Shiloh: Lightweighting without Compromise
Lightweighting is an auto industry staple these days, and there are “significant” opportunities for further gains, says Shiloh Industries CEO Ramzi Hermiz.
Lightweighting is an auto industry staple these days, and there are “significant” opportunities for further gains, says Ramzi Hermiz, president and CEO of Shiloh Industries Inc.
Shiloh is agnostic about materials, preferring to focus on the best solution rather than “selling” one technology over another. The aim is to reduce both weight and cost.
One recent example: a cast aluminum rear solid axle housing, which weighs half as much as a traditional cast iron unit. The component is easier to machine. And Hermiz notes that its lighter weight means lower per-piece shipping costs, because trucks can carry twice the number of components per load.
Generally, when OEMs produce aluminum engine blocks (aluminum rather than cast iron because cast iron weighs like cast iron), they insert sleeves into the piston bores—cast iron sleeves.
The engineers at Zenos Cars have combined recycled carbon fiber, drinking straws and aluminum to create a chassis for a low-volume sports car.
Automotive manufacturers are meeting CAFE fuel-efficiency standards through lightweighting, which requires simulation software for design engineers.
