Thermal Welding

Cemas

According to the state of the art, there are numerous thermal welding processes for joining thermoplastic components. Every welding processes, be it heated tool, infrared or laser, offers process-specific advantages and disadvantages. Selecting a process requires expert knowledge of the different welding processes and the material used. Cemas Elettra S.r.l, Carmagnola, Italy, bundles this know how with a wide product portfolio. The company has developed a multi-fiber laser welding machine for the simultaneous welding option. Since the development work concentrated on a tail light, particular attention was paid to the optical requirements of the weld seam. In simultaneous welding, the weld seam can be simultaneously heated and joined, so that constant seam thicknesses can be achieved. This permits short machine cycle times and welds of high optical quality.

Besides the continuous enhancement of the vibration welding machines with 240 Hz and 100 Hz, it has included the combination of infrared preheating and vibration welding in its portfolio. In general, formation of particles in the weld zone is unavoidable in vibration welding because of the friction movement. Particularly in the case of fluid carrying components, this can present considerable challenges. The coupling of conventional vibration welding with an infrared preheating unit reduces the particle formation in the weld and leads to optically attractive weld seams.

Moreover, Cemas Elettra offers various types of standard machine in the field of ultrasound welding, which are based on a modular concept, and puts together special machines according to customer’s needs.
