The present invention relates to a method for ultrasonic treatment of a plastic material, comprising the steps of: positioning the plastic material between a sonotrode and a counter-tool, bringing the sonotrode excited by means of an ultrasonic oscillation into contact with the plastic material during a welding phase, moving the sonotrode and the counter-tool towards each other during a holding phase, in which neither the sonotrode nor the counter-tool are excited with an ultrasonic oscillation so that a force F is applied onto the plastic material. In order to reduce treatment times, wherein at the same time the quality of the welding process is not impaired but is even to be improved, it is proposed according to the invention that the force F is varied during the holding phase.

A device for manufacturing a battery cell according to one embodiment of the present disclosure includes a sealing tool that forms a sealing part on the outer peripheral surface of a battery case to which an electrode assembly is mounted, wherein the sealing tool comprises a sealing surface that is brought into contact with the outer peripheral surface of the battery case, and wherein the sealing surface comprises a central surface and an inclined surface formed on at least one side of the central surface.

A structural member including a lightweight core, one or more skins, and a crosslinking nanolayer interposed therebetween that results in significant mechanical strength in the structure. The core is a polymer of reduced density by way of included voids, such as an open or closed cell foam, honeycomb, or corrugated structure. The core polymer has a lower density and may have a higher softening or melting temperature than the polymer skin materials. The core may be discontinuous at the interface with the skin such that only a small percentage of the core surface is actually in contact with the skin compared to the overall area of the interface. The skin may be a thermoplastic layer that attaches to the core material. The skin may be a composite material including non-thermoplastic reinforcements. The crosslinking nanolayer is covalently bonded to the surface of the core material and provides molecular compatibility with the skin material.

A system includes a body having a pair of cable jaws. The pair of cable jaws further includes a dispensing track on an inner circumference of the pair of cable jaws to retain a segment of a thermoplastic cable material. The system includes a piston. The piston is configured to secure an overlapping segment of the thermoplastic cable material at the weld area. An induction coil is configured to apply an electromagnetic field. The system includes a power supply.
