April 5, 2018: TEI wins American Foundry Society (AFS) Casting of the Year Award

On April 5th 2018 TEI was awarded the American Foundry Society Casting of the Year award at the AFS Metal Casting Congress in Fort Worth, Texas.

This component was designed by Autodesk using Autodesk’s generative design software ‘Dreamcatcher’ which optimized the material geometry to given constraints and load conditions.  The resulting casting provides the ultimate performance characteristics with the minimum weight.  TEI cast and machined the part in 3 weeks using 3D printed sand technology and extensive simulation.  Casting, heat treatment and machining were all carried out on one site which minimized timing.

The swingarm is shown below after manufacture and also installed on the Lightning Electric LS-218 motorcycle.
