The blog about laser plastic welding
Thanks to their superior properties, such as high temperature and chemical resistance, low weight and dimensional stability, high-performance polymers – such as PPA and PPS – are increasingly replacing assemblies made of metal and conventional engineering plastics. In the automotive industry in particular, this trend is being boosted by the…
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,…
