An assembly method between a part made of metal material and a part made of organic matrix composite material, said method having a step of providing two parts, each including a surface to be welded, and the surface to be welded of said composite part is made up, at least partially, of an exposed portion of at least one metal insert which is partially embedded in said composite part; positioning said surfaces to be welded opposite and separated from each other; and projecting, at high speed, the surface to be welded of the metal part or the exposed portion of the metal insert, onto one another, to obtain high-speed clamping to one another and to obtain a weld between the exposed portion of the metal insert of the composite part and the complementary portion of the surface to be welded.

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.

In a process for welding plastic parts together, an IR shield redirects IR radiation emitted from a heater of a heating tool so that IR radiation which would otherwise be directly incident on certain portions of a plastic part and/or on other parts of the heating tool is avoided.

The present invention relates to plastic welding process comprising using a dynamic heatsink that minimize the temperature rise of the predetermined surface whereby the surface quality of plastic welding is maintained.

Methods and apparatus' for induction welding a first workpiece to a second workpiece at a welding region may include a metallic strip. The metallic strip may be a mesh. The properties of the metallic strip, such as, for example, pore size, thickness, and density, may be configured to conduct heat uniformly across the welding region and prevent eddy current formation across a workpiece. The metallic strip may be embedded in a workpiece or may be fixed to an induction welding tool that acts on the welding region during induction welding. A removable polymer tape may be disposed between a workpiece and a metallic strip fixed to an induction welding tool. The workpieces may be thermoplastic composite structures and thermoplastic composite stiffeners in aircraft structures.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

A belt splicing machine includes two pressing plates respectively arranged at an upper side and a lower side and opposite to each other. The pressing plate located at the upper side and the pressing plate located at the lower side are respectively mounted on a support located at the upper side and a support seat located at the lower side. A heating sheet, a clamping plate, and an airbag are successively arranged between the pressing plate located at the upper side and the support seat from bottom to top. The clamping plate is fixedly connected to the pressing plate. A connecting plate is arranged between the airbag and the clamping plate. The clamping plate is fixedly connected to the support seat. A plurality of elongated grooves are formed on the lower side surface of the connecting plate along its length direction.

The present invention relates to trim component for covering an interior space of a means for transporting passengers, in particular of a vehicle, comprising a support element which has at least one separation surface and at least one edge-folded section abutting the separation surface, wherein the support element has at least one folded edge which includes at least one edge-folded section. Moreover, the present invention relates to a method for producing such a trim component.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

A welding process includes inserting two work pieces inside a sealable container. Placing the container with the two work pieces inside into a welding device and welding the two members together while inside the container.
