Gas assist was coupled with coinjection for this Kubota sub-compact utility tractor to reduce resin content and minimize cost. Kubota and Bemis Contract Group of Lenoir, NC, partnered on the redesign to eliminate a paint requirement, simplify assembly, consolidate parts and improve the product's versatility and appearance. One of the solutions was molded-in color, said to be the first in this industry category. The coinjection tool provides the hood with integral mounting features that ease assembly, and improve driver visibility. Coinjection also allows use of reprocessed core materials. Gas assist was used for the structural hand rails that were consolidated with thin wall control covers. The materials used for the project were thermoplastic olefin (TPO), glass-filled (15 percent) polypropylene and an alloy of polycarbonate and PBT.
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.
