HARRINGTON INDUSTRIAL PLASTICS LLC

Harrington Industrial Plastics LLC specializes in the design, engineering, and manufacturing of precision-engineered plastic components and assemblies for mission-critical government applications. Leveraging expertise in thermoplastic and thermoset molding technologies, the company delivers high-tolerance parts using injection molding, extrusion, and secondary finishing processes tailored to stringent environmental and mechanical performance requirements. Their technical capabilities include material selection for UV resistance, chemical compatibility, and thermal stability, with an emphasis on meeting MIL-SPEC and ASTM standards for durability in harsh operational environments. Key differentiators include in-house tooling development, tight process control for repeatability, and capability to produce low-to-medium volume batches with rapid turnaround, serving applications where reliability and material consistency are non-negotiable. Award history is not available to confirm specific agency relationships, but the contractor’s core competencies align with needs across defense, aerospace, and federal logistics sectors that require durable, non-metallic components for instrumentation housings, sensor enclosures, and mechanical subsystems. Their work supports systems requiring EMI shielding, flame retardancy, or low outgassing properties, often integrated into equipment deployed in field or aerospace conditions. The primary NAICS code 326122 reflects a focus on plastic product manufacturing, specifically in the production of plastic parts for industrial, military, and institutional use. This positions the company within the broader supply chain for engineered polymers used in equipment where weight reduction, corrosion resistance, and electrical insulation are critical advantages over metal alternatives. Harrington Industrial Plastics LLC is a small business entity structured as a 2K concern, with its operational base in Denver, Colorado. The company holds no federal certifications, and its market presence is defined by direct contract execution rather than programmatic participation in set-aside initiatives. Geographic proximity to key defense and aerospace corridors enhances its ability to support regional government contractors and federal facilities requiring localized, responsive manufacturing support.
