A metal working process that uses the friction developed between a feedstock and the groove of a rotating wheel for the continuous extrusion of a range of nonferrous materials. The feedstock, which is usually in the form of rod or continuously cast bar, is drawn into the chamber formed between a groove machined in the rotating wheel and a closely fitting shoe. The passage is obstructed by an abutment supported by the shoe and the feedstock is prevented from continuing its progress around the circumference of the wheel. The frictional forces that develop between the material in the groove, the shoe and the abutment cause the feedstock to increase in temperature until the material develops enough plasticity to extrude through a die supported in the shoe.
