TRI-MACK PLASTICS MANUFACTURING CORP

TRI-MACK PLASTICS MANUFACTURING CORP specializes in the precision manufacturing of engineered plastic and composite components for defense applications, with a primary focus on bushings, sleeves, and flat washers used in high-stress mechanical systems. Their technical expertise lies in producing dimensionally critical, wear-resistant plastic parts that replace or complement metal components in aerospace and ground vehicle assemblies, often serving as low-friction, non-corrosive bearings or spacers in dynamic environments. The company demonstrates deep familiarity with military specification standards for material selection, tolerancing, and finish requirements, particularly in applications requiring noise reduction, weight savings, and chemical resistance. Their capability centers on injection molding, CNC machining, and secondary finishing processes tailored to meet stringent defense part integrity requirements. The contractor maintains a consistent relationship with the Department of Defense, supplying mission-critical plastic components to naval, aviation, and ground systems programs. Their work for DLA Aviation supports aircraft maintenance and overhaul operations, delivering parts that ensure mechanical reliability under extreme operational conditions. The recurring nature of these awards indicates established trust in their ability to deliver consistent quality and on-time performance for sustainment and repair cycles. Their primary industry focus is in the manufacturing of specialized fasteners and bearing components under NAICS 332991 and 332722, positioning them as a niche supplier of non-metallic mechanical elements within the defense supply chain. They serve vertical markets requiring durable, low-maintenance alternatives to metal hardware, particularly in environments sensitive to corrosion, electrical conductivity, or weight. As a small business structured as a 2L entity based in Bristol, Rhode Island, TRI-MACK operates without federal certifications but maintains a focused, geographically anchored presence in the Northeast defense manufacturing corridor. Their market positioning is that of a specialized, responsive supplier of precision-engineered plastic components for mission-critical defense systems.
