POLYTECHNIC INDUSTRIES, INC

Manufacturing and Distribution of Military Spare Parts

These 36” long heavy duty springs are used for recoil suppression on a projectile launch system. We manufacture small and large springs.

This assembly contains castings, screw machine parts, precision ground components, five different materials, and lots of complex machining.

This close-up shows a matched set consisting of a large spur gear and a mating worm wheel.  It is just one example of the diverse gear manufacturing capability we possess.
