Kadaladex® polyethylene naphthalate (PEN) film from DuPont Polyester Films was used in audio speakers using ferrofluids to dissipate heat from the voice coil. Film tested in both ester- and hydrocarbon-based ferrofluids at 125C showed virtually no change in properties, mass, or dimensions, and the fluids themselves were unaffected, the company says.
EverLastTM high heat-resistant, printable ceramic label materials from Imtec Inc. are pre-printed and fired and allow for automatic identification and data collection with all bar code symbologies. The materials are offered in a variety of structures, which allows for in-process identification, with temperature resistance extremes from -300 to 2,550F. Applications include those subject to mechanical shock and harsh environments, such as heat transfer processes and chemical treatments.
Spectar® copolyester from Eastman Chemical Co. can be recycled and incinerated, meeting environmental requirements. The copolyester is a second-generation PETG that addresses the need in the heavy-gauge sheet market for a higher-clarity resin less expensive than polycarbonate and significantly tougher than acrylic sheet, the company says.
S-2 silicone cleaner and surface-prep solvent from Dow Corning Corp. is a non-aqueous formulation based on volatile methysiloxane (VMS). The fluid can help companies reduce overall process emissions and simplify record keeping. Lab analysis confirms no-toxic constituents, ozone-depleting compounds, and no contribution to global warming.
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.
