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.
How 3D printing fits into the digital thread, and the relationship between its uses for prototyping and for manufacturing, was the subject of a talk by Proto Labs' Rich Baker at last week's Design & Manufacturing Minneapolis.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
