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.

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.

Control Rods, Struts and Braces LeFiell's swaging machines can swage tubing from almost needle size to 18" diameter and solid bar up to 4.50" diameter. Induction heating equipment is utilized when necessary. LeFiell has the inhouse capabilities to manufacture control rods, struts and braces. These processes include swaging, Roll-Flo, heat treating and machining.

Our proprietary "RotoDraw" tube-forming process was developed and perfected by LeFiell to support the quality standards required to manufacture nozzle coolant tubes for liquid fuel rocket engines. This tapered draw process can produce tubing configurations from .080" - 2.00" diameter and from .006" - .030" wall over lengths of up to 10-feet.

The LeFiell Advantage is 30 years of experience building thousands of spar systems that have visited literally every port in the world. Our spar plan files consist of prints for boats from 20' to 70', including sloops ketches, schooners, and multihulls... Whether racing or cruising, you can rely on the LeFiell Advantage.

LeFiell has the capability to both swage and rotary forge countless tubing configurations and solid bar stock. Whether your needs require the precision swaging of needle-size tubing, the complex contour and variable-wall forming of tubes up to 5 inches i n diameter, or the rotary forging of tubes as large as 18 inches in diameter, LeFiell is fully capable of meeting your objectives.
