Designing with threaded metal inserts for plastics When deciding how best to attach plastic materials or components in an assembly, designers can choose several options, including adhesives or rivets. But what if disassembly and reassembly will be necessary for the unit down the road? The practical solution: threaded metal inserts. Bob Gallagher from PennEngineering runs through your insert fastening options, processes, materials, and sizes.

Lightweight metal foam withstands high explosive round New research from North Carolina State University and the U.S. Army's Aviation Applied Technology Directorate shows that stainless steel composite metal foam (CMF) can block blast pressure and fragmentation at 5,000 ft/sec from high-explosive incendiary (HEI) rounds that detonate only 18 in. away -- much more protection than all other existing vehicle armor materials while lowering the weight remarkably.

Engineer's Toolbox: Scanning vs. CMM -- A brief comparison of technologies For over 50 years, the benchmark for accuracy in measuring solid objects, whether machined, molded, die cast, welded, or forged, was the coordinate measuring machine (CMM). During the last two decades, however, a new kid in town arrived, with the power, size, point capability, and price value that leaves CMM technology in the dust.

Benefits of hybrid bearings Hybrid bearings have shown good performance in poor lubrication and contaminated conditions, but the understanding of the contributing mechanisms and their effect on performance is still lacking. SKF has developed more insight into the tribology of hybrid bearings through both dedicated experiments and modeling.

New option for flexible heater applications Rogers Corp. has introduced ARLON raPId polyimide substrates, a new, innovative solution for streamlining manufacturing and improving performance of flexible heater applications. These substrates incorporate the benefits of polyimide heater dielectrics with the flexibility and usability of a silicone adhesive system. This makes a big difference during manufacturing, because the innovative thermosetting silicone adhesive system locks the foil-etched circuit in place, minimizing circuit "swimming" during capping, while minimizing delamination and voids. This solution is ideal for high-reliability applications as a replacement for acrylic or FEP adhesives in polyimide flexible heaters.

Fast-curing thermally conductive epoxy A new Aluminum Filled Epoxy Adhesive (70-3814) developed by Epoxies, Etc. has 1,000 psi of strength in just four hours! After 24 hours, the Lap Shear Strength is 2,900 psi. The use of aluminum filler provides lower shrinkage than is commonly found in fast-curing epoxy adhesives. The product bonds well to metals, especially aluminum and steel, as well as ceramics and many plastics. It is used in many industrial, OEM, aerospace, and chemical-processing applications, including aluminum heat sink bonding, filling metal joints, repairing metal surfaces, patching aluminum castings, and assorted metal bonding applications.

Microcontroller for automotive and industrial radar systems Mouser Electronics is now stocking the S32R274 radar microcontroller from NXP Semiconductors. Engineered to meet the high-performance computation demands required by modern beam-forming and fast chirp-modulation radar systems, the S32R274 combines signal-processing acceleration with a multicore architecture to provide up to four times the power performance in industrial and automotive applications, compared to previous generations of products. This device offers a multifaceted solution for general software tasks and car bus interfacing. Combined with radio frequency (RF) front-end technologies (RFCMOS or BiCMOS), the S32R274 provides designers a scalable solution that addresses ultra-short-range, short-range, mid-range, and long-range radar systems.

| Festo creates rolling spider-like bot | |
The pneumatics wizards at Festo, famous for creating nature-inspired bionic creature concepts that also often include electromechanical drives, motors and controllers, and grippers, have unveiled the cartwheeling BionicWheelBot at Hannover Messe 2018. Like its biological model, the flic-flac spider discovered at the edge of the Sahara, the BionicWheelBot can both walk and roll. This machine rolls along the ground by forming a wheel with three legs on each side of its body. Two more legs, which are retracted during running, are then extended. When the spider is rolled up like a ball, these legs push it off the ground and propel it forward in a continuous rolling motion.
