HARRINGTON INDUSTRIAL PLASTICS LLC

Harrington Industrial Plastics LLC specializes in the design, fabrication, and precision molding of engineered thermoplastic and thermoset components for industrial and government applications. Leveraging advanced injection molding, extrusion, and secondary machining capabilities, the company produces high-tolerance plastic parts used in mechanical, electrical, and environmental systems where durability, chemical resistance, and dimensional stability are critical. Their technical expertise includes material selection for extreme conditions, tooling design for complex geometries, and compliance with military and industrial specification standards such as MIL-SPEC and ASTM. Differentiators include in-house prototyping, rapid tooling turnaround, and quality control processes aligned with ISO 9001 principles, though formal government certifications are not currently held. Award history does not provide sufficient detail to identify specific federal agencies or recurring contract patterns, so no definitive agency relationships can be confirmed. The absence of recent award data limits the ability to characterize mission-specific work or programmatic engagement with government entities. The contractor’s primary NAICS code, 326122, corresponds to plastic pipe, pipe fitting, and other plastic product manufacturing. In practice, this translates to the production of custom plastic housings, enclosures, gaskets, seals, and structural components used in defense, transportation, and industrial automation sectors. Market positioning centers on niche, low-volume, high-complexity plastic component supply for specialized mechanical systems where off-the-shelf solutions are inadequate. Harrington Industrial Plastics LLC is a small business structured as a 2K entity, headquartered in Elriddle, Maryland. The company operates as a specialized manufacturer without active federal certifications such as 8(a), HUBZone, or WOSB. Its geographic presence is localized, with operations focused on serving regional industrial and government supply chains through direct contract manufacturing relationships.
