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.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
