Features
The WFD series laser plastic welder is a diode laser that uses diode materials to illuminate between energy bands. Two parallel mirror surfaces inside the diode are formed as a resonant cavity, which illuminates the light, and outputs laser of wavelength 915 nm.
With fiber transmission, a non-contact long-distance operation is convenient for integration with the automated production line. The laser has current feedback closed-loop control, real-time monitoring and adjustment of the output laser to ensure the stability; uniform beam energy distribution, large beam size.
- Low maintenance costs and low power demand, zero material consumption, lifetime maintenance-free,electro-optical conversion efficiency up to 47%.
- Integrated design, easy to integrate into a machine.
- Compact design
- Large beam size
Application and Samples
What is laser plastic welding?
Laser welding plastic, the laser beam, after transmission through the upper-layer transparent material, will be absorbed by the lower layer. The laser energy, after being absorbed, will be transformed into heat. Since two layers of materials are forced together, the heat will be conducted to transparent layer from absorbing layer, which would make the two layers of materials melt and connected. At the same time, the internal pressure occurs because of the material’s thermal expansion. The total effort of the internal and external pressure can make sure two layers are firmly welded. For the product lower-layer material does not absorb laser, additive needs to be applied to the lower layer.

Application of laser plastic welding in the automotive industry
- Suitable for welding plastic bodies such as automobile taillights. The worktable adopts a three-axis method. The product is manually loaded on the fixture, and the Y-axis is fed to the welding position for rapid welding.
- Suitable for the welding of automobile automatic door locks and other similar products. The workbench adopts double Y-axis and dual station mode to realize the simultaneous loading and unloading and laser welding, which improves the laser’s utilization rate.
- Suitable for welding of automobile dashboards and other similar products. The worktable adopts manual loading and unloading and Y-axis feeding. Weld the product through the four-axis linkage welding head.
