- The blog about laser welding of plastics

On these pages everything is about laser welding of plastics. A process with almost infinite application possibilities. Clean, energy-saving, flexible and therefore a future-proof process. In addition, it is simple and uncomplicated to use.

Quality assurance IV – Process control by pyrometry

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…

Thermoplastics for laser welding – Part 3

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…

Thermoplastics for laser welding – Part 2

In order to adapt plastics as ideally as possible to their field of application, various additives are added to them. ADDITIVES – They are added to the polymer in small quantities and thus cause a change in the corresponding properties. The additives, which are usually very different from the base…

Laser welding of thermoplastic elastomers

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 the macromolecules decomposing. As a result, the processing methods of…

Thermoplastics for laser welding – Part 1

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 and thermal compatibility of the two materials. In addition, the…
