Spirolox® Retaining Rings
Spirolox retaining rings have no ears to interfere with mating components and are manufactured by coiling the ring from flat wire. Because coiling produces a retaining ring with no scrap, the Smalley Retaining Ring can be economically produced in carbon steel, stainless steel, coppers, and many other alloys.

World’s Smallest Stepper Motor is a Big Win
MICROMO presents the FAULHABER FDM 0620 series stepper motor. Measuring just 6mm in diameter and 9.7mm in length, including all components and connections, and with a 0.25mNm holding torque rating, the FDM 0620 stepper motor series is small enough to fit in the most compact spaces for limitless applications. This micro stepper motor is also now available for purchase online with and without leadscrew options.

Wheels: Magnesium car parts get lighter, brighter future
A new process developed at the Pacific Northwest National Lab should make it more feasible for the auto industry to incorporate magnesium alloys into structural components by reducing costs and improving the material's structural properties -- and also make the material a viable alternative to aluminum.

Army developing lasers that pierce fog, dust to destroy targets
A lot of people think that high-energy lasers, or HELs, can't penetrate fog, rain, and dust. That's just plain wrong. The key to making HELs work in poor atmospheric conditions is something called "adaptive optics," which the Army is continuing to improve to give a greater range of compensation for degraded conditions.

Breakthrough made in 3D-printed marine-grade stainless steel
Researchers at Lawrence Livermore National Lab have made a major achievement in 3D printing one of the most common forms of marine-grade stainless steel (316L) that promises an unparalleled combination of high strength and high ductility for the ubiquitous alloy. Better yet, the new material outperformed samples made with the traditional approach.

Robotic Spot Welding Force Measurement
Spot welding requires clamping force control during the welding process to ensure a clean joint and prevent flaw formation. For robotic platforms, this requires sensors to measure contact force during the joining process. A load cell installed in-line with the actuator measures the grip force of the welding tongs during welding.
Learn how load cells are used in this and other applications.

C-Solder enables joining of carbon materials

Wow, you can probably file this under, “I really haven’t heard of that before!” Materials specialist Goodfellow has just released a new tin-based, flux-free soldering alloy called C-Solder that enables the joining of carbon materials in both carbon-carbon and carbon-metal combinations. Using a classic soldering iron, heat gun, or torch, the resulting bond is both mechanically strong and electrically conductive. But what can you do with it? With C-Solder you can join carbon materials, including carbon fibers or carbon nanotube fibers in carbon-carbon arrangements; carbon to metals (e.g., copper aluminum, titanium, stainless steel), ceramics, and glass materials; and aluminum to aluminum without using flux. This lead-free product has excellent flow, does not leave a residue, and is not flammable.

5 ways to master complex features in injection-molded parts

Designing for plastic injection molding is like raising teenagers -- some parts (and some teens) are more challenging than others. But by following a few simple rules, even the most difficult of these challenges can be overcome. For injection molding, there are some common troublemakers during part design. Proto Labs runs through how to handle them.

Biggest reasons engineers hate their CAD system
Darren Garnick of Onshape says that, in a recent CAD satisfaction survey of 230 design professionals, Engineering.com asked a very provocative question: What do you hate most about your CAD software? The research, sponsored by SOLIDWORKS®, revealed these four things that engineers and designers despise the most (in order of importance).

Fasteners: Self-clinching free-running locknuts with modified threads
New PEM S-RT self-clinching free-running locknuts from PennEngineering feature a modified thread angle enabling easier tightening of mating screws and superior vibration-resistant locking performance in thin metal assemblies. The modified thread formation allows mating screws to spin freely during the attachment process until clamp load is induced during the screw-tightening process. The applied clamp load then engages the locknut’s vibration-resistant locking feature, which securely and reliably locks the screw in place. Compared with traditional locknuts, excellent joint clamp load remains consistent, even after many on/off cycles.

Mystery of Civil War sub crew deaths solved scientifically?
When the Confederate submarine HL Hunley was raised from the ocean floor in 2000, the skeletons of its eight crewmembers were found seated at their respective stations with no physical injuries or indications that they were attempting to escape after sinking the Union ship Housatonic on February 17, 1864 -- and then sinking themselves. What happened?

20th anniversary of supersonic car land speed record
On Oct. 15, 1997, the British Thrust SSC team set the World Land Speed Record of 763.035 mph -- making it the first and only car to reach speeds faster than the speed of sound. Driver Andy green, also a Royal Air Force fighter pilot, describes in detail what it was like to make the historic final run and keep this awesome twin-engine machine on the ground in Nevada and on a straight course. Currently, Green is prepping to set a new land speed record of 1,000+ mph in the BLOODHOUND SSC jet-engine car in South Africa in 2019. Fascinating!

See world's most efficient aero engine assembled
It takes more than 20,000 components perfectly fitted together to build the world's most efficient and fastest-selling wide-body jet engine, the Trent XWB. See how it is done at Rolls-Royce's assembly plant in Dahlewitz, Germany. The A350-1000 is the latest member of Airbus’ leading wide-body family to use the engine line. The newest iteration provides 97,000 lb of thrust and includes new high-temp turbine technology, a larger engine core, and advanced fan aerodynamics.
