There’s a cool new backlighting technology on display at the 63rd International Motor Show (IAA) in Frankfurt, Germany. The instrument luster on BMW’s new 5-series features inverse forming technology for three-dimensional black panel film that has no distorted effects. In conventional thermoforming, thinning occurs at certain places on the film causing polarization in these areas in the form of rainbow-like distortions known as Newton’s rings. Achim Hosenfeld, vice president electronics at Johnson Controls, says: “Unlike before, the film is placed down into the forming tool. The result is a special embossed surface structure that is imprinted by the texture of the tool. This eliminates the need for an expensive anti-reflective coating and also makes the display easy to read.”
The black 3D film produces a smooth transition between the flat printed surfaces of the analog instruments and the digital information display.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
