To address the cost crunch for diaphragms, Minnesota Rubber proposes LSR for its strength and flexibility. "Liquid Silicone Rubber thin-wall diaphragms are an excellent example of a very cost-effective replacement for fabric reinforced diaphragms," says Ted Ahrenholtz, senior design engineer, Minnesota Rubber. LSR's durometer rating from 20 to 80 Shore A and its tensile strength of 1150 to 1750 psi, combined with heat resistance to +180C and flexibility down to -45C, make it a good choice for pneumatic gauges in automotive and truck applications. With a clean molding process and no material pre-processing, molded parts typically have very little gate or flash material waste. In addition, compared to other materials and processes, LSR's repeatable, short cycle times and reduced or eliminated secondary operations provide lower labor cost.

In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
