TSI PLASTICS, INC.

TSI PLASTICS, INC. specializes in the precision manufacturing of mission-critical polymer and composite components for defense aerospace and ordnance systems. Their core capabilities include the design and production of specialized aircraft access covers, air mixer nozzles, and shipping plugs—parts requiring tight tolerances, environmental resilience, and compliance with military specifications. The company demonstrates deep expertise in thermoplastic and thermoset molding techniques suited for high-stress, low-weight applications in aircraft and ordnance environments. Their technical proficiency lies in producing non-metallic, non-conductive, and corrosion-resistant components that meet stringent DoD performance and safety standards, often replacing metal parts to reduce weight and improve system durability. The contractor maintains a consistent and exclusive relationship with the Department of Defense, delivering precision-molded parts for aircraft systems and ordnance logistics. Their work supports maintenance, safety, and operational readiness across naval, air, and ground platforms, with recurring contracts for identical components indicating trusted, long-term supplier status within defense supply chains. Their primary industry focus is in aerospace component manufacturing and ordnance accessories, specifically under NAICS 336413 (other aircraft parts and auxiliary equipment) and 332994 (small arms and ordnance accessories). These classifications reflect a niche positioning as a specialized supplier of non-metallic, mission-specific parts that enable system integration, handling, and environmental protection in defense hardware. They serve a highly regulated vertical where material selection, dimensional accuracy, and batch consistency are critical to mission success. TSI PLASTICS, INC. is a small, privately held manufacturer based in Anoka, Minnesota, with no federal certifications on record. Despite the absence of formal small business or socioeconomic designations, their sustained contract activity with the DoE suggests a reputation for reliable, high-quality production in a technically demanding market. Their geographic footprint is localized but operationally significant within the defense industrial base.
