For more than 60 years, engineers specifying seals and customers
using them have accepted the arbitrary rule that the maximum amount
O-rings will swell in most applications is a 25% change in volume.
But today, given the sophisticated test and analysis tools available,
experts began to question why engineers still relied on a general rule
of thumb. Simrit
conducted extensive testing to establish volume-swell relationships
between common seal materials and industrial fluids. Chemists tested VMQ
(silicone), CR (chloroprene), NBR (nitrile), FVMQ (fluorosilicone), FKM
(fluorocarbon), and EPDM (ethylene-propylene) in various fluids,
including high-aromatic gasoline, jet-turbine lubricant, phosphate-ester
hydraulic fluid, and standard reference test oils. In total, 114
different experiments indicated there is a mathematical relationship
that can predict the actual swell of O-rings installed in glands.

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.

Smaller, quieter, and more economical cooling systems for household
air conditioning and refrigeration could come of new discoveries by
researchers at the National Institute of Standards and Technology
working with scientists from the Beijing
University of Technology. They have developed a new alloy — a mix
of manganese, iron, phosphorous, and germanium — that is the first
near-room-temperature magnetocaloric material. Magnetocalorics heat up
when exposed to a magnetic field. If left to cool by radiating away the
heat and the magnetic field is removed, their temperature drops again,
this time dramatically. Such materials have long been used by industry
and science, sometimes to get temperatures down to near absolute zero,
but technical and environmental problems have kept them from being
employed in households.

Turcon MF5 and MF6 are specifically designed for use in demanding
environments, such as in the food and beverage industries. Manufactured
from high-purity PTFE grades and additives, the materials’ high-gloss
and low-porosity smooth finish reduces particle shedding and the risk of
contamination buildup.
The Turcon MF materials operate at –328 to 500°F; have low long-term
compression set, good friction, and sliding properties, high wear
resistance, minimal creep and permeation; and are compatable with most
chemicals, including organic and inorganic oxides, acids, alkalis,
amines, esters, and steam.

The abrasion-resistant Graphlon GM 860 is a tough
polymer/graphite-based material used to manufacture pump bushings and
critical wear parts. Developed specifically for sump pumps and
riverwater service pumps, it also handles the limited run-dry
requirement of these applications. The bronzes and plastics
traditionally used in pumps are prone to damage from highly abrasive
suspensions and do not handle run-dry situations well.

The Moldmender Micro Welder repairs plastic injection,
rubber-processing, and die-casting molds, as well as dies made of steel.
Typical applications are parting lines, corners/ edges, pin
holes/scratches, and machining errors. Repairs are made by producing
interlinking spot welds to totally bond metallic ribbon, wire, paste or
powder to the desired area of the workpiece. Surface finishing is done
by EDM’ing, grinding, machining, plating, or polishing.

Energy Efficiency Web Conference & Expo –
May 14
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:
- 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
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
materials.

Why Product Designers Are Switching to CoCreate Modeling
1pm EST – 1:45pm EST
Tuesday
May 12, 2009
Not satisfied with your 3D CAD system?
As a product designer or CAD manager, you must be flexible, spontaneous,
creative, and take a team design approach to creating great products.
You need sophisticated and intuitive software to create well-engineered
and attractive designs.
If you're not thrilled with every aspect of your CAD system, it may be
time to consider the benefits of switching to CoCreate Modeling - the
world's #1 explicit 3D CAD system.
To find out why engineers are switching to explicit modeling, join us
for this live webinar.

Understanding Key Power Transmission Technologies:
Comparing Belt, Chain & Gear Drives for OEM Projects
Sponsored by Rexnord
DATE: May 28th, 2009
TIME: 2:00pm ET/11am PT
OEM design teams are under pressure to juggle technologies with
specifications with the outcome always being a great new or improved
product. Many of these projects have Power Transmission components at
their core and the wrong technology can really hurt the end product.
Dennis Missun and Nick Derus from Rexnord have gathered
information about the critical issues that need to be considered when
deciding between belt, chain and gear drive technologies for
applications requiring 5 lbs – 100 lbs of force.
The course will cover
- Torque Density: comparing key rating systems AGMA & ISO
- Application considerations: impact of thermals, friction and
vibration
- Basics of sizing & selection: information to right-size
components
- Other Project/End Customer Considerations
- Live question/answer session with presenters

Minnesota Rubber and Plastics was identified as a supplier for a
Vertebral Technologies, Inc. (VTI), Minnetonka, Minn., product that won
the 2009 Medical Design Excellence Award. The award recognizes
engineering, material, and functional advances in the design of medical
products and will be presented at Medical Design & Manufacturing (MD&M)
East Conference and Exposition, June 9-11, 2009, in New York.
Minnesota Rubber and Plastics worked with VTI during development of the
Interfuse interbody fusion device, an implantable spinal device that is
less surgically invasive and lets surgeons optimize the area available
for fusion. Minnesota Rubber & Plastics designed the tooling and
injection molds the device from PEEK-OPTIMA, a biocompatible
polymer.
