The news is full of bankruptcies at shoot-and-ship plastics processors, particularly those who serve the price-focused automotive industry. But if you have a specialty, business is great. Take for example, Micromold Products of Yonkers, NY, which specializes in production of PTFE and PVDF parts for handling of corrosive liquids. There’s technology in the design as well as in the handling of the materials. Two patents for fluid handling show the trend. PTFE, either compression molded or formed from shapes, replace glass, which is extremely brittle, inflexible, and subject to manufacturing imperfections. Other proprietary technology is used in the fusion process. PTFE has a high coefficient of expansion and the lowest coefficient of friction of any known solid material. Micromold was started in 1950 by a former scientist at DuPont, where PTFE was commercialized as Teflon. One thing interesting about Micromold: Despite its name, it does no injection molding. Why the name? “That’s lost in the mists of time,” laughs Claude Berman, engineering manager. Micromold’s sales are up about 30 per cent in the past three years.
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.
