tin are loaded at a very high level (60 and 25 percent respectively) in
polyamide 6. The tin acts like a solder connecting the copper fibers.
conductivity of the compound is 1,000 times better than the next most
conductive plastic compound available (plastic loaded with steel fibers)," says
Thilo Stier, innovation manager for A. Schulman.
production part is a light that can be used for automotive or other end-market
production process is novel.
ABS plate and the PMMA (acrylic) reflector are injection molded in a
three-component process. The electrical resistor, diodes, LED and contact pins
for the plug are inserted and connected with the new conductive compound, which
is called Schulatec
TinCo 50. The ABS-coated reflector is then mounted to ensure watertight
the material can be used for housings and lighting applications. The new
technology permits new design opportunities while also reducing costs through
integration of structural and electrical functions into one part.
electrical conductivity of the compound is in the range of 5 x 105
S/m. The conductivity of copper alone is 5.69 x 107 S/m.
the technology began with Siemens in 1998 and was later supported by IKV Aachen, a German research
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
