Precision Manufacturing for Aviation & Defense Applications

SIS supplies rigid, precision-machined components used in aircraft systems, defense equipment, and military shelters. Our parts provide critical support, insulation, and protection in high-temperature, high-load, and mission-critical environments. SIS products are built from advanced thermoplastics, thermosets, and composites, with commonly machined materials including PEEK, Nylon, Acetal, acrylic/PVC alloys, PPE, and many other engineered plastics.

Each component is manufactured to precise specifications to ensure aviation and military-grade performance without compromise.
