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.

Dual injection gets even better: Bosch, Ford, and TI Automotive recognized with 2017 PACE innovation award

Bosch, Ford Motor Company, and TI Automotive were recently recognized with a 2017 Automotive News PACE (Premier Automotive Suppliers' Contribution to Excellence) Innovation Partnership Award for their collaboration to develop the Port Fuel and Direct Injection System (P-DI). The P-DI system was also named a 2017 Automotive News PACE Award finalist for a product and process innovation, along with Bosch's Engine Compartment Actuator (ECA), extending Bosch's long history of PACE Award recognition.

P-DI is a dual injection system that takes the best of traditional port injection and combines it with the latest gasoline direct injection technology to deliver exceptional performance across the engine's whole operating and load range. The result is a power plant with enhanced performance in the areas fuel economy, emissions, high torque, and power output.

The Innovation Partnership Award was presented during the annual 2017 Automotive News PACE Awards ceremony held on April 3 at the Max M. & Marjorie S. Fisher Music Center in Detroit. It was given for the outstanding level of collaboration between the original equipment manufacturer (OEM) customer and supplier.

"Strategic partnerships like the one Bosch has forged with Ford and TI Automotive are only made possible through dedication, trust, teamwork, and with an eye toward a singular goal: to provide an innovation that will propel the industry forward in new ways," said Mike Mansuetti, president of Robert Bosch LLC. "That's precisely what we've accomplished in working with Ford and TI Automotive to implement the first Port Fuel and Direct Injection System with a North American customer on the all-new second-generation Ford 3.5 Liter Ecoboost engine."

This application was achieved through intense tri-lateral cooperation between Ford, TI Automotive, and Bosch in the areas of design, development, and packaging of the P-DI system. The project required technical collaboration, exchange of expertise, and expanded system-level validation testing to realize Ford's innovative design targets. These requirements took this partnership beyond the customary sphere of collaborative practices in the industry.

The key challenge of the project was to bring the two fuel systems (low and high pressure) together in an environment that had traditionally accommodated only one. In order to deliver Ford an effective packaging solution, the three companies worked closely together to optimize the packaging of the two fuel injection systems, maintain proper fuel metering accuracy, implement design features to attenuate hydraulic pulsation in the rail, and prevent potential cross-talk between the two systems.

Bosch has a rich history of honors in the Automotive News PACE Awards competition. In addition to be honored as a finalist for product and process innovation in 2017 for its ECA and P-DI technologies, Bosch was a 2016 winner for its Linear Force Solenoid (LFS) technology, which enables transmission manufacturers to develop more efficient, high-speed transmissions. Bosch was also a winner of a 2014 award for its laser-drilling technology for spray enhancements in gasoline direct injection, and it garnered back-to-back awards in 2010 and 2011 for its innovative collaboration with Bombardier Recreational Products Inc. and its P2 Parallel Full Hybrid System, respectively. Bosch was also an Automotive News PACE Award finalist in 2014 for its open source-based infotainment system solution; in 2011 for its windshield wiper direct drive system; and in 2010 for both its Long-Range Radar and Vehicle Stability System.
