One of the themes at the Medical Design and Manufacturing West event being held this week in Anaheim, CA is tiny. Medical devices are becoming smaller. That’s putting a lot of pressure on suppliers to provide precise tolerances. One of the interesting examples of the trend is a display from Kyocera showing its capability to achieve dimensional tolerances of ±0.002-inch on powder molded ceramic parts used in electro surgical devices. Kyocera can also achieve ±0.01-inch minimum wall thickness, says Hideki Ohnishi, manager of fine ceramics marketing at Kyocera. Achievement of the precise dimensions is possible because of custom made powder slurries as well as tweaking of the injection molding process, according to Ohnishi. Particular attention is paid to gate locations and venting. Kyocera operates 15 injection molding machines in Japan for the ceramic process. Ohnishi said that Kyocera will be almost doubling capacity due to strong demand for the products. Press sizes are 30 or 60 tons of clamping force. Typical part sizes are half-inch cubes.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
