Heat transfer in glass-forming operations depends on many factors,,e.g. the properties of the glass, heat-transfer coefficients at the glass/mold and mold/air interfaces, the characteristics of the mold material, and the glass/mold contact time. Using a computer model developed for one-dimensional heat flow, the influences of these factors were calculated. The heat-transfer parameters, which were analyzed individually, include e.g. the glass surface temperature, the peak inner mold surface temperature, the quantity of heat transferred from glass to mold during a steady-state cycle, and the amplitude of mold surface temperature oscillation at steady state. Comments are given on the significance of the results.
