ROCKET

Liquid Thrust Chamber Coolant Tubes
LeFiell pioneered, designed and produced the first equipment and developed a process called Roto-Draw to produce thrust chamber tubes for our space programs. Roto-Draw's ability to hold dimensional accuracies has not been equaled by any other known tube tapering process. As a result, LeFiell has the prestige of producing thrust chamber tubes for every major liquid engine produced in the United States and Japan.

MISSILE

Missile Cases
LeFiell has the complete facilities to manufacture missile cases by two major processes: Roll-Flo and Forming. Roll-Flo is a modern age, high production chipless machining process through the plastic deformation of metal by coaxial rolling over a hardened mandrel. Drawing and Forming is performed in a variety of hydraulic presses up to 3250 ton capacity.

High Temperature Tubing and Components
LeFiell is the leader in the production of ultrasonic quality tubing produced to virtually zero defects for the aerospace industry. Tube hollows of nickel based and titanium alloys are x-rayed and redrawn in our specialized tube drawing equipment utilizing in-house heat treating equipment to control sophisticated time to temperature and time at temperature cycles.

Engine Shafts
LeFiell has a 3250 ton press and facilities to perform heat treating and rough machining operations. We have one of the largest and most modern facilities producing gas turbine engine shafts in the world. Our facilities allows us to perform upsetting, expanding, flaring, backward extruding, swaging and Roll-Flo (chipless) forming. We have produced engine shafts from the following materials: aircraft alloy steels, nickel based and 6AL-4V titanium.
