FAQs
What is laser plastic welding and how does it work?
Laser plastic welding uses a focused laser beam to bond thermoplastic materials. One layer must be transmissive to the laser, while the other absorbs the energy. This causes localised melting and bonding upon cooling, resulting in a durable, precise joint.
How does laser plastic welding compare to traditional welding techniques?
Unlike ultrasonic or vibration welding, laser plastic welding provides minimal material stress, cleaner joints, and high repeatability. It requires less post-processing and supports more complex component geometries.
What plastics are suitable for laser welding?
Materials such as ABS, polycarbonate, polyethylene, and nylon are commonly used. With the right additives or coatings, even more thermoplastics can be adapted to suit this technology.
What types of laser plastic welding methods are used?
Methods include contour welding, simultaneous welding, quasi-simultaneous welding, and scan welding. Each method is selected based on the complexity and requirements of the component being manufactured.
Is laser plastic welding suitable for medical devices?
Yes, it is ideal for medical devices due to its precision and non-contact process. It ensures clean joints free of contamination and meets stringent medical manufacturing regulations.
