Abstract:	This work is a contribution to improve understanding about the behaviour of components produced by semi-solid processes. The present study shows the effect of different conformation parameters on automotive cranking cover production obtained by Semi-Solid Rheocasting Process (SSR®). The components were produced using EN AC-46500 alloy, by an industrial plant with a 700 Ton HPDC machine and an IDRA SSR Station. The process parameters studied were slurry temperature, agitation time, speed injection and lubrication system. The characterization was carried out by microstructural analysis, X-rays and mechanical tests. The components show good mechanical properties, similar to those obtained by die cast. The process was simulated using the PROCAST program.
