The invention relates to a process (100) for manufacturing an object (1) made of thermoplastic polymer composite from at least two parts (10) made of thermoplastic polymer composite, said thermoplastic polymer composite comprising a fibrous reinforcement and a thermoplastic polymer matrix, said process comprising the steps of: arranging (120) the two parts (10) made of thermoplastic polymer composite adjacently or overlapping at an assembly interface zone (11), and heating (130) to melt the thermoplastic polymer matrix at said assembly interface zone (11), so as to form an object (1) made of thermoplastic polymer composite comprising a welded interface (12).

A fusion welding device, comprising a fusion welding work motor, a fusion welding work moving assembly, and a fusion welding work fixed assembly, the fusion welding work motor being connected to the fusion welding work moving assembly by means of a transmission mechanism. The fusion welding device is provided with a central connection component that is able to rotate, and the central connection component is provided with a first input position, a second input position, and a locking structure connection position. The present fusion welding device is able to implement automatic band pressing and fusion welding work by means of relatively simple structural cooperation, and by means of differently transmitted front and back connections and changes in engagement, and is able to automatically lift the fusion welding work moving assembly without requiring a handle or related operations.

An automotive vehicle includes a body with a front portion and a rear portion. The vehicle additionally includes a spoiler coupled to the rear portion. The spoiler includes a first portion, a second portion, and a cap. The first portion includes a first plastic material, the second portion includes a second plastic material, and the cap includes a third plastic material. The second plastic material is distinct from the first plastic material. The second portion is disposed between the first portion and the cap. The second portion has a through hole extending therethrough. The cap has a diameter exceeding that of the through hole. The first portion and the cap are welded together via the through hole to mechanically secure the second portion to the first portion.

A first member formed of a thermoplastic resin molding mixed with a fiber material and a second member formed of a molding containing at least a thermoplastic resin are welded by friction stir spot welding using a double-acting tool for friction stir spot welding. An overlapping part between the first member and the second member is formed, and the tool is disposed against the overlapping part while the pin and the shoulder are rotated about the rotation axis. The pin is plunged into the overlapping part, and friction stir is performed to cause extension fibers to remain around a plunging region of the pin while the shoulder is retracted to release an overflow material. The shoulder is brought closer to the overlapping part to wrap the extension fibers into the overflow material when the overflow material is backfilled while the pin is retracted from the overlapping part.

The present invention concerns an ultrasonic vibration system comprising a sonotrode which has two sonotrode end faces and a circumferentially extending lateral surface connecting the two sonotrode end faces together, wherein the sonotrode has an elongate core element and at least one wing element, wherein core element and wing element respectively extend from the one sonotrode end face to the other sonotrode end face in a longitudinal direction, wherein the wing element has a sealing surface which is provided to come into contact with a material for processing thereof and is connected to the core element by way of a plurality of webs spaced from each other in the longitudinal direction of the core element, and a converter which is optionally connected to the sonotrode by way of an amplitude transformer. According to the invention it is proposed that the ultrasonic vibration system is connected to a machine stand by way of a mounting connected to the lateral surface.
