Description: This is a schematic image of an extrusion process being used to produce a rod that can be cut into gears. By extruding a deformable material such as metal or thermoplastic through a bridge die containing a gear-shaped hole and a square bridge it should be possible to produce a very 'thick' gearwheel. This can then be cut up into identical gearwheels of the required thickness.
