ANODIZING – Companies chose the anodizing process for its versatility, environmental advantages and ability to produce finishes that are both distinctive and functional. We engineer and build architectural anodizing systems for continuous run and batch processing. Systems are widely used for aluminum-framed entrances, windows, exterior decorative elements, skylights, and lighting. Each process line is custom-engineered to the specific needs and production environment of the customer, but most lines begin with an alkaline clean, and acid or alkaline etch, deoxidizing and desmutting, followed by type II anodize and 2-step electrolytic color.

ELECTROCOATING – We have extensive experience in all major electrocoating techniques, such as continuous conveyorized systems, indexing systems, and bulk coating systems, where parts can be randomly packed.

LIQUID COATING – We have repeatedly advanced and refined liquid coating technology to enhance coating performance, respond to environmental issues, and meet the needs of our customers for high uptime performance and low life cycle costs. Today, our systems are used alone or in combination with e-coat and powder to meet stringent quality, cost, operating, and emission requirements.
