Abstract
A provisional temperature estimating mathematical expression is set in accordance with which plasticizing conditions used as terms are to be multiplied by unknown coefficients. Then, a given number of experiments not smaller than the number of the unknown coefficients are conducted while the plasticizing conditions are varied, so as to acquire various experimental data. The unknown coefficients are converted into known coefficient in accordance with the acquired experimental data so as to provide a complete temperature estimating mathematical expression, on the basis of which a plasticized resin temperature and noise-outlet resin temperature are determined arithmetically.
