Rogan Liquid Silicone Rubber Molding Capabilities
Rogan Corporation, a full turnkey contract manufacturer of plastic components and assemblies, includes producing injection molded Liquid Silicone Rubber (LSR) components as a rapidly growing segment of the business. The company is one of a few select manufacturers that also offer Bondable Liquid Silicone Rubber (Bondable LSR) overmolding that is injection molded directly to plastic or metal parts, creating a single integrated component. Utilizing LSR's heat/chemical/shock/vibration resistance and sound dampening, design opportunities include integral seals and gaskets for waterproofing complex geometries and electronic interconnects, integral membranes, diaphragms, valves, and switch covers. (Picture has .008" thick fins bonded to plastic tube.)

Our state-of-the-art Class 100,000 clean room enables Rogan to meet the increasing demand for LSR molding and assembly for the medical device market.

Newspaper techs get lessons in troubleshooting, restarting presses

The Courier-Journal, which prints three editions each night and is the single largest daily newspaper in Kentucky, uses a new, state-of-the-art KBA press. Instead of a mechanical main shaft with couplings, drives, and cams, Rexroth's SYNAX system uses synchronized electric drives and motors to implement the press functionality. Rexroth's Syntop software is used to interface with the electronic control system.

Army tries thermoelectrics to reclaim wasted tank, UAV energy
Automakers General Motors, Volkswagen, and BMW are developing thermoelectric generators that recover waste heat from commercial car and SUV combustion engines and reuse it as electricity. Now the U.S. military wants in on the technology, too.

Touch-sensitive plastic skin heals itself
A team of Stanford chemists and engineers has created the first synthetic material that is both sensitive to touch and capable of healing itself quickly and repeatedly at room temperature. The advance could lead to smarter prosthetics or more resilient personal electronics that repair themselves.

Jounce bumper gets the all-in-one treatment from DuPont

DuPont Performance Polymers featured an innovative automotive jounce bumper component at the FAKUMA 2012 show Oct. 16-20 in Germany. The part is another feather in DuPont's cap when it comes to showing how design, materials, and processing (and a little technical help from your friends) can deliver added performance and lower cost.

GE Energy kit makes board design super simple

GE Energy's new Digital Power Insight kit is a plug-and-play tool set that makes circuit board design and testing fast and painless. It enables power designers in telecom, datacom, industrial, and medical segments to experiment and design on the fly by automating all the time-consuming calculations for board testing. Volts in, volts out, amps out, and all other pertinent data never looked so good for under $100.

Engineer's Toolbox:
Choosing the right motor technology for your miniature pump

While there are parameters of design that can be changed within a mini pump, the critical item in pump performance is the motor selected, since it generates the flow, pressure, or vacuum. Learn about proper motor selection, which leads to optimum pump performance and a more efficient end product.

Image - Self-regulating heating cables
Self-regulating heating cables
Heat Trace 2700 Series Self-Regulating Heating Cables from Heat Trace Products provide freeze protection and process temperature maintenance for fluid transport and storage systems. They feature a multilayer construction and supply a specified amount of heat at any point along their length in direct response to local temperature variations. Capable of maintaining temps up to 150 degrees F, with intermittent exposure to 185 degrees F, these cables are offered in output wattages of 3-, 5-, 8-, and 10-W/ft at 50 degrees F. They will not overheat or burn out when overlapped, and they can be cut to length and terminated in the field.

Image - Could this be the world's most effective wedge-locking washer?
Could this be the world's most effective wedge-locking washer?
X-series washers combine Nord-Lock's unrivaled wedge-effect solution (to prevent spontaneous loosening) with an exceptional spring effect (to compensate for loss of preload due to slackening). When used in pairs, each washer duo has cams on one side and radial teeth on the opposite side to secure the bolted joint with tension instead of friction. Quick and easy to install and remove with standard tools, this is a great solution for handling vibration and dynamic loads, painted or powder-coated surfaces, soft metals, and composites and polymers.

Image - Linear stages for quick and easy system integration
Linear stages for quick and easy system integration
Integrating a linear motor into your system is a snap with SCR and SLP linear stages. Both are built around Nippon Pulse's Linear Shaft Motor, the first motor designed for the ultra-high-precision market. Both the SCR and SLP series stages come with integrated bearings and encoders to reduce cost and simplify integration into your application. The SCR nanopositioning stage offers the speed of servo stages and the accuracy and precision of piezo stages. Built with cross-roller bearings, the SCR nanopositioning stage gives you extremely straight and flat motion. The SLP Acculine series is ideal for industrial applications requiring both precision and high force, and offers between 17 N and 970 N of linear force and extremely high resolution.

Taking the edge off a pipe bomb, literally
The Department of Homeland Security Science and Technology Directorate's new low-cost device for dismantling dangerous pipe bombs may look like a tinkerer's project, but that's no accident. The Semi Autonomous Pipe Bomb End-cap Remover (SAPBER) is unassuming in appearance, but sophisticated enough to preserve the forensic evidence needed to track down the perpetrator.

Computer-driven airplane optimization stretches its wings

A modified version of one of the U.S.'s most popular passenger jets, proposed by a computer program, could cut the plane's jet fuel burn for all its flights by an average of 8.8%. The software, developed by a University of Michigan professor, combines airplane structure and aerodynamics into a single optimization program that zeroes in on the most fuel-efficient and cost-effective airplane designs.

The True Cost of Bearing Lubrication
Bearing lubrication failures can affect both your budget and the environment.

This video aims to lift the veil on the hidden and unrealized costs of lubricating and re-lubricating a bearing. Learn how improper bearing lubrication can increase expenses exponentially and discover how dry-running, self-lubricating bearings can make machines operate better and reduce your budget.

Galil's DMC-2143 motion controller used in Force Dynamics' 401CR simulator
For those dreaming of what it actually feels like to be a jet pilot or Indy race car driver, look no further than Force-Dynamics' Motion Simulator Systems (MSS). The experience is so realistic that you can actually feel the G-forces against your body during acceleration and bounce to every nook and bump on the road. The Galil DMC-2133 3-axis Ethernet motion controller is used in Force Dynamics' 301 3-axis platform, which provides +/- 30 degrees of roll, pitch, and heave motion. The DMC-2143 4-axis controller is used in the 401CR 4-axis model, which adds 360 degrees of unlimited yaw motion and a whole lot more fun.
