Manufacture of Automotive Components By Semi-Liquid Forming Process 91A113
Semi-liquid forming process, applied to pressure die-casting,
permits to obtain low cost components with high qualitative
characteristics and adequate mechanical performances.
The technology is based on the employment of material with
globular microstructure (flow-cast alloys) obtained subjecting a
metal alloy at the time of solidification to an elevated shear
rate. Such microstructure permits the accomplishment of
conventional forming processes at temperatures in solidification
The particular fluid-dynamic properties of the semi-liquid
slurry and the lower injection temperature allow to obtain casting
with improved soundness, without need of impregnation, and to
extend die life.
The present work describes the Weber (Magneti Marelli) activity
of the process industrialization and some applications for the
manufacture of automotive components.
