Abstract
Metallic bodies are heated up to a predetermined temperature between the solidus and the liquidus to produce a semisolid state by supplying the metallic bodies with different amounts of energy over time. The metallic bodies are initially heated with a higher amount of energy, whereafter the supply of energy is lowered. Varying amounts of energy may also be employed to control the desired temperature as a function of shaping pressure or cycle time of the shaping machine.
