Sub-ambient pressure morphology control process for use in molding extruded polymer foams, and parts produced therefrom
A method of sub-ambient pressure processing of blow-molded polymer foams and skin-over-foam sandwich panel configurations for lightweight components having improved structural properties. The method can create either skinned or un-skinned foams that offer smooth interior and exterior surfaces, zero or controlled surface porosity, skins of pre-defined thickness, and foam cells that are expanded and oriented normal to the material plane, effectively spherical or polyhedral in nature, and offering improved bending and compressive strength.

Reduced material container and method of forming same
Systems and methods for making a reduced material container are provided that hold a preform adjacent to an open end of the preform, stretch the preform, close a mold about the stretched preform to form a truncated preform, and introduce a pressurized fluid into the truncated preform to expand the truncated preform and form the reduced material container. A stretch rod can be inserted into the preform to mechanically stretching the preform. The mold accepts the preform at a first end thereof, has an open state and a closed state, and the closed state forms a cavity defining an internal surface having a second end located remotely from the first end. A first length is defined by a distance between the first end and the second end, the stretch rod mechanically stretching the preform to a second length, the second length being greater than the first length.

CONTAINER MANUFACTURING APPARATUS
A container manufacturing device is provided. In detail, the container manufacturing device for performing manufacture of a container pre-form and container molding in a single station via one stop. The container manufacturing device includes a pre-form molding module configured to form a shape of a pre-form of a container using a resin material, an injection module connected to the pre-form molding module and configured to supply the resin material to the pre-form molding module, a container molding module configured to inject air to a pre-form completed by the pre-form molding module to expand the pre-form and to form the shape of the container, and including a container mold, and a rotary table with a rib plate suspended thereon while rotating between the pre-form molding module and the container molding module, the pre-form or the container being mounted on the rib plate.
Method for producing containers, comprising a delayed boxing operation
A method for producing a container (2) from a blank (3) in a mold (1) provided with a wall (4) and a mold bottom (8) that is movable relative to the wall (4) between a retracted position and a deployed position, the method including: a phase of introducing the blank (3) into the mold; a preblowing phase including the injection, into the blank (3), of a fluid pressurized to a so-called preblowing pressure, a blowing phase following the preblowing phase and including the injection, into the blank (3), of a fluid pressurized to a so-called blowing pressure greater than the preblowing pressure; a boxing phase including the displacement of the mold bottom (8) from the retracted position thereof to the deployed position thereof, initiated after the pressure in the blank (3) has reached the blowing pressure.

Apparatus and method for transforming plastic parisons into plastic containers with air discharge
A blow mould for producing plastic containers comprises at least two blow mould parts and a hollow space formed from the at least two blow mould parts at which plastic parisons are transformed by an application of a flowable medium to the plastic containers. The hollow space includes an interior wall that has a contour which produces a predetermined configuration of the plastic containers. A first portion of at least two blow mould parts produces a bottom of the plastic containers. A second portion of the at least two blow mould parts has an opening region for discharging a gaseous medium during an expansion process of the plastic containers. The opening region extends along a first line and a second line, wherein the first and second lines run at least in some sections of the blow mould at an angle different from 0 relative to one another.
