One of the hot new ideas in material’s joining is use of atmospheric plasma. Plastics, metals, glass or textiles are cleaned, activated or coated with Openair Jet-Technology, replacing adhesives or mechanical approaches. It’s Physics 101: apply energy and the state of matter changes. Solid turns into liquid, and the liquid becomes gas. If more energy is applied to the gas, electrons leave their atomic shells, putting the gas into the plasma state. Plasma is generated by an intense pulsed arc discharge from a jet that can operate as part of an in-line manufacturing system. The working gas typically is dry compressed air. The breakup of atomic bombs allows cleaning and joining of dissimilar materials.
Developed by Plasmatreat, the first breakthough came in 1995 with the pretreatment of headlight housings, and applications now includes windshields, engine control housings, displays or sensors and the bonding of body components.
Look for the process to become more widely used in multicomponent injection molding processes, which previously had to avoid use of low-priced polypropylene. PP doesn’t adhere well to TPU when treated with plasma. As a result, alloys of polycarbonate and ABS are often used, The PP-TPU system is a result of a collaboration between Plasmatreat, Krass-Maffei, the University of Erlangen-Nŭrnberg, and Neue Materialien Fŭrth.
Read a report of a new technology demonstration at the upcoming Fakuma show in Germany.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
