Delta Unveils World’s First Anti-Microbial Cooling Tower November 26, 2016 (Roxbury Twp., NJ) Legionella, the bacteria that causes potentially fatal Legionnaire’s Disease, and other strains of deadly pathogens that are hosted by some cooling towers, have been substantially reduced by the development of a unique anti-microbial HDPE material introduced by Delta Cooling Towers (deltacooling.com) on September 1, 2016.
Companies Push the Boundaries of 3D Printing Composites October 26, 2016 Entrepreneurs and existing manufacturers are making 3D printers that automate production of composite parts, and are unique in their design.
Hard Titanium-Gold Alloy Ideal for Artificial Joints October 5, 2016 Researchers at Rice University (Houston) have discovered a titanium-gold (TiAu3) alloy that is harder than most steels and may be an optimal choice for use in orthopedic joint replacement surgery.
Searching for the Perfect Lightweighting Recipe September 1, 2016 Lightweighting is so established it’s now part of marketing for new vehicles. Automakers routinely detail how much less models weigh than their predecessors. General Motors Co., for example, has said a range of its vehicles is anywhere from almost 250 lb (112.5 kg) to 700 lb (315 kg) lighter.
No Two CFRP Materials Machine Exactly Alike August 31, 2016 Carbon fiber reinforced polymer (CFRP) composite materials deliver the important performance advantages of high strength-to-weight ratio, durability, and extreme corrosion resistance in lightweight structures, valued especially for demanding aerospace and oil and gas industry applications.
3D-Printed Parts Restore Cars’ Glory August 12, 2016 Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.
Metals Testing Requires Escalation-Based Strategy August 14, 2019 At Cary Rosenberg’s company, Watts Water Technologies, validating material properties to ensure they are composed of the correct elemental composition is an important part of their work.
Geometry, Parameters, and Strong Toolholders Vanquish Drilling Problems June 3, 2019 Proper drill selection, the geometry built into the drills themselves, applying proper drilling parameters, and a few tips and tricks from the pros can address nagging drilling problems such as drill breakage, unbroken chips, tool runout, poor hole edges, and poor tool life.
Bridge Tool & Die: CNC Turns ‘Feel’ Into High-Precision Carbide Grinding November 28, 2018 Glenn Bridgman describes the difference between his shop’s manual grinders and its newest state-of-the-art CNC ID/OD grinder, a Studer CT960 OD/ID from United Grinding (Miamisburg, OH), as “feel vs. facts.” Bridgman, president of Bridge Tool & Die (Buckley, MI), believes that manual grinding is a somewhat personal operation.
Testing the Metal November 27, 2018 Materials science has opened new possibilities for designers of cars, planes and other products. Metal alloys are now as precisely engineered as they are machined. The result is longer lasting, stronger parts. But with a wider selection of materials comes risk—how can you be sure that one piece of gray metal stock is different than another? Careful warehousing procedures and paperwork only go so far.
