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.

New from Ruland: Inch-to-metric rigid couplings

Ruland Manufacturing now offers rigid couplings with inch-to-metric bores as a standard product, giving users a wider range of off-the-shelf couplings. This expansion is the latest addition to the company's inch-to-metric, standard coupling product line that includes seven types of motion-control couplings and universal joints. Instead of re-machining or ordering custom-made couplings, using off-the-shelf, inch-to-metric rigid couplings saves time and money.

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.

What's a magnetic GHOST fastener?

PEM® GHOST™ Fastening Technology from Penn-Engineering uses a fully concealed pinch-lock mechanism to create a secure and sleek lock with zero visible evidence of disassembly once engaged. Using a magnetic release tool on the concealed fastener actuates the internal components, unlocking the pinch-lock grip and instantly releasing the pin from the fastener. From automotive interiors to access control systems, this clever fastening tech is adaptable to many applications.

NanoSteel delivers new advanced automotive steel to General Motors

NanoSteel, a leader in nanostructured steel materials, recently announced the delivery of its first advanced high-strength steel (AHSS) to General Motors for initial testing. Designed to provide automakers with a new standard in material performance, the sheet steel is poised to accelerate vehicle lightweighting initiatives focused on affordably meeting rising global fuel-economy regulations.

Production of the material, targeted to the $100 billion-plus automotive steel market, is the result of a multi-year joint development program between NanoSteel and AK Steel Corp., an industry-leading innovator in steel product development.

NanoSteel's commercially produced automotive sheet steel overcomes the historical tradeoff between strength and formability by delivering exceptional levels of both properties at the same time (approximately 1200 MPa tensile strength and 50 percent elongation). The high strength allows designers to create parts utilizing thinner-gauge material (less weight), while the high elongation allows manufacturers to produce the newly designed parts without expensive processing techniques, employee retraining, or additional capital costs. The unique combination of properties also allows engineers the design freedom to create novel part shapes, which further reduces weight.

"Many advanced materials with outstanding properties end up abandoned because they are too hard to use or too expensive to make," says NanoSteel CEO and President David Paratore. "NanoSteel's advanced high-strength steel is designed to be both easy to produce using conventional alloying elements with standard slab casting equipment and easy to use, enabling the stamping and forming of parts at room temperature without additional manufacturing infrastructure or investment, such as that required for ‘hot' stamped parts."

What sets NanoSteel apart
NanoSteel takes common raw material constituents used to make conventional steel alloys and combines them in different ratios to create proprietary alloy chemistries.

In conventional steel, the grains and matrix that comprise the structure of the steel are measured in microns. NanoSteel's alloys are nano-structured, which means grain and matrix sizes smaller than 100 nanometers. These nano-scale microstructures produce unique mechanical and physical properties resulting in capabilities outside the known performance boundaries of existing steels.

NanoSteel's technology is a "bulk materials nano-technology," which means that raw material chemistries are composed of conventional-size constituents that do not contain any nano-size particulates. Only the post-production microstructure of the thermal spray coatings, weld overlays, powder metals, and sheet steels are nano-scale in size.

NanoSteel bases the material chemistries of its patented alloys on iron, providing a competitive cost advantage given its abundance and recyclability. The company does not use any expensive, rare, or exotic constituents.

NanoSteel follows a market-driven product development model so that basic laboratory discoveries are commercialized for large-scale industrial implementation. After selecting a material chemistry that meets a desired set of properties, NanoSteel simulates actual production processes in the laboratory so that subsequent production and performance validation trials lead to a successful product launch. All NanoSteel alloys are designed for use in mainstream industries with existing manufacturing processes and widely available commercial application equipment.
