A method for manufacturing a flexible metal-clad laminated plate includes the steps of: (a) obtaining a laminated body by laminating a polyimide resin film including a non-thermoplastic polyimide layer and an adhesive layer containing thermoplastic polyimide, the adhesive layer being provided on at least one side of the non-thermoplastic polyimide layer, and a metal foil; and (b) subjecting the laminated body obtained in the step (a) to heat treatment under an inert gas atmosphere and a pressure of 0.20 to 0.98 MPa at a temperature of a glass transition temperature Tg of the thermoplastic polyimide20 C. to the glass transition temperature Tg+50 C.

A system and method for welding thermoplastic components by positioning and moving a heated plate between the components to melt their respective faying surfaces, and as the plate moves, pressing the components together so that the melted faying surfaces bond together as they cool and re-solidify, thereby creating a composite structure. The plate has a heated portion which is positioned between and heated to melt a portion of the first and second faying surfaces. A manipulator mechanism moves the plate along an interface from between the portion to between a series of subsequent portions of the first and second faying surfaces, thereby welding the thermoplastic components along the entire interface to create the composite structure. The heated portion may contact the faying surfaces and melt them through conduction, or may be suspended between them and melt them through radiation and convection.

An apparatus to join two panels together includes a chamber, a horn positioned within the chamber, the horn moving reciprocally within the chamber, and a set of heating elements positioned about the horn to heat the horn. One of the panels has a post molded to it, the post extending through the other panel, and after the horn is heated an end of the horn is placed on top of the post and is ultrasonically vibrated to form a head of the post to join the two panels together.

The present invention relates to a machine comprising: an unwinding unit (11) for unwinding a flexible band (1), a folding unit (14) of a flexible band (1), a drive unit (31) configured for moving the flexible band (1) in a forward movement direction (DA), a welding unit (16) and a cutting unit (17) for cutting the flexible band, wherein the cutting unit (17) is a laser beam cutting unit (53) separating each individual flexible package from the flexible band (1) and providing a fill opening in each flexible package by means of at least one fill opening cut. The laser beam cutting unit (53) has associated therewith a separator device, movable in a vertical direction and including an insertable separator element (41), interposed between the opposite faces of the folded flexible band (1), in an area adjacent to the fill opening (3), for separating the opposite faces of the flexible band (1) during cutting operations to prevent the fusion thereof.

An infrared welding system for joining two parts made of thermoplastic material comprises a pair of infrared heaters for heating the two parts while spaced from each other; and energizing the infrared heaters to emit infrared heat and directing the emitted infrared heat onto selected portions of the opposed surfaces of the parts to melt at least portions of the opposed surfaces, while directing an inert gas onto the selected portions to prevent ignition of the melted thermoplastic material. The two parts are clamped together by moving at least one of the parts toward the other part to press the melted surfaces of the parts into contact with each other. The parts are cooled while they remain clamped together to solidify the molten thermoplastic material and thus weld the two parts together.

A process for welding a first molding to a second molding. The process uses an implement including first and second external surfaces. Each external surface further includes a duct. An end of the first molding is heated by a hot gas while the end is at a distance from the duct-entry plane in the range from 3 mm outside the duct to 10 mm inside the duct. A junction area of the second molding is heated by a hot gas while the junction area is at a distance from the duct-entry plane in a range from 3 mm outside the duct to 10 mm inside the duct. The heated end and the heated junction area are then brought into contact with one another and cooled, forming a weld between the first molding and the second molding. Also disclosed is a welded molding obtainable by the process of the invention.
