PROBLEM TO BE SOLVED: To mold a precise molding in need of special quality with the use of a milti-cavity mold. SOLUTION: The temperatures of resins 25a, 25b injection-packed in cavities 5a, 5b formed in molds 1a, 1b are measured immediately before gates 21a, 21b by temperature sensors 23a, 23b set in the cavities 5a, 5b respectively. Corresponding to the individual temperatures/temperature difference of/between the resins 25a, 25b, a servo-motor is driven, gate cut pins 16a, 16b inserted into the cavities 5a, 5b are moved to/from the gates 21a, 21b, and the distancesΔta,Δtb between the gates 21a, 21b and the pins 16a, 16b are adjusted so that the amount of the resin to be packed in each cavity 5a, 5b is adjusted.
