One of the best showcases in new plastics technology is the annual competition in automotive plastics held by the Society of Plastics Engineers. This year’s grand prize, announced last night, went to General Motors for backlighting using color-converting plastic in the Tahoe SUV. The patented system for producing custom-colored interior backlighting via LEDs (fed through light distribution pipes) uses fluorescing dyes and proprietary light-scattering additives in translucent resins used to mold buttons, knobs, and backlit plates rather than expensive custom-colored LED bulbs. The change in color control makes backlighting in low-volume, niche colors economically feasible. The system supplier is Delphi Electronics & Safety with material from RTP, BASF, and Bayer MaterialScience. The tool was made by Kno-Mar Tool in Clearwater, FL.
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.
