Cryogenic processing — treating parts at –300°F or colder —
benefits not only tool-and-die sets. It has quadrupled the life of
lumber mills’ log-chipper knives, let automakers’ resistance-welding
electrodes run six times longer, and improved metal guitar-string
harmonics. Audiophiles who have returned to vintage sound equipment
powered by vacuum tubes swear cryogenically processed vacuum tubes
produce discernible sound-quality improvements.

FREE FRICTION CD FROM GENERAL
MAGNAPLATE
 Increase
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.

A steel manifold, lockset refractor, all-terrain-vehicle
transmission parts, an air nozzle, and a fiber-optic connector all
garnered honors in the 2009 Powder Metallurgy Design Excellence Awards
Competition. The competition, sponsored by the Metal Powder Industries Federation (MPIF), covered
five categories: automotive engines, hardware and appliances, lawn and
garden and off-highway, hand tool and recreation, and electrical and
electronic components.

Airlines have long been removing nonessential weight from their
airplanes to save on fuel expenses or add paying passengers. So it may
be surprising that the trolleys carrying drinks, meals, and packets of
pretzels or peanuts are made the same way they have been for years —
out of aluminum.
AeroCat B.V.,
Tilburg, the Netherlands, a company that builds these trolleys, designed
a totally new catering trolley made almost entirely of injection-molded
and extruded plastic. The company partnered with Solvay
Advanced Polymers, Alpharetta, Ga., plastics processor Bemis
Manufacturing Co., Sheboygan Falls, Wis., and RFID expert Zetes Industries,
Brussels.
The new trolleys are undergoing industry trials, and it is hoped they
will earn European Aviation Safety Administration certification under a
European Technical Standard Order. Once the design is approved, AeroCat
plans to sell or lease trolleys to airlines as part of a total catering
concept.

EP30BN two-part, boron-nitride epoxy adhesive helps with thermal
management for aerospace, defense, and microelectronic assemblies. The
epoxy's medium viscosity lets it flow in bonding, sealing, and potting
applications.
It has a specific gravity of 1.1 and cures at room temperature or
elevated temperatures. The epoxy works between -60 and 300°F. Its
volume resistivity is over 10E14 ohm-cm, and it has a thermal
conductivity of 24 BTU/hr/sq. ft./°F/in.

Ethylene propylene diene monomer (EPDM) E7502, fluorocarbon (FKM)
V8605, and FKM V8T41 sealing materials are for hygienic-design
couplings. They have less than 10% volume swell in 21 common
cleaning-in-process (CIP) media.
EPDM E7502 has high chemical resistance to polar solvents, steam, hot
water, and alkaline cleaning fluids. FKM V8605 withstands high
temperatures and contact with high-fat media such as edible oils or
cosmetics. FKM V8T41 has hot-water and steam resistance up to 338°F. It
also gives high performance in contact with dry and liquid products in
the meat, poultry, dairy, pharmaceutical, and bioprocessing
industries.
All three materials comply with FDA, 21 CFR177.2600, 3-A, USP Class VI,
USP and DIN EN ISO 10993-5, and EC 1935/2004. Gaskets and O-Rings come
in ISO 2852, DIN 11864, DIN 32676, and custom sizes.

The mini BK-LC black-oxide coating line uses a dip-tank procedure to
durably coat aluminum with one heated tank and no electrolytic current.
Coating is acheived in about 30 min depending on the alloy.
The finish formed is smooth, black, tightly adherent, and 1.5 microns
thick. The process works on all cast and wrought aluminum alloys. 2000
and 7000 series alloys may need additional surface preparation.
The kit contains seven 5-gal immersion tanks, covers, an immersion
heater, and chemical products to operate for 2-6 months, depending on
workloads. The line occupies about 20 sq. ft.

The Energy Efficiency Web Conference & Expo
Engineers saw and heard great educational content at the Energy
Efficiency Web Conference and Expo. If you missed the live virtual
event, don’t despair! An archive of the full day’s agenda is now
available.
Design engineers are required to integrate energy efficiency into their
designs while maintaining lower costs, the highest reliability or both.
The editors of Machine Design understand these challenges
and have developed this conference to help engineers understand the
recently imposed energy mandates. The information presented at this
educational event will help engineers compare the different technologies
and product related to energy efficiency. Attendees will gain access to
the technical information needed to help them make the best decisions
without having to travel or take time away from current projects.
Visit the archive to:
- View informative webinars on energy efficiency
- Visit interactive booths where you can contact suppliers
- Peruse the Resource Center where you can download or link to

UPCOMING WEBCASTS
Optimizing Mechatronic Systems Using Simulation
Sponsored by The MathWorks
DATE: September 10th, 2009
TIME: 2:00pm ET/11am PT
Are you encountering integration errors in mechatronic systems late in
development during hardware prototyping?
Simulating mechatronic
systems in one environment that combines mechanical, electrical, and
control system modeling makes it easier to find performance errors early
in your development process. In addition, current simulation technology
allows integration of engineering data from different CAE tools, such as
CAD and EDA, reducing translation errors.
Attend this live webcast and learn how simulation can help you:
- Build multidomain mechatronic system models
- Predict and optimize system performance
- Understand and manage complex system interactions
- Detect design inefficiencies and integration errors during
development
- Verify and test mechatronic systems before building hardware
prototypes

Dow Chemical Co.,
Midland, Mich. opened a Film Application Development Center in Freeport,
Tex. The plant features a Hosokawa Alpine American 7–layer coextrusion
(“coex”) blown-film line in addition to three multi and two
mono-layer blown-film lines, two cast-film lines, one extrusion coating
line, and associated fabricating and testing equipment. Polymer
characterization laboratories, a sensory science laboratory featuring
taste, odor and haptics testing capabilities, and pilot plants are also
on site.
Dow customers can test out the company's resins using these capabilities
before committing to a bulk purchase, or they can develop new and
improved film structures for packaging and other applications. Company
officials say the film-development center will give customers "same-day
sample quantities of commercial grade films."

DSM Engineering
Plastics, Evansville, Ind. is increasing prices for Akulon polyamide
6 base and and high-viscosity polymers by $0.10/lb. The change affects
the polymers sold in North America and takes effect September 1, 2009.
The company attributes the increase to raw-material price escalation.
In a press release, DSM said it "continues to pursue and implement cost
savings initiatives targeted at absorbing the impact of the raw material
escalation" but that it needed to pass some price increase onto
customers to ensure its continued growth.
For more information, contact DSM Engineering Plastics.
