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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
