A customer in the aerospace industry needed a company with the experience and technology to construct a uniquely designed venturi tube for a helicopter heating and air conditioning application. Elyria Metal Spinning was hired to complete the required work, drawing from over 40 years of experience to spin the part from tubing. The saw cutting tube was drawn from ASTM B210 6061 series 0 3" OD x .049" wall aluminum, and the part was constructed employing hand spinning techniques to meet the specified contours. All outside diameter surfaces were refined with precision machining techniques, and the part was trimmed to length. A deburring procedure was carried out for the effective smoothing of the unit, and the brushed finish was achieved with a scotch brite polish.

Completed dimensions of the tube were 15 ½" in length and 3" in diameter, produced while holding a tight ±0.005" tolerance. Accuracy and dimensional integrity were ensured with in process and postproduction visual inspections. Turnaround time for this project was 6 to 8 weeks, with 50 to 75 units shipped per order to the customer in Addison, Texas.
