This study was developed based on the Wolfram Mathematica software to determine the temperature spectral and temperature gradient transmittance in the mold’s wall and core, in order to determine the influence of the material thermal conductivity to the mold temperature gradient, as well as evaluating the effect of changing the position of the mold surface to the thermal gradient in the mold. | Determination of temperature gradient and spectrum in the mold’s core and wall by solving the differential equations using Wolfram Mathematica software
