|The latest information on engineering materials
|| March 3, 2009
It's March, but winter is still gripping much of the country and the
economic picture is as bleak as it's been for months. But even when the
world seems stuck in a rut, engineers keep finding new ways to meet
In this month's newsletter we'll look at polymers for
cabling, magnesium molding, and thermoplastic elasotmers. Scroll down for new products, news from MD, and industry news.
And please let us know how you're weathering both winter and economic
storms. You can contact us by email, comment on any article on our website, or post

When you think of polytetrafluoroethylene (PTFE), the nonstick
coating on your pots and pans might be the first thing that comes to
mind. Some of the same properties that let food release from cooking
surfaces have made PTFE attractive to engineers for applications from
insulation to sliding surfaces since its discovery in 1938.
These same characteristics let PTFE and its expanded derivatives (ePTFE)
work well in cables for today’s demanding, high-flex, low-downtime
applications. The materials can give cables long flex-life, extra
strength, better signal transmission, and clean-room performance.

FREE FRICTION CD FROM GENERAL
the life of metal components with a FREE CD-ROM from General Magnaplate.
The easy-to-use CD assists design engineers in selecting permanent
coatings that prevent wear, friction, corrosion, sticking, galling, and
chemical attack on ferrous and nonferrous metals. The CD resource
compares the static and kinetic coefficient of friction (COF) of
numerous metals with 20 Magnaplate-applied 'synergistic' coatings.
General Magnaplate's surface enhancements become an integral part of the
metal providing permanent, superior performance.
Magnesium injection molding (MAG) shapes parts out of magnesium
alloy in a semifluid state, without the need of binders, resins, or
sintering. This gives the relatively new technique an environmentally
friendly tag. MAG is a socalled “thixomolding” process — the name
comes from the word “thixotropy,” the property of certain fluids to
exhibit changes in viscosity depending on sheer stresses. MAG produces
net or near-net parts.

requires the right tools to get the job done correctly. Danaher Motion
has created a web page with descriptions and access to motor
sizing/selection software, on-line servo technology database, an
engineering toolbar for various calculations and more. The site even

TPEs, a varied class of compounds that are easier and greener to
process than thermosets, are gaining acceptance in industries including
automotive and medical.
Thermoplastic elastomers (TPEs) are showing up in more and more places
these days. The array of polymers that fall under the TPE umbrella, not
to mention the color, texture, and property options they offer
designers, can be truly bewildering. But sorting out the TPE universe
can help a designer cut part count, shorten process time, and improve

The BC40 Tru Temp finishing system forms a corrosion-resistant,
nondimensional, black magnetite finish that meets MIL-C-13924C, Class-1
requirements on iron or nonstainless-steel parts. The process uses
two-stage oxidation at 200°F. Process turnaround time is 25 min, with
throughputs of up to 2,000 lb/shift. The finishing system's seven 16 ×
24 × 24-in. tanks have a total footprint of 3 × 15 ft. The low
temperature prevents boilover, and process chemicals are not EPA
Lexan Thermoclear clear, multiwall sheets have a nine-wall, X-shaped
cross section that forms multiple insulating air pockets between indoor
and outdoor environments. The trusslike structure also adds stiffness,
strength, and impact resistance. The sheets’ overall heat-transfer
coefficient is 1.187 to 0.985 W/m2-K. A proprietary coating on each
surface provides UV protection and preserves optical quality. The
material comes in 35, 40, 45, and 50-mm thicknesses.
Dual-Cure 9481 one-part, solvent-free, acrylated urethane conformal
coating sets in 3 sec and reaches full cure in about 5 min under visible
or UV light. Shaded regions of the part reach full cure in two to three
days in ambient moisture. The coating fluoresces blue under blacklight
The uncured material has low surface energy and 125-cP viscosity. It can
be sprayed on to a final thickness of 0.001 to 0.003 in. It has a
dielectric constant of 3.25 and a dissipation factor of 0.01 at 1 MHz.
Its dielectric strength is 75 kV/mm, and its surface resistivity is 2.46
Energy Efficiency Web Conference & Expo –
Do you know you can get in-depth education on energy-efficiency and all
the benefits of an in-person trade show without ever leaving your desk
or spending a dime?
The intelligent use of energy is making headlines. Product designers and
manufacturers are striving to deliver products that consume less power,
extend battery life, generate less heat, or work from alternative energy
sources. Our Energy Efficiency Web Conference and Expo will
educate design engineers, product developers, and managers on how to
make the best use of energy-efficient product innovations and devices,
and on how to arrange them in systems to lower power consumption and
stay "green." This special one-day event will include sessions
on such areas as:
Make plans now to attend the Energy Efficiency Web Conference and Expo. The
event offers a full day of live webinars and interactive booths, along
with a Resource Center where visitors can download or link to additional
- Power-efficient drive techniques for lighting
- ROI for high-efficiency capital equipment
- Energy monitoring and energy standards
- Designing for SEMI S23 and the Energy Act of 2007
- Working with alternative power and battery technology

Collaboration is essential to successful product development in
today’s difficult economy. However, facilitating and managing the
process is growing increasingly difficult. Design teams must
participate from all parts of the world, develop products that are more
complex than ever before, and deal with product-update cycles that move
faster and faster.
Do you have the right CAD collaboration platform?
Companies of all sizes face Product Data Management and Product
Lifecycle Management challenges. Fortunately, quick-to-deploy solutions
can help companies overcome these challenges. In this Webinar, we’ll
explore how design teams in small and medium-size companies can use
these solutions to work concurrently, find the right files, share data
and enable social product development.
- Do you use network folders or an FTP site to manage CAD
- Have you experienced trouble locating the latest versions of CAD
- Are you looking for an easy way to collaborate internally?

The Fundamentals of CANopen for Industrial Machine Control
Sponsored by Maxon Precision Motors
DATE: March 12th, 2009
TIME: 2:00pm ET/11am PT
CANopen is an industrial networking system used in millions of
applications worldwide. It is based on Controller Area Network (CAN)
technology, a proven serial bus that links multiple devices, allowing
them to work together.
Optimized for reliability and real-time control, CAN/CANopen is
especially well suited for motion systems consisting of actuators,
sensors, controllers, and analog and digital I/O. It also offers a
competitive edge. Unlike other serial-bus systems, CANopen maintains a
certain level of manufacturer independence through standard device
profiles with layered flexibility.
In this overview of the CANopen specification, we will give designers a
fundamental understanding of the platform, advantages and disadvantages,
and where the standard is headed. We’ll also take a focused look at
device profiles, including an actual multi-networked application, and
explore the various communication layers and how they can be optimized
for industrial control applications.

DSM Desotech's antitrust case moves
Photochemical resin supplier DSM Desotech's federal and state
antitrust case against 3D Systems has been approved by a U.S. District
Court. Judge Joan H. Lefkow ruled the majority of Desotech’s claims
could proceed, including claims for attempted monopolization,
unreasonable restraint of trade, deceptive trade practices, and tortious
interference with prospective business relations. 3D Systems did not
move to dismiss Desotech’s patent infringement count.
