Today, laser plastic-welding is replacing other joining techniques such as gluing and ultrasonic welding in many manufacturing and industrial fields. The modern joining process for plastics is highly flexible and it provides high-strength connections without marking or damaging the work surface. Plastic laser-welding is invaluable when precise control and accuracy is needed to protect vital internal components, and it can be used to successfully weld plastics even when faced with challenging geometries.
Lazer Plastic Welding
The variety of plastics that can be welded robotically is very wide. Robots can weld acrylonitrile-butadiene-styrene, polyvinyl chloride, acrylic, polycarbonate, polyethylene, fiberglass and carbon reinforced plastics, along with fluorocarbons.
In the automotive sector, robotic plastic welding is used on instrument panels, bumpers, fuel tanks, manifolds, fuel filters, valves and sensors, anti-lock braking system components, fuel injectors, parts of electronic ignitions.
The consumer product area has a considerable amount of robotic plastic welding, including plastic watches, toys, toothpaste tubes, video and audio tape cassettes, ink-jet cartridges, computer floppy disks, dental devices, computer disk drives, and audio-video equipment.
The electronics industry uses robot-based plastic welding to form toggle switches, connectors, terminal blocks, switches, printed circuit boards, stencils and screens, and for other sensitive devices.Other uses for robotic plastic welding includes items in the medical, packaging, textile, and optical industries.
With many potential uses and reduced cost barriers, the use of plastic laser welding will increase gradually in the industries. The process allows for unprecedented flexibility in precision and materials, making it ideal for innovative welding applications.
