Composites USA enclosures are designed and manufactured for rugged industrial use where part weight and contact with corrosive chemicals or sea water might be a concern. Although designed for industrial environments, these enclosures also receive the same fit, finish and attention to detail that our electronic housings for radar and instruments have. Shown on this page are several styles of enclosures, including the three sided instrument enclosure above and the process tank with integral equipment enclosure below. This part was used to temporarily enclose gas chromatographs in an oil refinery. Other enclosures might typically protect remote pump stations from unwanted tampering, or protect personnel from rotating machinery parts. Each enclosure design is rigorously checked by our composite structural engineers for wind, snow and operating loads The laminate begins with a resin rich corrosion barrier, reinforced with a fiberglass or synthetic veil and several layers of random chopped strand mat. The structural portion of the laminate is constructed with random chopped strand mat and continuous strand glass, biaxial, unidirectional or otherwise oriented to meet the design considerations. These layers are gradually built up to the final required thickness, sometimes incorporating structural cores on large flat panels to increase stiffness and strength. The top exterior layer is usually applied with a resin pigmented to the customer's preferred color choice, for long-term color stability, which will not chip or flake off. In this way, the color is molded in, part thickness and reinforcement uniformity is carefully controlled, and problems with typical trouble spots, such as voids and inside corners, are avoided. Non skid grit surfaces are available for increased personnel safety. With a Composites USA enclosure, you get a cover designed to the latest codes, and quality audited to MIL-I-45208 and Factory Mutual standards. All resins used are corrosion resistant polyester or vinyl ester, with flame retardant options available.
