HARRINGTON INDUSTRIAL PLASTICS LLC

Harrington Industrial Plastics LLC specializes in the design, engineering, and manufacturing of precision plastic components and assemblies using advanced thermoplastic and thermoset molding technologies. Their core capabilities include injection molding, extrusion, and secondary fabrication processes tailored to meet stringent dimensional tolerances and material specifications required in defense, aerospace, and industrial applications. The company leverages expertise in high-performance polymers such as PEEK, Nylon, ABS, and polycarbonate, with an emphasis on producing low-to-medium volume, mission-critical parts for environments demanding durability, chemical resistance, and thermal stability. Their technical differentiation lies in in-house tooling development, process validation, and quality control systems aligned with industry best practices for repeatable, high-integrity production. Award history is not available to confirm specific agency engagements, so no definitive patterns of government client relationships can be inferred. Similarly, without recent contract data, it is not possible to identify primary federal or state agency partnerships or the nature of work performed for them. The company’s primary NAICS code, 326122, corresponds to plastic pipe, tube, and profile manufacturing, which in practice indicates a focus on producing custom extruded and molded plastic components rather than commodity products. This positions them within niche industrial supply chains requiring engineered polymers for mechanical, electrical, or structural applications, particularly where standard off-the-shelf parts are insufficient. Harrington Industrial Plastics LLC is a small business organized as a 2K entity, with its operations based in Riverside, California. The firm holds no active government certifications such as 8(a), HUBZone, or SDVOSB. Its geographic footprint is localized, and its government market presence is currently unverified due to lack of publicly available contract performance data.
