Sandvik has developed two new precoated metal strip steels that are
intended to boost productivity and reduce environmental constraints associated
with plating and coating.
"Our diverse stainless steels can
be coated with several layers of metals like nickel, tin, silver or similar,
which increases product performance through high surface conductivity,
corrosion protection and wear resistance," says Jeremy Gaspard, marketing
specialist – Americas for Sandvik, referring to a new grade for electronic
applications called Santronic.
By combining an advanced vacuum process with nanotechnology, Sandvik
says it can produce strip steel with consistent coating layers as thin as 20
Another product line, called Sandvik Decorex, features a range of
colored stainless steels that were developed for decorative parts for
appliances, consumer electronics, packaging and automotive.
Sandvik says that Decorex strip can be cold formed and bent to close
radii without affecting the color quality due to excellent adhesion between the
base material and the coating.
The precoated strips are more expensive than noncoated stainless steels,
but Sandvik would not provide any examples of pricing.
"Generally, our clients have a total savings of 15 to 30 percent over
traditional processes," says Gaspard. "This is based on their current supply chain
and manufacturing process."
Decorex is generally supplied on 304 stainless steel substrate for
formability purposes. First the customer selects a thickness, texture and
width. Then Sandvik produces the customer color choice using its technology
coating process, which is similar to but more advanced then commonly used PVD
(physical vapor deposition) processes.
Santronic is generally supplied on 301 SS substrate for tensile strength
and fatigue resistance purposes. The buying process also starts with a customer
selecting a thickness and width. Then Sandvik produces the coatings on one or
two sides of the base material using its technology coating process.
Prices depend on the color, the texture, the thickness, the width and
The energy consumed to produce one square meter of Santronic or Decorex
is 1.264 kWh, says Sandvik. Other processes consume far more energy, according to Sandvik.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
