Gas-assist molding was used to reduce warpage in this rocker molding on the current Honda Odyssey van. Gas assist relieves isolated stresses and provides even packing through the length of the part. Gas assist also eliminated sink marks to produce a Class A surface. A perfect color match is achieved through use of a thermoplastic olefin paint film, which provides an environmental benefit as well. It reduces emissions of volatile organic compounds and is recyclable. The part was designed and molded by Green Tokai Co. of Brookville, OH. The company also says that side-impact testing of the film-sheathed side sill outperforms conventional paint. The part is molded in a two-cavity family tool.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
