Acetal isn't just for injection molding anymore. At the recent National Plastics Exposition in Chicago, DuPont Engineering Polymers (http://plastics.dupont.com) introduced Delrin® acetal sheet suitable for thermoforming. Sold under the Delrin Forming Solutions name, these new products combine acetal's superior chemical resistance and lubricity with thermoforming's manufacturing edge when production volumes don't justify injection molding. Initial applications include housings and trays for use in medical, dental, and biochemical research settings.
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.
