The economy may be weak, but not the entrepreneurial spirit. A major new nylon producer emerged at the National Plastics Exposition this week in Chicago. The new producer is Invista, a company that was formed more than five years ago from assets spun off from DuPont. Based in Wichita, KS, Invista is one of the world’s largest producers of polymers and fibers, primarily for apparel and carpeting and other applications. Brands include Stainmaster carpet and Lycra apparel, both once iconic names in the DuPont portfolio. The assets were purchased by Koch Industries as DuPont repositioned into other markets-a strategy still unwinding for many chemicals companies.
Invista has been selling polyester resins, including PBT-type polyester for engineering applications. Koch had signed a five year non-compete for nylon resins. That agreement has now expired, and Invista enters the market with a lot of nylon-producing firepower. “We’re taking a more focused approach by creating a simplified portfolio of products, each with the ability to perform in numerous applications,” said Kurt Burmeister, executive vice president on Invista’s engineering polymers business. “The benefits are economics of scale and customer flexibility, due to less complex operational systems and reduce inventory requirements.” Burmeister told Design News that Invista will sell a variety of compounded nylon products using an array of toll compounders operating as contract manufacturers. Emphasis will be on nylon 6,6.
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.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
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.
