There was plenty of evidence throughout the halls of National Manufacturing Week held this week in Rosedale, IL that the medical market will become increasingly important to the U.S. economy. Teknor Apex, for example, unveiled 33 Medalist compounds all tested for compliance with ISO 10993-5 cytotoxicty standards and free of animal-derived materials, vinyl, phthalates and latex. Removal of animal-derived materials, such as stearates, derives from fears related to mad-cow disease, says Lisa M. Charno, market manager for the thermoplastic elastomer division at Teknor Apex. Another exhibitor, Elite Mold & Engineering purchased two all-electric injection molding machines to pave the way into the growing medical device market. “We believe this market will eventually account for 75 percent of our business,” says Joseph Mandeville, president of the Michigan molder. An interesting new technology for medical devices has been enhanced by another exhibitor, Saint-Gobain Performance Plastics. Two-shot molding is now becoming a factor in the medical device market because of new commercial grades of USP Class VI self-bonding silicones. They bond to rigid thermoplastics in the mold, avoiding costly secondary operations.
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.
