    • 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.
    • 一种用于通过包括用于感测模具中的树脂压力的树脂压力传感器的柱塞的树脂填充模具的至少一个模腔的传送成型机,以及用于控制施加到柱塞以驱动其的压力的控制装置 以这样的方式,将高于保持压力的任意选择的一次压力施加到柱塞以驱动,直到被模具中的树脂压力传感器检测到的压力中的树脂的压力达到预定压力水平 并且在由模具中的树脂压力传感器感测到的模具中充填的树脂的压力超过预定压力水平之后,将对应于保持压力的次级压力施加到柱塞以驱动其,并且警告装置 当施加到柱塞驱动的压力已经超过预定压力时发出警告。
