyclone reclaiming system, which offers up to 95% efficiency.

As parts enter the powder booth fourteen (14) automatic spray guns apply a full coverage. However, before exiting the booth, they must pass through inspection and touch up done by our two (2) manual assist gun operators.

Parts then exit the powder room and travel into a convection cure oven where parts are cured per the technical data sheets of the powder being applied.

Finally, parts pass through rigid quality inspection (including visual inspection, mil readings, pencil hardness, and MEK rubs) and are packaged per your specifications.
