Ohio-Researchers at Battelle have developed a new, stronger method of joining materials together that conserves energy and minimizes material costs.
The patented process for Ultrasonic Injection Moulding strongly bonds polymers and does so at significantly lower temperatures than those seen in traditional bonding processes that use heat alone. The secret is a relatively low level of ultrasonic energy applied to the polymer moulding or polymer extruding process--specifically in the regions where inserts are placed or at intersections of two or more polymers.
Researchers believe the breakthrough may have the greatest impact in the automotive industry where a thin layer of high-performance, high-cost polymers can be bonded over low-cost substrates in plastic trim and body parts. Other potential applications include high-strength parts in mounting components for electronics, plastics enclosures and housings, and mechanical machinery covers and enclosures.
The combination of low cost and low temperatures is significant. Specifically, the lower temperatures allow uses with electronics that are difficult or impossible using traditional, high-temperature bonding.
""We believe this is a breakthrough with potentially significant performance improvement and cost reduction potential,"" says Lynn Faulkner, Program Manager at Battelle. ""The process improves flow and mould filling, removes gas bubbles from the mould, eliminates cold bonds, and allows incorporation of filler materials.""
ZSK will hold its bi-annual technology showcase on 21-22 September 2018 at its Krefeld, Germany, headquarters. The Embroidery Technology Show assembles more than 25 exhibitors from around the world to discuss emerging trends in the embroidery manufacturing industry and demonstrate the latest products produced using techniques such as tailored fibre placement (TFP) or smart textiles.
SGL Carbon and Fraunhofer IGCV have officially opened the Fibre Placement Centre (FPC) at SGL's site in Meitingen, Germany. Compositence, BA Composites and the Chair for Carbon Composites at the Technical University of Munich have also joined the alliance, and Coriolis Group and Cevotec are planning to come on board as partners.
Fibrelite reports that since the start of its partnership with Trenwa more than 100 precast trench systems integrating Fibrelite composite covers have been sold for use in electrical substations, wastewater treatment plants, chemical refineries and many other applications across North America.
