The blog about laser plastic welding
Laser transmission welding of plastics is dependent on a laser-transparent and laser-absorbing joining partner, which are connected in an overlap weld. Usually, the necessary optical properties are adjusted by additives. In the simplest case, carbon black is added to the absorbing component, while the transparent part remains unfilled. What works…
In simultaneous welding, the entire weld seam is heated and melted at the same time (i.e. simultaneously) by one or more beam sources. The arrangement of the beam sources or the beam shaping by means of suitable optical elements must be carried out in such a way that the line…
In so-called quasi-simultaneous welding, the weld seam is repeatedly scanned at high speed with a focused laser beam. The feed rates are usually above 300mm/s up to several meters per second. All areas of the weld seam are heated and melted almost simultaneously (i.e. quasi-simultaneously). Due to the simultaneous melting…
A special form of contour welding is the variant for processing radially symmetrical assemblies. An essential difference between this special form and the other process variants of laser plastic welding is the application of joining pressure in the joining zone. Due to the radially symmetrical structure of the joining assembly…
