Guide to overmolding best practices
Overmolding is a great injection molded feature you can utilize in your design to capture color contrasts, add flexibility or eliminate assembly. Take advantage of this feature by learning how to design your part for overmolding.
You'll learn:
  • How to set up your design for complex overmolding
  • Material evaluation and best practices for proper adhesion
  • Feature specifications to consider for good overmolds

These lithium-ion batteries can't catch fire because they harden on impact
Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. Inspired by the weird behavior of some liquids that solidify on impact, researchers have developed a practical and inexpensive way to help prevent these fires.

Image - Nexen expands precision rotary indexer line
Nexen expands precision rotary indexer line
The Motor Ready Sealed (MRS) precision rotary indexer maintains the benefits of Nexen's existing patented precision roller pinion drive design -- zero backlash, high precision, high torque, and high acceleration -- while delivering significant new benefits. A high roller pinion-to-gear ratio allows users to direct drive the system with the addition of a servo motor, eliminating the cost of a reducer. For high-load applications, the customer can drive the system with a reducer/motor combination. Additionally, the gear-to-pinion reaction loads are fully supported, so the servo motor shaft is not subjected to radial loading, which eliminates the need for costly high output-capacity reducers in high-load applications. All of these features reduce engineering and installation time.

Engineer's Toolbox: How Design for Assembly helps additive manufacturing succeed
Product development today is still a type of puzzle board, a maze of individual parts and players that need to fit together. Additive manufacturing can begin to really change that, but it will only do so if we know how to drive all design facets and puzzle pieces toward simplicity -- and can see the purpose of the product as a whole, executed in as few parts, operations, and suppliers as possible. Nicholas Dewhurst, Executive VP, Boothroyd Dewhurst, takes a deep dive into the (sometimes seemingly complex) process of part simplification using the latest technologies. Great information here!

Universal Robots' 25,000th cobot sold is gold edition awarded to customer at IMTS
To celebrate the sale of 25,000 cobots worldwide, Universal Robots gave away its first and only Gold Edition cobot to the lucky customer who ordered the 25,000th cobot. The milestone was announced Sept. 10 in Chicago at IMTS, the nation's largest manufacturing trade show. Cobots are now the fastest growing segment of industrial automation, expected to jump tenfold to 34 percent of all industrial robot sales by 2025.

Image - How colorants affect plastic characteristics
How colorants affect plastic characteristics
If you're starting a custom plastic injection molding project, you'll want to select a material with the properties most suitable for the function of your parts. One aspect of polymer characteristics that doesn't always get the consideration it deserves is the addition of colorant. Believe it or not, there is a whole scientific body of knowledge about the ways in which adding color to plastic can affect the behavioral properties of the plastic. This short article by Denny Scher of ICO Mold takes a high-level look at some of the different, and surprising, ways colorants can have an effect on plastics.

Electromechanical actuators with modular design
SKF CASM-100 electromechanical actuators from SKF Motion Technologies have been uniquely engineered with a modular design, enabling tailored solutions for a wide range of industrial linear movement and positioning applications. Modules provide choices among motor types, gearboxes, ball screws or roller screws, and accessories. Standardized interfaces connect the different components. These actuators use up to 80 percent less energy than pneumatic cylinders and 50 percent less energy than hydraulic alternatives and eliminate any need for constantly running compressors, hoses, and other components.

Image - Through-beam object-detecting fork sensors
Through-beam object-detecting fork sensors
Fork sensors (slot sensors) from AutomationDirect are U- or L-shaped through-beam object-detecting sensors that have the transmitter and receiver built into the opposing "fork" arms of the sensor housing. New PS series fork sensor additions include harsh-duty U-frame sensors for food applications, L-frame or angled fork sensors for unique mounting situations, and fork sensors for liquid detection. Depending on the model, PS series fork sensors are available in visible red, infrared, and laser lighting and in sensing ranges from 5 mm to 220 mm.

160 pages of piezo linear motors, rotation stages, and multi-axis motion systems
PI's new comprehensive piezo motor solutions catalog covers a large number of linear, rotary, and multi-axis motion systems based on a variety of piezo motor types along with their appropriate controllers and drivers. Ultrasonic piezo motors, for example, are preferred for high-speed applications; inertia motors are small and cost efficient; PiezoWalk drives provide the highest forces up to 800N; and piezo-ratchet drives can replace micrometers in remote "set and forget" applications. All piezoelectric motors are self-locking, field-less, and not affected by magnetic fields, and they can be integrated easily mechanically.

Opposed-piston diesel engines are crazy efficient
Jason Fenske from Engineering Explained takes a look at the Achates Power opposed-piston engine, which is packed full of unique technology. The supercharged, turbocharged, diesel three-cylinder makes use of six pistons, two of which operate in each cylinder. Research has shown two-stroke opposed-piston engines to be wildly efficient. Three-cylinder designs are the most efficient, and it's possible to achieve brake thermal efficiencies as high as 55 percent, a massive improvement for road car engines.
