Bearings play a vital role in most every machine. They’re
especially important in packaging equipment that handles sensitive
products and must meet high standards of cleanliness and hygiene. And,
of course, every manufacturer and user demands competitive costs and
To that end, engineers are increasingly turning to plastic bearings for
packaging tasks ranging from cartoning and filling, to palletizing,
labeling, and inspection. Plastic bearings are inherently corrosion
resistant and maintenance-free, making them cost-effective replacements
for most ball bearings. They are also self-lubricating and operate
oil-free — a major advantage because lubricants can contaminate food
and attract dust and dirt, which can eventually cause bearings to

HPL (High Power Lighting)
Company introduces a high thermal performance dielectric into its
comprehensive Thermal Clad Metal Core PCB line. HPL is specifically
formulated for high power lighting LED applications with demanding
thermal performance requirements. HPL offers many benefits including:
- Very low thermal impedance 0.02°Cin2/W
- High thermal conductivity of 3.0 W/m-K
- Available on aluminum and copper metal substrates

Under normal conditions, the organs of the human body self-regulate
and heal when damaged. But when the damage is more severe, it is not
always easy in today’s rapidly paced society for patients to get
enough rest for the body to heal fully. This is certainly the case when
soft tissue such as the ligaments around joints is damaged. In these
instances, it is best to implant ligament-augmentation systems to
stabilize the joint, allowing the body to heal fully.
Some of these implants are only needed for short periods until they have
served their purpose. This leaves the problem of what to do with the
implant when it hinders full motion in the joint at a later stage. It is
almost impossible to remove soft-tissue implants, which are
traditionally made of fabrics or biotextiles. However, the development
of specialized hyperelastic polymers makes possible soft-tissue implants
which perform mechanically as required for a short period of time to
stabilize the joint. They then biodegrade naturally, eliminating the
need for surgical removal.

The Benefits of Investigating Surface Treatments|
|Too often the
coating of parts is an afterthought for design engineers. Rather than
being a part of the discussion in the early stages of design, designers
try to solve problems with coatings at the point of manufacturing - or
even after manufacturing. While each type of surface treatment provides
its own unique set of properties and benefits, each of these processes
also has limitations that should be addressed early on in the design
process to ensure optimal performance. Download this valuable white
paper to learn more.|
An engineer at Lawrence Livermore National Laboratory patented a
zinc-air fuel cell that was recently licensed to Zinc Air Inc.,
Kalispell, Mont. The cell combines atmospheric oxygen with zinc pellets
to generate electricity and recyclable zinc oxide.
Compared to lithium-ion batteries, the zinc-air fuel cell has several
advantages. Zinc is widely available. The zinc produced worldwide in 21
months would make 1 billion 10-kW-hr zinc-air cells compared to 180
years of lithium production to make an equivalent amount of lithium-ion
batteries. The zinc-air cell contains no toxic materials.

Objet DurusWhite FullCure430 polypropylene-like material works with
the Polyjet rapid-prototyping process. The process deposits
16-micron-thick layers of UV-curable polymer for vertical tolerances of
± 0.002 in. or better.
Prototypes made of DurusWhite mimic the flexibility, appearance,
strength and toughness of final, mass-produced, polypropylene parts.
The EMI/RFI Testing “Survival Kit” includes items engineers need
to test the ability of various materials to shield electromagnetic
interference (EMI) and radio-frequency interference (RFI). The Kit
includes magnetic-field and electric-field probes with cabling and probe
tips, and an EMI/RFI demo fixture. The kit also contains samples of
nickel bonded to copper-plated polyester-fabric tape with conductive
adhesive, embossed foil tape, aluminum-foil tape with conductive
adhesive, tin-plated copper-foil tape with conductive adhesive, EMI
absorber materials, EMI gasket materials, polyester-laminated
aluminum-foil tape with conductive adhesive, and die-cut
WG102 wear-grade, polyarylether ketone (PAEK)-based compound,
produces parts that cost less and are lighter than similar metal,
polyimide (PI), and polyamide-imide (PAI) parts. The polymer also has a
50% lower coefficient of friction compared to PI and PAI so it heats up
less and wears longer. WG102 retains dimensions, strength, and stiffness
up to 572°F with 25 to 75% lower wear rates.
The polymer resists chemical including service fluids and contains no
polytetrafluoroethylene (PTFE). Its melt-flow characteristcs allow
thin-walled component design and the ability to consolidate complex
parts, to reduce part costs. The polymer works with standard injection
molders without postprocessing and is recyclable.
