Nylon producers are looking for their next Holy Grail. Most of the world’s global nylon goes into fiber, where polyester is gaining favor. Also weak is the auto market, a major outlet for engineering grades of nylon. Pundits say operating rates for nylon output could be as low as 80 percent for the next four years. Development of injection moldable nylon air intake manifolds gave nylon an enormous boost in the 1990s-to say nothing of the benefit in auto design. In 1960, the average car used just 0.4 pound of nylon. Most applications were noncritical, such as valve stems or bushings. By 2000, the average car used 11 pounds of nylon.
GM’s 3800 Series II V-6 engine in 1995 featured the first thermoplastic oil pan gasket with an integrated windage tray molded of nylon 66. In 2008, Daimler introduced the first production oil pan module made from nylon. Both DuPont and BASF have developed special optimized grades that could boost use of nylon for oil pans. The big issue was punishment from flying highway stones. New U.S. fuel guidelines may be just the impetus needed to get the momentum really moving for nylon. In the today’s stimulus parlance, this technology is shovel ready.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
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.
