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.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
