摘要

Process for thioextrusion of lightweight metals comprises charging an extruder with the starting material; heating and conveying the material in the extruder. The heated material experiences shearing in the extruder during the course of the conveying and leaves the extruder through the outlet nozzle or molding tool. Heating is carried out above the Tsolid temperature. An independent claim is also included for the extruder containing two spiral shafts. Preferred Features: The starting material is fed to the extruder in solid or molten form.
