"Magnesium chips are filled into the dosing appliance and subsequently fed into the thixotrusion cylinder. The chips are conveyed by the screws and converted into a semi-solid state by the effect of temperature. During processing, a desirable globulitic grain structure in the material is achieved by the apparent high shear rates. The material is then shaped into the desired geometry by pressing it through a die at the foremost end of the extruder."
