Earlier this year at Chinaplas 2006, Battenfeld displayed the HM 270/1330H/1000H, a multi-component injection molding machine that used a patented air-injection process. The machine first injects an outer skin, then a second core material and finally a gas to fill the mold. Water injection provides additional capability and even faster cooling. "You could make a tube, for example, out of a rigid plastic," says Thomas Betts, regional representative for Battenfeld. "Using water assist, you could hollow it out and then overmold it with a TPR on the end to give you a flexible hose connection." For the system designer, the water assist approach eliminates two or even three components. Although licensing is required for the patented process, the shortened cooling phase may provide justification for the added expense.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
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.
