Hydraulic accumulators in dual clutch transmissions get plastic pistons thanks to Freudenberg
Hydraulic accumulators allow manufacturers to install smaller hydraulic systems to actuate transmission gears. But their installation is complicated by because the steel piston in the accumulator requires an elaborate sealing package. Freudenberg Sealing Technologies has developed a new plastic piston that relies on single-part sealing technology -- eliminating three parts in the sealing package.

Motors for model train meet demanding requirements
Building an N-gauge (1:160) model train system involves working with very small units. The 1930s-inspired BR 70 locomotive from Fleischmann is only 2.25 in. long when measured buffer to buffer. As on large locomotives, traction (and on the model, power transmission) between the wheel and the track is a crucial factor. To give the unit appropriately scaled big-train power with low vibration and noise, the folks at Fleischmann turned to customized DC motors from the FAULHABER Group.

Image - Top Technical Tips: Interlaced wave springs
Top Technical Tips: Interlaced wave springs
When heavy loads are necessary with a demand for greater travel, Smalley Interlaced Wave Springs can handle weighty loads in small places. Interlaced wave springs can replace heavy-duty coil springs or Belleville stacks. An interlaced wave spring is formed from two constituent wave springs of similar thickness, amplitude, and frequency. The two individual wave springs are combined together by interlacing them so that the spring turns of each spring abut each other for the entire length of the interlaced spring.

DuPont announces newest in-mold electronics inks
DuPont Electronics and Imaging is launching its second generation of In-Mold Electronic (IME) materials with key advancements in its electrically conductive adhesive, protection encapsulant, and crossover dielectric. IME technology enables functions such as touch controls and lighting to be directly embedded inside plastic parts by printing circuits onto plastic sheets, which are then thermoformed and injection molded. This allows product engineers to reduce weight and cost while increasing design aesthetics and functionality in everything from car dashboards to home appliances, using fewer parts and manufacturing steps.

First explosion-proof stackable multi-turn encoder
Sensata Technologies has introduced the first explosion-proof stackable multi-turn encoder, an ideal position sensing solution for oil and gas applications such as drawworks, top drives, and pipe-handling equipment where working conditions are extreme. The new encoder, BEI Sensors' model MAAX, is ATEX and IECEx certified to operate in explosive environments and features a Profibus output in a unique, stackable package. CANopen and SSI outputs are also available. The MAAX provides up to 16 bits of resolution as well as up to 16 bits of turns by mechanical counting. This workhorse product operates directly in Zone 1 environments without the need for an accompanying Intrinsic Safety barrier.

Spinning flare nuts eliminate loose fasteners in thin metal sheet applications
PEM SFN spinning flare nuts from PennEngineering become permanently captivated upon installation in thin metal sheets and, when paired with a self-clinching stud or other fixed externally threaded hardware, can eliminate all loose fasteners (including flange nuts) in attachment applications. These one-piece, flanged hex nuts additionally will spin freely in a sheet enabling quick attachment to mating hardware. Their use ultimately promotes savings in assembly time and costs.
