To produce a highly accurate molded product by making molding quality hard to be affected with respect the fluctuations of the resin amt. of the resin matrix charged in a mold.
After a resin matrix 11 having an almost final shape is inserted into the cavity 7 of a mold to perform mold clamping, the resin matrix 11 is heated to a softening temp. or higher. A movable transfer piece 5 is moved upwardly in such a state that pressure is applied to the upper surface of the piece 5 by the thermal expansion of the resin matrix 11 under heating and, even if the resin anat. (wt.) of the resin matrix 11 charged in the cavity 7 varies, predetermined resin pressure is applied to a transfer face. At this time, the excessive amt. of the resin matrix 11 enters the gap 7 provided to the surface of one of upper and lower molds 2, 3 to adjust a proper resin amt.
