2.Effects of Technological Factors on Density of Expandable Polystyrene (EPS) Pattern for Lost Foam Casing
3.In this paper, the effects of bead diameter, pre-expansion time, pre-expansion temperature, molding steam pressure and molding time of pattern on the density of expandable polystyrene (EPS) pattern were studied systematically.
4.The research results indicated that among these technological factors studied, the influence of pre-expansion temperature on the density of expandable polystyrene (EPS) pattern was greatest, bead diameter and pre-expansion time were next respectively, molding steam pressure and molding time were small relatively.
