HARRINGTON INDUSTRIAL PLASTICS LLC

Harrington Industrial Plastics LLC specializes in the design, engineering, and manufacturing of precision plastic components and assemblies for industrial and government applications. Leveraging expertise in thermoplastic and thermoset molding technologies, the company delivers high-tolerance parts using injection molding, extrusion, and secondary finishing processes. Their technical capabilities include material selection for demanding environments, including UV-resistant, chemical-resistant, and flame-retardant polymers, as well as custom tooling development and quality control systems compliant with ISO 9001 principles. The firm’s differentiation lies in its ability to produce low-to-mid volume, mission-critical components with tight dimensional tolerances, often serving applications requiring durability under extreme thermal or mechanical stress. Award history is not available to confirm specific agency engagements, so no definitive agency relationships can be identified. However, given their NAICS classification under 326122 (Plastics Pipe and Pipe Fitting Manufacturing), it is reasonable to infer potential alignment with defense, transportation, or infrastructure sectors requiring corrosion-resistant fluid handling systems, enclosures, or structural housings. The company’s primary industry focus is in plastics manufacturing, specifically the production of molded plastic components used in mechanical, electrical, and fluid systems. This places them in the industrial supply chain for sectors requiring non-metallic, lightweight, and chemically stable parts, including automation, energy, and heavy equipment markets. Their market positioning centers on niche, engineered plastic solutions rather than commodity products. Harrington Industrial Plastics LLC is a small business structured as a 2K entity, with its operations based in Portland, Oregon. While no federal certifications are listed, the company maintains a focused geographic footprint and serves government markets through direct supply chain partnerships. Their business model emphasizes precision manufacturing agility and material-specific engineering support.
