With the holiday season in full swing, our guess is that November's
Smartest Design Engineer Corey Ruchs (corey872) from BNSF Railway
will be using his $250 Amazon gift card to make short work of his
shopping list. Corey registered for the game November 1, so there is
hope for those who haven't tried WSDE yet. Even bettter, in 2011 there
will be five WSDE winners each month in addition to an overall yearly
winner. In 2011 there will be more new questions, too, including a new
Materials category and questions based on content in Machine Design and
on our website.
The 2011 version begins January 1 so study up now with some recent and

Bigger role for rapid prototyping in
In the current economy, rapid-prototyping techniques are gaining new
respect as a way of fabricating parts that do double duty: serving as
functional prototypes for trying out concepts and, in some cases, being
tough enough to work as production parts. Moreover, OEMs increasingly
find that additive-prototyping methods such as stereolithography (SLA)
make it possible to devise limited-run parts that would have been
uneconomical to produce otherwise.

The fundamentals of annular snap-fit
Snap-fit joints are the most widely used way of joining and
assembling plastics. They are classified according to their spring
element and by separability of the joint: Will it be detachable,
difficult to disassemble, or permanent? The most common snap fit is the
cantilever. But the perhaps least understood type is the annular snap

Non-sagging light-cure adhesive
Loctite 3979 single-component, light-cure adhesive is a translucent,
non-sagging gel that fills moderate gaps without migration, cures
tack-free in seconds in UV/visible light, and fluoresces red for
inspection. It adheres up to 3,500 psi on plastic, metal, and glass
substrates and cures to depths greater than 0.25 in.
It is biocompatible to ISO-10993 and withstands temperatures from -65 to
300°F. It comes in 25-mL syringes and 300-mL cartridges for
automatic or manual dispensing.

Electronic swinghandle latch
The H3-EM electronic locking swinghandle latch is
microprocessor-controlled and gear motor-driven. It uses less than 200
mA of operating current at the moment of actuation only. It integrates
sensors and outputs for industry-standard rack control and monitoring. A
simple retrofit permits addressable remote access control over the web.
It can generate an activity log.
The glass-filled nylon H3-EM fits industry-standard panels and both left
and right doors. The assembly can be customized to meet color, logo, and
Ultrasonic welding equipment
New HiQ ultrasonic welding machines include Dialog, Vario, and Logic
units. Dialog has four weld forces permitting force profiling, extended
memory for 300,000 welds, and weld-process graphics with EasySelect and
expert modes. A quick-change system permits ultrasonic stack mounting
The Vario pneumatic drive unit has proportional valve technology and
digital generators with various strokes, cylinder diameters,
frequencies, and power outputs up to 6,000 W. Graphics visualize joining
processes and record quality. Standard equipment includes multiple USB
high speed interfaces, printer, and Ethernet connections.
The Logic units include a travel measuring system, proportional valve
technology, password protection, volume counter, and five operating
modes: time, power, energy, depth RPN and absolute distance. The unit
has a 5.7-in. touch screen.

Precision Plastic Parts:
Developing Components to Meet Project Requirements
Sponsored by: Accumold
Date: December 14th, 2010
Time: 2:00pm ET
OEMs are pushing for the greatest amount of functionality and quality in
the smallest product space possible. These requirements force
engineering teams to work through difficult challenges, many of which
will require precision or micro molded plastic parts. The right
solution doesn’t appear magically. Designers test concepts,
investigate materials, prototype component options and validate
To help designers move through this process, Accumold’s engineers are
presenting a technical webcast on the key issues and caveats OEMs should
understand in working either internally or with outside vendors on a
precision molded solution.

Fabrico debuts CNC die-cutting
Kennesaw, Ga., is featuring a video on its website that details its CNC
die-cutting and wide-web-laminating capabilities for flexible materials.
The CNC die-cutting and wide-web-laminating system efficiently cuts
flexible materials with close tolerance cutting and optimal layout for
higher output and less scrap. It maintains accuracy with a speed of 966
mm/s over long runs.
Fabrico’s CNC die-cutters accommodate materials -- including foam,
rubbers, tape, and paper -- up to 1,400 mm wide and 1 in. thick for 324
in.2 of die cutting space with a maximum part size of 25 in.
square. In-line stamping and laminating increases lead-time and
throughput. Mix-and-match of multiple substrates is also possible.
The company's capabilities are shown in a web video.

Matheson opens online welding-products
Matheson, Basking Ridge, N.J., announced the launch
of an online store for specialty gas equipment, welding equipment,
welding supplies, associated accessories, safety products, and power and
construction tools at www.MATHESONDirect.com. The company previously
offered online ordering to its customers with existing “house
accounts," but the new site enables credit card transactions for old and
new customers. The store carries welding products, power tools, and
construction tools from over 120 well-known manufacturers such as
Lincoln, Miller, Hitachi, Milwaukee, Skil, Bosch, Makita, and Dremel as
well as MATHESONSelect.
Customers can search and sort by price, category, manufacturer, and
product SKU number. An interactive Regulator Selection Tool lets
customers choose options using pull-down menus. Customers can also
review specifications before purchase.
