These injection molded filters made for the medical market have more than 1,000 76-micron (0.003 inches) squares with wall thicknesses of 0.006 inches. "The previous way to make a filer was to run a metal mesh through an injection mold and then mold a frame around it," comments Donna Bibber, vice president of sales at Miniature Tool & Die. The trend to minimally invasive surgery is triggering a boom for micro components that travel through blood vessels. "Everywhere we turn there is a challenge we have to overcome,"
comments Bibber, a plastics engineer. Example: MTD had to develop a 7-gram hopper for resin drying. Conventional dryer hoppers are in the 150- to 200-lb range. "Also, we don't always have the luxury of a surface we can eject on to," she adds. MTD often ejects from runners or gates. For more information, go to http://rbi.ims.ca/4922-503.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
