While there are a number of methods for joining plastics, it is common to use ultrasonic and impulse welding to join films.
In impulse welding, one or more electrically heated bars/elements are pressed against the surfaces of the films to be welded until the films melt and bond at the faying surfaces.
Chase Machine & Engineering is the world leader in the design and manufacture of continuous-web machinery, employing ultrasonics, impulse welding, adhesive, hot air and laser technologies.
Our Material Applications Lab is equipped with ultrasonic, laser, impulse welding and web-handling equipment, and can be reserved for testing products or assembly methods.
For example, in the case of impulse welding
, local collapse or sample displacement occurs, however with laser microwelding, this deformation is restricted by joint geometry and is controlled by local thermal expansion (15).
In this article, Part 1, coupled squeeze flow and healing models are developed and verified with experimental work based on standard industrial welding techniques, such as impulse welding using thermal histories that were experimentally measured.
They were selected because they represent materials that will probably be used in MEMS and microfluidic applications, so the results from the impulse welding could be used to analyze microwelds in Part 2.
Useful results for temperature development were obtained in cases of high absorption constants by setting up an analytical model by analogy to single-sided heat impulse welding
