About PDI Duct
Based in North Chelmsford, Massachusetts, Plastic Design Industries (operating as PDI Duct) has been fabricating PVC and CPVC duct systems since 1976. The company began as Plastic Design Inc. and has spent nearly five decades specializing in thermoplastic fabrication for corrosive environments. The company operates a 30,000-square-foot facility with a 21,000-square-foot manufacturing floor equipped for nitrogen-purged hot-gas welding, CNC machining, CO2 laser cutting, pipe fusion, and deionized-water testing. It produces standard fittings such as elbows, reducers, saddles, dampers, and blast gates in diameters from 6 to 24 inches, as well as custom-fabricated duct runs, manifolds, and transitions. Production spans one-off prototypes through full production runs. PDI Duct serves engineers, contractors, and facility teams in chemical processing, wastewater treatment, semiconductor manufacturing, pharmaceutical production, testing laboratories, and general industrial ventilation and manufacturing plants. Its systems handle corrosive air handling, fume exhaust, and process applications where metal ductwork would fail. The company emphasizes its dual-material expertise in PVC and CPVC, in-house design-to-delivery control, and certifications including ISO 9001:2015 and IPC-A-620 welding standards to ensure leak-resistant, durable installations.
