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.

Press brake manufacturers have responded to industry’s need to produce small batches of parts that require frequent tooling changes by designing options and systems to reduce setup time by managing, storing, and automatically changing upper and lower tools. Operators can spend less time physically involved with setup and more time with the profit-making bending process. Reduced margin for error and less scrap are added benefits. However, there are steps that can be taken to reduce setup time without investing in new press brake equipment.
