Process for coating a preformed substrate (1), comprising providing a semi-finished product (2) comprising the preformed substrate (1) and a coating layer (3), providing a mould (4) comprising a first (5) and a second half-mould (6), the first half-mould (5) comprising an elastically deformable membrane (8) which at least partially forms a respective conformation surface (7), arranging the semi-finished product (2) on the second half-mould (6), putting under depression a fluid (11) acting on the membrane (8) to maintain the membrane (8) adherent to a main body (50) of the first half-mould, closing the mould (4) maintaining a free distance between the conformation surface (7) of the first half-mould (5) and the semi-finished product (2), pressurizing the fluid (11) to expand the membrane (8) towards the second half-mould (6) for compressing the semi-finished product, maintaining the membrane (8) in the second configuration, heating the semi-finished product (2) for firmly fixing the preformed substrate (1) and the coating layer (3) to each other.

A method is provided of bonding together at least two parts. The method includes assembling together at least two parts and at least one adhesive layer, the adhesive being configured so that its adhesive power increases on heating as a result of it polymerizing, at least one of the parts being made of composite material or of metal, the adhesive layer being present, after assembly, between the parts, the assembled together parts and the adhesive being present in a chamber defined by a wall, the wall having an inside face situated facing a first part present between the adhesive layer and the wall, the first part being intended to be bonded to a second part and only a fraction of the second part being present inside the chamber; and applying a liquid against the wall on its side opposite from the chamber.

The present invention relates to a method for evaluating an assembly by welding of parts made of thermoplastic materials, to a test piece and its associated uses, to an installation for implementing this method and to the associated welding system.

A heat seal device includes at least two primary biasing members and a secondary biasing member. These biasing members are located between a slider and a first heat seal member to bias the first heat seal member towards a second heat seal member when bag components are sandwiched by the first and second heat seal members. The primary biasing members are arranged in a straight line in the first horizontal direction. The secondary biasing member is arranged offset from the primary biasing members in a second horizontal direction perpendicular to the first horizontal direction. The heat seal device is configured to allow adjustment of biasing force applied to the first heat seal member by the secondary biasing member.

The present invention relates to a method for sealing a pouch-type secondary battery and may provide a method for sealing a pouch-type secondary battery, the method including: a first sealing process of vertically pressing a sealing area of upper and lower pouches through a sealing apparatus; and a second sealing process of moving the sealing apparatus outward from the inside of the pouch in the state of pressing the sealing area of the upper and lower pouches through the sealing apparatus.

To achieve universal welding of thermoplastic workpiece parts with simple equipment, an infrared light transmission welding method is disclosed in which simple polychromatic, incoherent infrared light is generated by a simple infrared light source and is directed through a first workpiece part to a weld point for the purposes of connection to a second workpiece part. In particular, the infrared light is directed through a transparent bracing element.

The present invention relates to a sealing device, and more particularly, to a sealing device in which a temperature of a sealing surface of the sealing device is constantly maintained has an appropriate solvent is continuously heated using a phase change, thereby manufacturing a pouch sealing part having excellent quality in a product of a pouch type secondary battery.

The sealing device according to the present invention includes a sealing body provided with a sealing surface, which is configured to seal a sealing target object, on one surface thereof, a solvent that is in contact with the other surface of the sealing body to supply heat to the sealing body, and a heat source configured to heat the solvent so that at least a portion of the solvent is phase-changed into a gas.
