The invention relates to a method for manufacturing a finished part comprising: a step of placing a trimmed finishing shell inside a heated mold chosen from a first mold referred to as a female mold and a second mold referred to as a male mold in the form of a punch, a step of heating a structural part made of a composite material up to its melting point, a step of placing the structural part on the finishing shell, a step of shaping the structural part against the finishing shell by means of the male mold in the form of a punch cooperating with the female mold, such that the finishing shell is fixed to the structural part that was shaped to obtain the finished part.

There is provided a method of making a curved barrier film, including: depositing a barrier layer between a first organic layer and a second organic layer to form a barrier film; and thermoforming or vacuum-forming the barrier film from a flat barrier film to a curved barrier film; wherein the barrier film includes the barrier layer having two opposing major surfaces, wherein the barrier layer includes buckling deformations and non-buckling regions; the first organic layer in direct contact with one of the opposing major surfaces of the barrier layer; and the second organic layer in direct contact with the other of the opposing major surfaces of the barrier layer.

A molding system capable of reducing molding defects including first and second parison forming devices; first and second molds configured to be opened and closed; and a control unit. The first parison forming device comprises a first extruder, a first accumulator, and a first injection head, the first parison forming device is configured to form a first parison by injecting a first molten resin from the first injection head after the first molten resin extruded from the first extruder is accumulated in the first accumulator, the second parison forming device comprises a second extruder, a second accumulator, and a second injection head, the second parison forming device is configured to form a second parison by injecting a second molten resin from the second injection head after the second molten resin extruded from the second extruder is accumulated in the second accumulator.

Method of forming, in particular a thermoforming method, a foil into a container, in particular a brewing container, especially a coffee capsule, using a plug assist and/or pressure difference in axial main forming direction, directing the foil into a forming tool creating a blank with a cavity and pressing the foil towards the forming tool bottom in order to create a floor for the blank and characterising the method in that the floor of the blank experiences a material distribution, especially a material shifting and/or material compression, during which a constant pressure difference within the blank's cavity is guaranteed and a circumferential annular gap is created.

A system for forming a deep drawn helmet and method therefor are disclosed. The system includes a forming draw ring and a non-forming draw ring and supports a prepreg stack between a forming aperture of the forming draw ring and a non-forming aperture of the non-forming draw ring. The system clamps a flange portion of the prepreg stack between a contact surface of the forming draw ring and a contact surface of the non-forming draw ring, which forms a clamped assembly of the rings and the prepreg stack. The system then forms a deep drawn helmet preform from the prepreg stack of the clamped assembly. The same system or a different forming system then consolidates one or more of the preforms into a final deep drawn helmet. The system can control sliding of the flange during forming of the helmet preform without reducing the flange clamping force.

A web transport assembly for moving flexible sheet material in a manufacturing process. The web transport assembly comprises first and second gripper chains spaced apart from one another to define a path of travel of the flexible sheet material, each of the gripper chains having a plurality of saddle links and a plurality of gripper links. First and second parallel rail structures are respectively aligned with the first and second gripper chains. In addition, upstream and downstream hubs are associated with each of the first and second gripper chains to define a continuous loop about which the associated gripper chain extends. At least one of the hubs includes a driven sprocket having a plurality of teeth engaging the associated gripper chain. The saddle links have a pair of spaced apart extension portions defining a spaced in which an associated one of the rails is received. The gripper links have a gripper mechanism that is configured to clamp a side of the flexible sheet material.

Disclosed is a method for manufacturing a secondary battery. According to the present invention, a problem of weakening durability of a pouch, which may occur in a process of forming cups having different depths in the pouch may be solved.

An apparatus for manufacturing a pouch-type battery case according to an embodiment may be configured to mold a pouch sheet. The apparatus for manufacturing the pouch-type battery case may include a forming device configured to mold a cup part in the pouch sheet, a first roller disposed behind the forming device in a moving direction of the pouch sheet and rotating in contact with one surface of the pouch sheet, and a second roller disposed to face the first roller with the pouch sheet therebetween and rotating in contact with the other surface opposite to the one surface of the pouch sheet. Any one of the first roller and the second roller may have an outer diameter that gradually decreases inward in a thickness direction, and the other one of the first roller and the second roller may have an outer diameter that gradually increases inward in the thickness direction.
