    摘要: A blow molding apparatus that supplies a pressurized liquid into a bottomed tubular preform fitted to a mold used for blow molding and molds the preform into a shape conforming to a cavity of the mold, the blow molding apparatus including: a blow nozzle fitted to a mouth tubular portion of the preform; a plunger pump configured to supply the pressurized liquid into the preform through the blow nozzle; and a control device configured to change an actuation rate and an actuation force of the plunger pump during the supply of the pressurized liquid into the preform to regulate a peak pressure of the liquid supplied into the preform to be from 3.5 MPa to 5.0 MPa.

    摘要: A container production method by liquid blow molding. The method includes a pushing step in which a liquid is collected from a preform at the timing at which the pressure inside of the preform starts rising by pushing of the expanded and deformed preform by a movable mold portion of a blow molding mold so that the rise in the pressure is suppressed or prevented.

    摘要: A liquid blow molding device and a liquid blow molding method are configured to supply pressurized liquid to a preform mounted to a mold to mold the preform into a shape along a cavity of the mold, and includes a blow nozzle fitted into a mouth portion of the preform, a plunger pump configured to supply pressurized liquid to the preform through the blow nozzle and a controller configured to control operation of the plunger pump. The controller controls operation of the plunger pump by position control in which a plunger of the plunger pump is moved from an original position to a predetermined final position with a predetermined operating force.
