Non-metallic enclosures, custom built, for machine builders, OEMs

Designers of industrial machinery who use enclosures for electrical controls face challenges in enclosure weight, safety, and budget. UL listed PVC in sheet form and CAD/CAM software help with low-cost, quickly made custom enclosures, said Midwest Plastic Fabricators.


These enclosures from Midwest Plastic Fabricators range from 6x4x4 inches to 26x31x8 inches. There are no size or configuration constraints, the company said.

Machine builders and original equipment manufacturers (OEMs) can get custom enclosures using UL listed PVC in sheet form made with CAD/CAM software. Midwest Plastic Fabricators said it can achieve rapid enclosure design and delivery using a patented process to meet critical performance, cost, and dimensional requirements. In a collaborative effort, Midwest Plastic Fabricators said it designed enclosures working with the distributor and under the direction of the machine builder. Each enclosure is completed with specific panels and cutouts for conduit, fans, and A/C. Doors have key lock latches and all enclosures have robust stainless steel hardware. Flush doors add to the aesthetics of the machine design. The square design of these patented enclosures facilitates mounting onto engineered machine surfaces, as they have no draft angles. Cost is reduced by having all cut-out features incorporated during the manufacturing. This process also improves quality and speeds delivery. Features of the material – PVC and polycarbonate – include being lightweight but durable, non-corrosive, non-conductive, and not needing paint. Enclosures are manufactured to UL50, meet NEMA 4X standards, and are made in Aurora, Ohio.
