Our close association with Defense OEMs and Prime contractors has provided us the opportunity to utilize our innovative tooling designs and molding experience. Since 1967, we have been providing composite solutions for missile, torpedoes, bunker covers, fuel sells, flight simulators for both F-15 and F-35 programs, ballistic protection covers and multiple impellers/casings for propulsion units.
