Plastic Welding
Welding of plastics by diode laser supplements traditional welding processes, such as ultrasonic, vibration or heat plate welding.
Plastic Welding with Diode Lasers
It combines the advantages of non-contact welding, without forming fluff or excess melting, with the ability of a measurable setting path.
Laser welding is unique in allowing for high freedom of design in the development of new components and housings.
Diode Lasers with “Top Hat”
Laser technology facilitates non-contact welding with low thermal and mechanical load. This is especially advantageous to plastic housings with built-in electronic components that may be damaged in conventional procedures, such as vibration welding or ultrasonic welding.
Compared with conventional solid state lasers, the diode laser has an advantage because of its wavelength and its “top hat” beam profile without intensity peaks. This avoids local overheating that might damage the welded components.
- Quasi-simultaneous or contour welding
- High process stability
- Low thermal and mechanical load
- Welding with base material strength
- Flexible, non-contact process
- Soft energy coupling due to “top hat” beam profile
