A method of molding a metalized composite part. The method comprises: introducing particles comprising at least one metal into a gas stream; directing the gas stream toward a surface of a thermoplastic composite part, thereby depositing a metal layer on the composite part to form a metallized composite part; and molding the metallized composite part to introduce a bend without delamination of the metal layer from the metallized composite part.

A fully automatic mask production line is disclosed, including a mask material loading device, a folding device, a nose wire loading device, a mask body forming device, a mask overturning and conveying device, an ear loop welding device and a collecting device. The mask material loading device is adjacent to the folding device, the nose wire loading device is adjacent to the folding device, a feeding end of the mask body forming device is arranged opposite to the nose wire loading device and the folding device respectively, the mask overturning and conveying device is adjacent to the mask body forming device, and the ear loop welding device and the collecting device are respectively arranged on a conveying path and a conveying tail end of the mask overturning and conveying device.

A molding device is includes a mandrel that has an arc-shaped cross section; a roller that has a round-shaped cross section, is movable along a surface of the mandrel, and applies a pressing force to a material to be molded placed on the mandrel; a gripping unit that grips the material to be molded on an outside of the roller with respect to the mandrel and applies a tensile force to the material to be molded; a roller driving unit that moves the roller along the surface of the mandrel; a gripping-unit driving unit that moves the gripping unit. A control unit synchronizes a position of the roller and a position of the gripping unit with each other to control the roller driving unit and the gripping-unit driving unit so that the material to be molded is arranged in a direction perpendicular to a vertical direction of the mandrel.

Proposed is a pouch bending guide apparatus, for a secondary battery packaging system, in which a pouch sheet (2A) is folded by folding a bending jig (20) toward a base jig (30) with the pouch sheet (2A) placed on the base jig (30) and the bending jig (20) so as to mount a battery cell inside a pouch (2), the pouch bending guide apparatus including a bending knife (40) which supports, from the inside of the pouch (2), a bending lateral surface (2BS) of the pouch (2) formed while the pouch sheet (2A) is folded by the bending jig (20).

A composite material structure body production method includes a layering step of layering a plurality of fiber sheets to form a layered body having a deforming portion extending in one direction, and a forming step of performing bend-forming along a deforming line contained in the deforming portion and extending in the one direction, thereby causing the deforming portion to deform. The layering step produces the layered body in such a manner that the shape of the deforming portion is a shape wherein: the cross-section shape in the one direction and the cross-section shape in an intersecting direction that intersects with the one direction are bent or curved; and the length in the intersecting direction changes along the one direction.

Disclosed herein is an apparatus for folding a side extending outward from a cup part in a battery case of a pouch-type secondary battery. The apparatus can include a body having a plate shape, adjacent to the side, and disposed to be elongated in a longitudinal direction of the secondary battery, wherein the body includes, a heating part disposed at one side thereof to heat an inner portion disposed at a relatively inner side of the side, and a pressing part disposed at the other side thereof to press an outer portion disposed at a relatively outer side of the side. When the heating part heats the inner portion, the body rotates to allow the pressing part to press the outer portion.

A fiber product folding apparatus includes a first dashed-line cutting device used to form a plurality of first dashed lines on a first fiber product. Through control of the rotational speed of the first dashed-line roller, the interval between adjacent first dashed lines is adjusted. A first severing device receives the first fiber product with the first dashed lines by a predetermined length and cuts off the first fiber product. A second dashed-line cutting device is used to form a plurality of second dashed lines on a second fiber product. Through control of the rotational speed of the second dashed-line roller, the interval between adjacent second dashed lines can be adjusted. A second severing device receives the second fiber product that includes the second dashed lines by a predetermined length and cuts off the second fiber product. Finally, the first fiber product and the second fiber product are conducted to pass between a first folding roller and a second folding roller to proceed with folding. Since the dashed line interval of the fiber products is the size or length of a single sheet of fiber product, controlling the rotational speeds of the dashed-line rollers would allow for adjustment such that folding can be performed for multiple forms.

A disclosed sizing roller apparatus for a folding process of a battery cell includes: a table fixing and supporting a battery cell; a base plate disposed on a side of the table; a plurality of sizing rollers disposed on the base plate and each having a rotation axis, which is inclined inward toward a folding portion of the battery cell, to press the folding portion of the battery cell in contact with the folding portion; and a plurality of air spray nozzles disposed on the base plate and spraying air to the plurality of sizing rollers.
