EBE Reduced Raw Material and Tightened the Production Belt for Fat-zapping Device

May 14, 2015

By:

Production difficulties due to the complex design of a heat exchanger for ZELTIQ® Aesthetic Inc.’s CoolSculpting® equipment designed to selectively reduce fat caused the company to fall behind on shipments. A redesign by Electron Beam Engineering Inc., Anaheim, Calif., reduced the amount of 5052 aluminum needed by about 15 percent, simplified production for a 20 percent time savings, and upped quality to over 99 percent. The 15-in.-long electron beam welds are pressure-tight, narrow, and do not require postweld finishing.
