Interested in mechatronics? There are some very cool examples coming out of Germany using a plastics process called “outsert” molding. In outsert molding, plastic pieces are molded into a frame of metal or some other material. Two examples are new infusion pumps made by medical device OEM B. Braun of Germany. The process begins with the creation of a frame for the pump that consists of a chassis, bolt, flap and pump chassis. High-performance plastic parts are molded onto the plate in a one-shot process. The biggest advantages are part reduction (up to two-thirds) and elimination of secondary operations. The Braun parts are made at the TB&C Outsert Center in Herborn, Germany. TB&C’s use of outsert techniques dates to 1985 when its parent, Phillips Metallwaren, was forced by Asian customers to dramatically reduce costs on car auto tape drives. TB&C says reject levels with the process are low at 25 ppm. Electromechanical structures are molded by TB&C for large roof systems, automated teller machines as well as mediacl devices with microtransmission.
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.
