Design Essentials: The crucial role of material selection in machine design
When choosing materials for the structures, and especially the motion-related components on a machine or a piece of assembly equipment, the physical properties of those materials are vitally important to the overall life of the end product. This article explores some of the aspects of machine performance that a designer must consider in selecting the proper component materials for use in the end product. A chart is provided to assist in the material hardness conversions often needed when specifying components from various suppliers.

DuPont marks material firsts with work on tire pressure monitor
SmarTire Systems tapped DuPont Automotive and the high-performance characteristics of DuPont Zytel HTN PPA and Zytel HTN PPA SuperStructural resins for a lightweight and durable casing for SmarTire's new externally mounted Tire Pressure Monitoring System (TPMS) used as part of the SmartWave system for commercial trucks. The device marks DuPont's first use of laser welding to assemble dissimilar products in North America.

High-Powered DC Gearmotor Increases Torque, Reduces Cost
Globe Motors™ high-powered IM-21 Gearmotor delivers efficient motion control solutions for hospital beds, powered awnings, turret drives, mobility conversions, and more.

The IM-21 is available in a wide range of standard windings and stack lengths. Optional encoders, brakes, connectors, and various output shaft configurations allow a variety of customer specified combinations without the cost normally associated with custom designs. Visit Globe Motors.

Why we use … planetary gearmotors
The TUG robotic indoor transport system pioneered by Aethon Inc. is a uniquely automated courier system making the rounds in an increasing number of hospitals nationwide. The enabling technology for the robotic courier is both customized and complex, integrating microprocessors, touchscreens, infrared and ultrasonic sensors, and controllers. Direct-driving each of the robot's two wheels, PITTMAN Series 9000 brush-commutated DC gearmotors have delivered the reliability and control prescribed by the design team.

Biomedical shape-memory polymers developed
Researchers at the Georgia Institute of Technology are developing unique polymers that change shape upon heating, possibly to open blocked arteries, probe neurons in the brain, and engineer a tougher spine. These so-called shape-memory polymers can be temporarily stretched or compressed into forms several times larger or smaller than their final shape. Then heat, light, or the local chemical environment triggers a transformation into their permanent shape.

Wheels: How green is my luxury ride?
What can you do with 5 1/2 years' worth of 12-oz plastic PET drink bottles used by a single person? You can up-cycle them into the smart materials used in one of Lincoln's new MKT premium utility concept vehicles, of course. Why not replace the metal in a number of new part applications with, say, Xenoy iQ resin from SABIC Innovative Plastics for front and rear bumper energy absorbers, the center console, and liftgate inner structure? And SABIC's Valox iQ resin? Why not use that for the engine cover, connectors, power distribution boards, and the composite hood?
