Influence of process parameters on surface appearance and roughness of a low Si containing Al-alloy, in semisolid casting

• The visual appearance and surface roughness were experimentally investigated inindustrial scale for a low silicon containing aluminium alloy cast in semisolid state integrated withHPDC machine. A visual comparative technique and surface roughness in the form of the Rq valuewere used to evaluate the surface appearance and the surface roughness respectively. The resultswere investigated statistically to find significant models. It was shown that high quality appearance,following a comparative scale, was possible using high die temperature and high injection speed. Itwas also found that improving the surface roughness will deteriorate the visual appearance.
