Interested in mechatronics? There are some very cool examples coming out of Germany using a plastics process called “outsert” molding. In outsert molding, plastic pieces are molded into a frame of metal or some other material. Two examples are new infusion pumps made by medical device OEM B. Braun of Germany. The process begins with the creation of a frame for the pump that consists of a chassis, bolt, flap and pump chassis. High-performance plastic parts are molded onto the plate in a one-shot process. The biggest advantages are part reduction (up to two-thirds) and elimination of secondary operations. The Braun parts are made at the TB&C Outsert Center in Herborn, Germany. TB&C’s use of outsert techniques dates to 1985 when its parent, Phillips Metallwaren, was forced by Asian customers to dramatically reduce costs on car auto tape drives. TB&C says reject levels with the process are low at 25 ppm. Electromechanical structures are molded by TB&C for large roof systems, automated teller machines as well as mediacl devices with microtransmission.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
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.
