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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
