IPC: B29C45/50
Filed: 2000-03-02
Abstract: PROBLEM TO BE SOLVED: To reduce the density variability of a molten resin in storage as soon as possible through a measuring procedure by continuing the pressure control of a screw even when the revolution of the screw is suspended or at the end of a measuring process close to the suspension and ending the pressure control when the transfer of the screw in the axial direction is stopped or is close to the stoppage.

Next the resin pressure value of a load cell 10 which becomes higher by a molten resin sent to the tip side following the revolution of the screw 2, is controlled in such a manner that the resin pressure value coincides with a set value.  The pressure control of the resin is continued even when the revolution of the screw 2 is stopped at a position for the screw 2 in which a single shot amount of the resin is stored or at the end of a measuring process close to the stoppage, and the pressure feedback control is stopped when the transfer in the axial direction of the screw 2 is stopped or it is close to the stoppage. Thus it is possible to reduce the density variability of the molten resin measured and stored as soon as possible.
