Metal clamps are eliminated because of a new spin welding process used in the pressure line of the award-winning diesel exhaust fluid system (DEF) in the 2011 Ford Superduty pickup truck. A 50 percent glass reinforced polyamide quick connector is friction welded to a polyamide line in one of the many technical innovations in the DEF system, which won the Grand Prize at the 40th Annual Automotive Innovation Awards Gala held by the Society of Plastics Engineers International in November. The all PA12 inner tube line construction is 40 percent lighter than competitive EPDM rubber lines, according to Scott Cooper, an engineer with Ford Powertrain Engineering.
Spin welding, a technical strength at Ford, is used to join spherical plastic parts. Generation of friction at the mating surface by spinning one part (upper) against a fixtured (lower) part, fastens the assembly.
Several of the new and noteworthy 3D printers in this slideshow are breaking some boundaries in build volume, new metals printing techniques, or working with high-profile development partners to ensure very high-quality parts and controls.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
