Laser welding case to laminated film
For welding of laminates, ultrasonic welding methods, etc. are being studied.
However, if there is a change in shape, it is necessary to make a new oscillator.
I also hear that it is difficult to design and manufacture oscillators for small parts.
“Isn’t it
possible to do what ultrasonic waves can do with lasers? If lasers can do it , even small parts can be done !! “
I tried to weld the laminate with a laser.
Laminated film structure used this time
Polyamide (PA) μm / Aluminum foil (Al) 40 μm / Polypropylene (PP) 40 μm
We tried welding with the PP side inside.
Laser welding
We were able to weld by devising how to apply the laser.
Even with strong force, it will not peel off.
When a tensile test was conducted with a universal testing machine (Orientec UCT-500 Co., Ltd.), a strength of 50 [N / 10 mm] was obtained.
We expect that this laser processing technology will be used in “vacuum packages for moisture proofing” and “outer bags for lithium-ion batteries.”
Laser Processing Services
Our laser processing technology enables high-speed, non-contact processing of fine holes with significantly smaller diameters and fewer burrs compared to other drilling methods such as punch presses and etching.
Laser Processing Machine Manufacturing
We manufacture and sell roll-to-roll laser drilling machines equipped with our original optical system GHS (Grand Helical Scan).
