Prototypes and small series manufacturing:
  • Manufacturing of prototypes
  • Pre-series and small series production


Maturation of a new process
Laser welding is now an established technique for welding thermoplastics. New applications are constantly being added, which add to the advantages it has over traditional joining techniques. Laser technology also often offers a solution where conventional systems fail or can only deliver unsatisfactory results. You can benefit from our know-how by having us test your applica-tions.

Nothing but advantages
  • Contactless, flexible joining technique
  • Minimum thermal load on the parts to be welded
  • Simple geometry for the seam
  • No particle release
  • Vibration-free processing
  • Visually perfectly welded seam
  • Highly accurate
  • Very resilient
  • No wear and tear to tools

Suitable materials

Almost all thermoplastic plastics and thermoplastic elastomers, including ABS, PA, PC, PP, PMMA, PS, PBT and fiberglass reinforced plastic types, can be welded with laser beam. The welding seam strength is comparable with that of the base material. 

Transparent plastic can be welded to dark plastics which have preferably been colored with soot. Special pigments allow welding dark,dark and transparent/transparent combinations, as well as colored plastics.
