Who knew? How colorants affect plastic
In plastic injection molding, one aspect of polymer characteristics that doesn't always get the consideration it deserves is the addition of colorant. Believe it or not, there is a whole scientific body of knowledge about the ways in which adding color to plastic can affect its behavioral properties. This short article by Denny Scher of ICO Mold takes a high-level look at some of the different, and surprising, ways colorants can affect plastics.

Smart fixed flange bearings unlock predictive maintenance
igus has developed intelligent two- and four-hole fixed flange bearings with wireless sensing capabilities for wear detection. Constructed from self-lubricating, high-performance plastic, the bearings feature an integrated abrasion sensor, thin circuit board, and cableless battery supply. Wear interrupts the board's conductor paths, causing the electronics to lose the signal. The sensor then transmits a long-range network signal to an igus i.Cee switch cabinet module for analysis, including the percentage of abrasion.

70% longer service life for linear bushings
As a result of an optimized production process, Bosch Rexroth's segmental linear bushings with plastic cage used in a wide variety of industries achieve a load capacity that is up to 20% higher and a service life that is up to 70% longer. They are part of a Rexroth round guide with a matching shaft. The increase in load capacity makes it possible to use a smaller size in many cases while meeting the same requirements. Downsizing reduces system costs, saves space, and reduces weight.

Oshkosh Defense shows off high-performance, production-ready Joint Light Tactical Vehicle
Just weeks after successfully completing the U.S. Government's Production Readiness Review (PRR) for the Joint Light Tactical Vehicle (JLTV) program, Oshkosh Defense showcased its JLTV solution -- the Light Combat Tactical All-Terrain Vehicle (L-ATV) -- at the Association of the United States Army (AUSA) 2014 Annual Meeting and Exposition in Washington, D.C., Oct. 13-15.
"Oshkosh Defense is ready for JLTV production," said U.S. Army Major General (Retired) John Urias, executive vice president of Oshkosh Corporation and president of Oshkosh Defense. "We are very confident about producing high-quality JLTVs on schedule and on budget, because no other OEM has launched more successful tactical wheeled-vehicle production programs than Oshkosh."
In 2013, the company produced its JLTV EMD prototypes on an active and proven production line, right alongside its MRAP All-Terrain Vehicle (M-ATV), Family of Heavy Tactical Vehicles (FHTV), Family of Medium Tactical Vehicles (FMTV), and other platforms. Using lean processes, flexible assembly lines, an experienced workforce, and rigorous quality checks, Oshkosh has successfully delivered a full range of military vehicles for decades.
The Oshkosh L-ATV's lightweight, compact design leverages 10 years of research and development, as well as lessons from decades of field operating experience. L-ATV merges key design elements of highly survivable combat vehicles and off-road tactical vehicles to operate in a range of threat levels and terrains. Features include:
- The Oshkosh TAK-4i intelligent independent suspension system is the next generation of the world's most advanced, combat-proven suspension system, TAK-4. The TAK-4i system provides Warfighters with unprecedented maneuverability and a smoother ride to reduce fatigue after traveling the world's toughest terrains.
- The Oshkosh Core1080 crew protection system is an integrated system designed to absorb and deflect blast energy. It is a multi-faceted, fully integrated survivability system that applies advanced components and materials to save lives. The Core1080 approach has been proven on multiple vehicle platforms and credited for saving thousands of troops' lives over the past decade during missions outside-the-wire.
- Whether traveling over hazardous terrain or unpaved roads, the L-ATV's digitally controlled engine maintains steady, fuel-efficient power without sacrificing the acceleration and cruising speed that Soldiers and Marines need in high-threat environments. The vehicle's power-to-weight ratio is optimized to provide superior acceleration, mobility and speed on grade capability.
- L-ATV's Net Ready systems integration brings critical network and computing capabilities to a broader range of ground missions. L-ATV's advantage is based on a unique combination of vehicle OEM expertise and extensive in-house C4 and systems capabilities at Oshkosh. L-ATV was designed from day one as a "tactical vehicle system" that optimizes the user experience and ergonomics while maximizing overall system performance.
Oshkosh Defense's JLTV solution also features a variety of sophisticated on-board technologies, including an Interactive Electronic Technical Manual (IETM) and a vehicle Health Management System (HMS).
