RoyAlloy is a new stainless mold-base steel, developed by Edro Specialty Steels, to overcome shortcomings associated with prehardened 420F (1.2085) stainless holder steels: a lack of toughness, unpredictable stability, inconsistent machinability and poor weldability. Edro says thermal treatments give the material improved dimensional stability after machining without the need for stress relieving. RoyAlloy is a 400 series martensitic stainless designed specifically for plastic and rubber tooling. It's available from stock in flat sizes up to 12 inches thick and rounds up to 12 inches in diameter. For more information, go to http://rbi.ims.ca/4921-513.
The history of automation begins in 1790 and roars through the 20th Century with stunning advances. One of the highlights was the Ford River Rouge Plant -- iron ore went into one end of the plant and a finished Model T came out the other end.
Does it sound like magic? It's not. You can 3D-print with wood filaments right now, using a choice of colors and filament widths. Objects made from these materials range from things resembling plastic or lumber to stunningly beautiful art pieces that look just like the real thing.
Using green energy lets engineers create environmentally friendly power systems and indirectly helps to reduce greenhouse gases. The costs related in creating effective power-supply systems can also significantly become low with the use of renewable energy.
