Abstract
Hot chamber die casting (HCDC) process is designed to achieve high dimensional accuracy and surface hardness (SH) for industrial applications (like machine tool components). In the present study, outcome of Taguchi model has been used for developing a mathematical model for SH; using Buckingham’s π-theorem for HCDC process. Three input parameters namely pressure at 2nd phase; metal pouring temperature and die opening time were selected to give output in form of SH. This study will provide main effects of these variables on SH and will shed light on the casting hardness mechanism in HCDC process. The comparison with experimental results will also serve as further validation of model.
