TRI-STATE PLASTICS, INC.

TRI-STATE PLASTICS, INC. specializes in the precision manufacturing of mission-critical aircraft components and auxiliary systems, primarily for defense applications. The company produces complex polymer and composite parts including air conditioning manifolds, aircraft fairings, trim panels, and fire suppression system components, often fabricated to stringent military specifications. Their technical expertise lies in thermoplastic and thermoset molding processes, dimensional precision machining, and assembly of low-volume, high-reliability aerospace hardware. They also manufacture specialized hardware and plumbing trim components used in military vehicle and aircraft interiors, demonstrating versatility across material systems and functional requirements. Their ability to deliver custom-engineered parts with tight tolerances under demanding operational environments is a key differentiator. The contractor maintains a consistent and primary relationship with the Department of Defense, supplying components for airborne systems and ground support equipment. Their work supports aviation maintenance, life extension, and sustainment programs across multiple platforms, indicating deep integration into DoD’s logistics and repair networks. While DLA Aviation appears as a specific customer, all recent awards trace back to broader Defense Department procurement channels, suggesting a focused role in the defense industrial base. The company’s core industry focus is in Other Aircraft Parts and Auxiliary Equipment Manufacturing (NAICS 336413), where it delivers non-structural, mission-enabling components that support aircraft environmental control, safety, and interior systems. Secondary capabilities include hardware and plumbing fixture manufacturing, reinforcing a niche positioning as a specialized supplier of integrated subsystems rather than airframe-level assemblies. TRI-STATE PLASTICS, INC. is a small business based in Coraopolis, Pennsylvania, operating under a 2L entity structure. The company holds no federal certifications, and its market presence is defined by technical precision and responsiveness to defense-specific requirements rather than formal program participation. Its geographic footprint is localized, but its supply chain impact extends across DoD aerospace sustainment operations.
