Today, it is widely believed that laser welding of plastics was invented around the turn of the millennium. However, old patents and patent applications in particular show that the technology was considered and also used much earlier. For example, Mobil Oil Corporation applied for patent US 3,560,261 in 1964 and…
Radial laser welding of radially symmetrical assemblies, such as connectors and tubes, is of particular importance. Unlike the other process variants, no additional clamping force is usually applied due to the joining geometry. Nevertheless, to ensure good thermal contact and sufficient joining pressure in the interface, the components should have…
Advanced Quasi-Simultaneous Welding, or AQW for short, is a new, patented process. It uses the advantages of conventional laser welding and combines this with the advantages of the EvoClear process for clear-clear welding. As a result, a significant reduction in welding time and improved weld quality can be achieved. The…
The possibilities for monitoring the joining process in laser plastic welding are wide-ranging. State of the art is primarily indirect methods which do not assess the weld seam itself, but which allow conclusions about the expected seam quality on the basis of various monitoring variables and inputs. In the case…
In most cases, plastics are processed into an end product in a colored state. In the case of consumer goods or on visible components in the automotive sector, for example, aesthetic aspects and specifications must be taken into account. However, functional colorations such as signal colors are also required in…
