    摘要: A transfer molding machine for filling at least one cavity of a mold with a resin by means of a plunger including a resin pressure sensor for sensing the resin pressure in the mold, and a control device for controlling the pressure applied to the plunger to drive same in such a manner that an arbitrarily selected primary pressure higher than a holding pressure is applied to the plunger to drive same until the pressure of the resin charged into the mold which pressure is detected by the resin pressure sensor in the mold reaches a predetermined pressure level and a secondary pressure corresponding to the holding pressure is applied to the plunger to drive same after the predetermined pressure level has been exceeded by the pressure of the resin being charged into the mold sensed by the resin pressure sensor in the mold, and a warning device that issues a warning when the pressure applied to the plunger to drive has exceeded a predetermined pressure.
