Laser beam welding is a welding technique used to join plastic pieces through the use of a laser. Due to the small amount of molten material and the short, controllable melting period, some materials can be combined, which otherwise could not be welded.
The advantage of this welding technology is that the weld is created inside the structural component, without releasing any particles of any kind. This creates an esthetic and almost invisible welding seam. Moreover, welding of complex shapes is possible, with a minimal mechanical
Vibration welding is a commercially used process that can be applied to almost any thermoplastic material. In vibration welding, two plastic parts are in frictional contact with each other with a certain frequency, amplitude and pressure.
This technology offers a large number of advantages such as: cost-effective process, short cycle times, simple equipment, virtually no smoke, fume or inclusions during welding phase. Vibration welding is generally used on large parts, but also smaller components can be welded economically, by designing multiple cavity tools. Learn more
Plastic components can be welded together by using Infrared radiation, especially in case of challenging materials and large part assembly with high strength and hermetic requirements. Infrared heat is transferred without contact, and the heat input is fast, specific and energy-efficient.
This technology offers a large number of advantages: thanks to contactless heating of the plastic, infrared welding meets strict requirements regarding the absence of particles after the joining process; moreover, this technology is
The ultrasonic welding process is based on a conversion of friction and vibration energy into heat. Using a welding tool called “sonotrode”, the high-frequency vibrations generated by the ultrasonic system, are transferred to the components: the ultrasonic energy melts the point contact between the two parts, creating a joint.
Ultrasonic welding equipment can be easily customized to fit the exact specifications of the product to be welded. The benefits of ultrasonic welding are that it is much faster than conventional adhesives or solvents. The drying time is very quick, and the pieces do not need to remain in a jig for long periods of time waiting for the joint to dry or cure. Learn more
