The blog about laser plastic welding
Thermoplastic elastomers (TPE) are a group of plastics that exhibit rubber-elastic properties. Unlike the conventional, chemically wide-meshed crosslinked elastomers, their polymer chains are embedded in a thermoplastic matrix. The physical crosslinking points dissolve reversibly under the influence of heat without…
Due to their molecular structure and the associated thermal properties, thermoplastics have a special position among polymer materials. They are both meltable and plastically formable. This behavior enables the welding of two thermoplastic polymers. However, this requires a minimum chemical…
A wide range of options is available for ensuring quality and monitoring the joining process during laser plastic welding. Even before welding, necessary part properties, such as laser transmission, can be easily and reliably checked (see also article Quality assurance…
In order to keep defect costs in production low, it is useful to detect defects from pre-production before the welding process so that the corresponding components can be sorted out. In laser welding, by far the most frequent cause of…
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…
