Opel is in the news almost weekly for financial reasons. But the German-based subsidiary of General Motors is also making some technical news. Opel joined with Recaro, a Tier II seat maker, and BASF to develop an all plastic car seat that eliminates the requirement for a steel frame.
The seats are low weight while offering high mechanical strength, good ergonomic properties and a sporty look. The seat pan is made of Ultramid B3ZG8, a very tough yet stiff PA6. Ultramid B3G10 SI is used in the large, free-standing backrest shell as well as in the crossbar. The insert for the backrest shell is made of Neopolen P 9225 K (EPP), an energy-absorbing foam that also covers edges and serves as a module carrier for motors and seat components such as the spinal column support.
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.
