Engineering Ceramics Ideal for High-Temperature, High-Wear Applications
More durable than metals and highly resistant to extremely aggressive environments, engineering ceramics are typically used for aerospace, automotive, military, electronic and industrial applications. Goodfellow's line of engineering ceramics includes but is not limited to alumina, boron nitride, and zirconia and is available in a wide range of forms (rod, sheet, foam, powder, crucible, etc.) or as finished components precision-machined to customer drawings.

New Navy 3D-printed antenna designs reduce cost, weight, size

Engineers at the U.S. Naval Research Lab are creating and testing 3D-printed antennas and arrays that can be produced in hours instead of the days and weeks it usually takes to machine and assemble new units.

Automotive Industry First:
ExOne binder jet aluminum 3D printing qualified by Ford

In a project co-funded by Ford and ExOne, a team of engineers, material scientists, and manufacturing experts has developed a patent-pending process for rapid and reliable binder jet 3D printing and sintering of aluminum 6061 -- one of the most commonly used aluminum alloys in the world. The new process delivers final parts with 99% density and material properties comparable to die casting.

New inexpensive battery has 10-min. charge for EVs
A new thermally modulated and cobalt-free battery for mass-market electric vehicles can reduce range anxiety while providing unsurpassed safety at a low cost. Developed by a team of Penn State engineers, it can charge for 250+ miles in 10 min. and is powerful enough to accelerate an EV from 0 to 60 mph in 3 sec.

All-new Ford Raptor 2021: Grown up but still a rebel
The Ford Raptor line hit the scene in 2009 as the ultimate off-road pickup. Like a rebellious, brawny teenager, the high-performance F-150 was brash, fearless, and unapologetic -- ready to jump and to catch some air. Sitting on 37-in. tires, the all-new 2021 third-gen F-150 Raptor is stronger and can take more licks with its updated suspension, but it's smarter and more sophisticated too.

Precise motion for optics and thermal imaging
From scanning buildings for heating and cooling "leaks," to scanning people at the airport for possible fever, thermal imaging systems play a critical role in many industries. Thermal cameras rely on many of the same motorized components as standard cameras: they require focusing, zooming, aperture adjustments, and quick-moving shutters. Inside these advanced optics systems, micro brush DC motors from FAULHABER help cameras capture precise images and temperature readings in a fraction of a second.

Injection Molding: 9 tips for designing multipart assemblies
Finding creative solutions to multipart assemblies can be tricky, but fortunately there are many different ways to approach product designs that involve multiple components. To keep things cost effective and efficient, simplify your design, don't make what you can buy off the shelf, explore all of your manufacturing options, and understand the rules of each part of the process. But like most design challenges, it's not as easy as it sounds. Great info from Protolabs.

Top Tech Tip: Innovative way to take up tolerances!
Smalley Linear Springs are a continuous wave formed (marcelled) wire length produced from spring tempered materials. They act as a load-bearing device, having approximately the same load/deflection characteristics as a wave spring. Linear Springs are now available as a standard part in carbon and stainless steel, with over 200 sizes.

SureStep stepper motor linear actuators
AutomationDirect has added stepper motor linear actuators to its SureStep line of stepper motion control products. These linear actuators are NEMA 17 or 23 frame stepper motors with a stainless steel lead-screw extension of the rotor. In conjunction with the provided screw nut, these units translate motor torque into linear thrust. They can provide up to 193 lb of thrust, or speeds up to 18 in./sec. Eight standard leads (travel per rev) are offered, with screw lengths of 6, 9, or 12 in. They start at under 100 bucks.

Image - Clipped washers key when space is limited
Clipped washers key when space is limited
Design engineers who have limited space and need to control axial motion within their applications can turn to clipped washers from Boker's. Clipped washers have a flat edge on either the outside diameter (OD), inside diameter (ID), or both. This flat edge helps prevent the washer from rotating in applications, especially when space is limited and component performance is critical. Many applications require clipped washers, and they are used across many industries including automotive, marine, aerospace, and medical.

Porsche still betting on combustion engine for future
Some major automakers have committed to producing only all-electric vehicles (EVs) in the future, but Porsche isn't one of them. Sure, it already has successful EVs like the Taycan, but Porsche, through a pilot project with Siemens Energy, is developing synthetic climate-neutral fuels (eFuels) to try and keep combustion engines humming.

How a Polyclutch slip clutch works
Dynatect's Polyclutch slip clutches have a long operating life of over 20 million cycles and smooth, reliable breakaway. This video shows how a Polyclutch mechanical slip clutch works -- and what's inside. Slip clutches can be used for increasing machine speeds; applying constant tension on paper, film, wire, threads, etc.; indexing a conveyor, table, or any mechanism; holding in position a lid, cover, screen, door, window, etc.; controlling torque for bottle capping, automatic screw assembly, closing valves, etc.; soft starts; cushioned stops; and many other applications.
