Plastic laser welding method of welding
Common welding methods of plastic laser welding: In practical application, there are several different welding processes of plastic laser welding.
Sequential circumferential welding
The laser moves along the contours of the plastic welding layer and melts it, gradually bonding the plastic layer together. Or the sandwich can be moved along a fixed laser beam for welding purposes
Synchronous welding
A laser beam from a plurality of diode lasers is shaped by an optical element. The laser beam is directed to the contour line along the welding layer, while generating heat at the weld, so that the entire contour line is simultaneously melted and bonded together.
Scanning welding
Scanning welding is also called quasi-synchronous welding. Scanning welding technology integrates the above two welding technologies: sequential circumferential welding and synchronous welding. Using a reflector to generate a high-speed laser beam at a speed of 10 meters per second, it moves along the site to be welded, making the whole welding gradually heated and fused together.
Irradiation mask welding
The laser beam is positioned through the template to melt and bond the plastic. The template only reveals a small, precise welding spot on the plastic layer below. The laser beam only heats the part of the product that is not covered by the mask. Using this technique, high precision welding as low as 10 microns can be achieved.
