Simultaneous Laser Plastic Welding
Jfortune has developed a new simultaneous laser plastic welding machine: this kind of laser plastic welding machine uses high power semiconductor laser as the welding light source, which has its good advantage: quick welding time, low thermal effect and also the welding thermal stress is relatively low, greatly improve the production efficiency and welding quality.
Laser plastic welding function:
Adopt high power 980nm semiconductor laser;
Include 10 sets (one set with 5 branches) simultaneous light source
Can freely set each welding area’s power and lighting time.
Adopt integrated water cooling and heating dissipation structure, save the assembly space.
Adopt auto changing tool, locking tool, and auto recognize nest number and version.
What is Laser Plastic Welding?
Simultaneous Laser Plastic Welding is the upper part which is transmitted laser by infrared band presses the lower part which is absorption layer together, through the laser beam energy to melt the lower part, quickly to cooling with the upper part under pressure. Simultaneous laser plastic welding has the advantage of quick welding speed, low thermal stress, minimal welding distortion, no vibration, no dust and high temperature during the whole welding process, it is used for automotive, 3C electronics, and medical…industries.
This laser plastic welding system uses semiconductor laser lighting source of closer infrared band, the lighting source and control system both uses cooling water method. We test this whole system strictly, which greatly improved the system’s tolerance degree and higher stability.
This optical structure design for supporting welding uses fiber optic positioning plate structure and wedge-shaped light guide plate, the optic positioning size is strictly designed per the testing result of welding efficiency and beam energy uniformity, the optical structure design greatly improve the welding efficiency, adopt simultaneous welding method, the features as below:
- Evenly distributed each fiber optical plate, flexible 3d welding, can distribute the welding optical fiber per product shape, also can make sure the welding stability;
- Optical plate design greatly improve welding efficiency, normally the welding time is 3-6s under good transmission;
- Focused energy for welding ribs can melt the lower part material quickly, it greatly reduced thermal distortion and internal stress in welded products.
- Each light is controlled separately, it is controlled separately according to the power and lighting time per adjustment requirement.

FAQ
What is the difference of simultaneous laser plastic welding machine and other types of laser welding machine?
—–>simultaneous laser plastic welding machine: laser generators can weld the plastic welding ribs at the same time, while other laser welding machines only has 1 generator, so only one infrared band to weld the whole cicle ribs.
Simultaneous laser plastic welding machine is widely used for the high end automotive lighting which needs high welding requirement. While small parts can be welded by other laser welding machines(1 generator), it can reduce the cost.
