A biaxial stretch blow molding device comprises: a first guide shaft which is erected on an upper base and to which a blow core fixing member is slidably coupled; a second guide shaft erected on the stretch rod fixing member; a support member fixed to the first guide shaft and provided with a guide hole through which the second guide shaft is slidably inserted; a first drive device that moves the blow core fixing member forward and backward independently of the stretch rod fixing member; and a second drive device that moves the stretch rod fixing member forward and backward independently of the blow core fixing member.

A separating device for separating individual container products from a frame assembly of plastic material, particularly polypropylene, has at least one stamping device (36) that at least partially separates the respective container product from a frame waste. By the stamping device (36) including a free fall body (52) separating the respective frame waste from the associated container product from an initial position during free fall, the separation can be carried out with very high speed (free fall) and additional mechanical components for applying a constraint force on the stamping body during the creating of the separating line can be omitted.

A method of manufacturing a container by liquid blow molding includes: a liquid blow molding step of supplying a pressurized liquid to inside of a preform placed in a mold, and molding the preform into a container body containing the liquid; a placement step of placing the container body in a cup for containing a bottom part of the container body, at a mold opening position of the mold; and a conveyance step of conveying the cup holding the container body from the mold opening position to a capping position.

A device for reducing the microbiological contaminants of container products made predominantly of plastics materials feeds a plastics granulate to an extruder assembly (19) that melts the granulate. The granulate is subsequently supplied to a form-fill-seal machine for producing a container product. A guide assembly (35) guides the plasticated plastic material from the extruder assembly (19) to the machine. At least one guide assembly (35) has at least one flow or channel guide (41) for the melted plastics material, so that microbiological contaminants are guided predominantly into the interior of the wall of the polymeric tube that interior is enclosed by regions of the plastic material that are less contaminated.

A food and/or beverage packaging container comprises a blow-molded body having a length, a diameter and side walls having a wall thickness. A wide mouth neck extends from the body and is trimmed to a finished configuration. The neck has a diameter and a wall thickness. The length, the diameters and the wall thickness' are pre-selected such that the container comprises one or more selected physical performance features. Systems and methods of use are disclosed.

A container manufacturing device having a preform manufacturing portion, a conveyor, a blow molding device, where the preform is to the blow molding device while maintain the residual heat from the preform manufacturing portion. The preform manufacturing portion includes a molding die and a feeder for supplying a molten thermoplastic resin to a cavity of the molding die. In the blow molding portion, liquid is used to mold the preform into a container of a predetermined shape.

A method for forming a bladder comprises providing a mold including a chamber wall having a first height and a cavity wall having a second height. The cavity wall is surrounded by the chamber wall and defines a plurality of cavities. A first sheet, a second sheet, and a gasket are provided to the mold, whereby the gasket is disposed adjacent to at least one of the first sheet and the second sheet. The mold is moved such that a peripheral portion of the at least one of the first sheet and the second sheet and the gasket are compressed by the chamber wall. A first pressure is provided between the first sheet and the second sheet through the gasket to form a plurality of chambers, and the mold is moved to a second position to seal the first pressure between the first sheet and the second sheet.

The present application provides: first base members that respectively hold split molds disposed at both ends in a second direction, and are fixed to a mold clamping plate; second base members disposed between the first base members and having the split molds other than the split molds fixed to the first base members fixed thereto; and coupling members that couple the first base members and the second base members in a state that allows each of the pair of split molds to come into contact or separate. The present invention is configured such that the plurality of second base members follow the movement of the first base members.

The present embodiments provide an apparatus for producing a pressure vessel blank, comprising at least one connection element, a multi-part blow-moulding tool, and at least one blowing pin. The present embodiments further provide a pressure vessel comprising at least one connection element, a pressure vessel blank, and a supporting shell connected to and supporting the pressure vessel blank. An aspect of the present embodiments provides a process for producing a pressure vessel blank using an apparatus comprising at least one connection element that enables a shortened time for producing a pressure vessel blank with increased stability under pressure.

A biaxial stretch blow molding device comprises: a first guide shaft which is erected on an upper base and to which a blow core fixing member is slidably coupled; a second guide shaft erected on the stretch rod fixing member; a support member fixed to the first guide shaft and provided with a guide hole through which the second guide shaft is slidably inserted; a first drive device that moves the blow core fixing member forward and backward independently of the stretch rod fixing member; and a second drive device that moves the stretch rod fixing member forward and backward independently of the blow core fixing member.
