The blog about laser plastic welding
Laser welding of plastics is a very robust and reliable process. The causes of defective welds are mostly found in pre-processes along the value chain. Already in the first step, the compounding, the material components and thus the important optical properties are determined. Although the usual fluctuations in this step…
Today, the laser is an established tool in many areas of production. Due to its high precision, the locally well-dosable energy input and last but not least its cleanliness, this tool has secured itself a firm place in production. Laser plastic welding in particular is particle-free, making it a key…
The following criteria are specifically relevant for the individual process variants and must be taken into account accordingly when it comes to the design layout of the joining zone. CONTOUR WELDING-TOLERANCES – As no relative movement of the joining partners to each other can take place in a contour welding…
The laser welding of plastics is dependent on a laser-transparent and laser-absorbing joining partner, which are connected in an overlap weld. While the absorbing properties are usually robustly adjusted by additives and other influences play a minor role, the laser transmission reacts sensitively to various factors. These are, for example,…
An essential component for a robust process is the design of the joining zone. Basically, a distinction can be made between process-independent and process-dependent criteria. The following criteria and information are generally valid for all process variants. MATERIAL THICKNESS – Depending on the material used for the laser-transparent joining partner,…
