Size, geometry and cost constraints posed problems for design engineers at Gyrus Medical in Minneapolis MN, when designing the jaws for a single-use bipolar open-forceps surgical instrument that uses RF energy. Tight tolerances over the length of the part (about 4.5 inches) were also an issue. The instrument will only perform properly if the surfaces remain parallel. Gyrus looked at casting and machining before choosing metal-injection molding. "Any time we need that kind of accuracy, we're going to look for a MIM-molded part," says Craig Stowell, director of engineering for Gyrus Medical. Phillips Plastics developed custom ceramic fixtures to support the parts to eliminate sagging during the production process. The parts then went through a calibration process to meet final print specifications.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
