Abstract

The starting material in a thixotropic forming process for the manufacture of road wheels, fitted ultimately with pneumatic tyres, is an ingot (1) of rheocast metal alloy preheated to the semisolid state: the ingot is injected into a closed die (5) affording a cavity (7) in the shape of the wheel and equipped with independent thermoregulating circuits (6), routed and controlled in such a way as to maintain the wider passages (A) of the cavity at a temperature lower than that of the narrower passages (B); to ensure the die fills properly, the ingot (1) is injected at a variable and controlled velocity, correlated both to the rate at which the alloy spreads through the cavity (7) and to the geometry of the cavity itself, whereupon a pressure much higher than the injection force is applied to the solid-semisolid interface within the alloy, and sustained until full solidification is achieved. <IMAGE>
