A method for manufacturing a plastic container by internal pressure forming including positioning a tubular preform between the die parts of a molding die having a die cavity; closing the molding die and forming or preforming a container from the preform using internal pressure, wherein a peripheral portion of the preform is pressed out of the die cavity through a die gap; laterally withdrawing the peripheral portion pressed out of the die cavity, as a result of which the container is divided into two container halves; and thermally separating plastic bridges and/or plastic threads which arise during the lateral withdrawal of the peripheral portion. Also disclosed is a molding die suitable for carrying out the method.

A preform conveying device (100) of the invention includes a control unit that detects an arriving time at which a conveyor jig arrives at a reference position based on an output of a first encoder, and commands a second motor to move a conveyor arm to a target position at regular intervals from the arriving time. The target position in each command is a position obtained by adding, to a current position of the conveyor jig which is obtained based on a latest output of the first encoder which was obtained when the command has been issued, a moving distance by which the conveyor jig has advanced during a delay time T which spans from a time when the latest output is outputted from the first encoder to a time when the command is received by the second motor.

The invention relates to a device and a method for semi-continuous blow moulding of fiber-reinforced, thermoplastic, endless, hollow-profile-shaped components with longitudinally constant or varying cross-sections, consisting of at least one consolidation tool, which, in its closed state, encloses a preform enclosing an elastically moldable pressure chamber.

A configuration including: a primary blow molding station including: an injection molding part configured to injection-mold a plurality of preforms simultaneously; a primary blow molding part configured to blow-mold the preform to form a first blow-molded article; and a first transport device including a first transport path and configured to intermittently circulate and transport a plurality of the preforms and the first blow-molded article along the first transport path at a predetermined interval; and a secondary blow molding station installed independently of the primary blow molding station, the secondary blow molding station including: a secondary blow molding part configured to blow-mold the first blow-molded article to form a resin container; and a second transport device configured to hold the first blow-molded article at a downstream side of the primary blow molding part in the first transport path and transport the first blow-molded article 40 to the secondary blow molding part.

A rigid connecting device for connecting the upper and lower surfaces inside an oil tank includes a connecting rod. The upper and lower sides of the connecting rod are each provided with a connecting end surface. The connecting end surface is provided with material-passing hole. The outer surface of the rigid connecting device is covered with high-density polyethylene. The upper and lower surfaces of the oil tank are connected by a connecting rod, and such arrangement is locally applied to areas where the rigidity of the oil tank is poor, so there are more effective space. The part of the rigid connecting rod contacting with the oil fuel is made of high-density polyethylene, so the requirements of strength and anti-corrosion can be satisfied.

A method for producing a foamed blow-molded article, which includes extruding a physical blowing agent-containing foamable molten resin downwardly through a annular die to form a tubular foamed parison, clamping the foamed parison between split molds, and then blow molding it. At the latest before completion of the clamping of the foamed parison between the split molds, a gas is blown toward an inner peripheral surface of an upper portion of the foamed parison, the bottom portion of which has been closed, from a gas ejection outlet located within the foamed parison at a position immediately below the annular die to widen the foamed parison.
