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.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
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.
