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.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
