PCT No. PCT/JP96/03151 Sec. 371 Date Jun. 26, 1997 Sec. 102(e) Date Jun. 26, 1997 PCT Filed Oct. 28, 1996 PCT Pub. No. WO97/15422 PCT Pub. Date May 1, 1997Molten resin, plasticized in the plasticization chamber, is fed to the injection chamber through a connection passage where it is measured. Before it is injected by the plunger, the connection passage is blocked and the molten resin is preliminarily compressed. This invention provides a method using a preplasticization type injection molding machine that controls the volume of the filled molten resin with little variation utilizing blocking and preliminary compression. By means of blocking or preliminary compression, the position movement by which the plunger moves from the position at which the measurement is completed is calculated, and the position at which the next measurement will be complete is corrected. Furthermore, the molten resin fill operation is done on the basis of the position of the plunger detected at the time of the preliminary compression.
