A North American manufacturer will be one of the show stoppers at next month’s Fakuma injection molding fair in Friedrichshafen, Germany. Trexel of Woburn, MA, will show how long-fiber reinforced plastics can be used in its microcellular foam process called MuCell. The MuCell process produces lower cost engineering parts with high quality and exceptional dimensional stability in applications where foaming has not historically been deployed. The long fiber technology from Ticona works well for large and complex parts. New parts use an advanced screw design developed jointly by Trexel and Ticona. Hartmut Traut, business director - Europe of Trexel, said several benefits result. “These include potential weight savings of 10 percent, and a 10 to 20 percent cycle time reduction. In addition, customers can get these benefits along with reduced warpage compared to solid injection molding and prior iterations of the MuCell process,” says Traut. One advanced American user of MuCell is fastener maker Soutcho, which uses injection molding machines sized from 55 to 350 tons in clamping force to make MuCell parts.
University of Southampton researchers have come up with a way to 3D print transparent optical fibers like those used in fiber-optic telecommunications cables, potentially boosting frequency and reducing loss.
The first ASME Additive Manufacturing + 3D Printing Conference (AM3D) will be co-located with the organization's International Design and Engineering Technical Conferences (IDETC) and Computers & Information in Engineering Conference (CIE), Aug 2-5 in Boston.
