Additives are an area where design engineers could focus a little more time and attention. When added to plastic resins, these chemicals impart a needed property and they also change the mechanical characteristics of the compound. There are also new technologies emerging that can save time and money. One I saw recently comes from Carolina Color of Salisbury, NC. A new process creates so-called “super concentrates”. “G2 has overcome processing challenges with a proven ability to provide exceptionally effective dispersion and distribution in both large and small parts,” says President Matt Barr. The new G2 product line is claimed to save up to 30 per cent in color cost and allow processing at lower temperatures, which can save up to 10 percent in cycle time. Part thickness can even be reduced because of improved physical properties. That also means reduced cycle time and clamping force. It’s worth a look.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
UL is partnering with metals additive manufacturing (AM) supplier EOS to provide AM training to EOS's customers. It's designed to promote correct usage of AM technologies by OEMs and others in manufacturing.
To commemorate Earth Day, we take a look at the state of ocean plastic. If things don't change, by 2050 the oceans will contain more plastic than fish by weight. Here are the problems, as well as some solutions.
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.
