Foam moulding car body parts

John Jostins, designer of the Microcab, explains some of the materials used to mould the prototype of the eco-friendly car.

First, the design team use a CAD machine to produce foam moulds of the car鈥檚 body parts. Softer foams are easier to work with, but denser and harder foams produce a more durable prototype. The machined foam pieces are then sanded, sprayed and finished, before being used as a mould for the car鈥檚 composite body parts.
