These screens for medical applications, hydraulic-valve screens, fuel filters, laser-light filters, extruding screens, and particle separation and sizing, are are made with photoetching. This approach means that the openings don't shift or change as the screens work. They also lack the burrs that are associated with stamped screens. They can be made with straight or tapered holes, and hole sizes are as small as 0.003 inch. They are usually stainless steel, but can be other materials. Many sizes and custom shapes are available, but the standard screens have 60 or 90 degree patterns with a maximum guaranteed perforated area of 18 3 21 inches.
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.
