High-precision laser welding of transparent plastics without additives

nanosystec GmbH is expanding its existing portfolio of laser welding systems by VersaWeld-TLPW (Transparent Laser Plastic Welding). It welds transparent plastics without additives, with high-strength substance-to-subtance bonds, highly precise in 3D.

Lab-on-a-chip systems offer the functionality of a laboratory on a credit card-sized piece made of transparent plastic. Thus far, high manfacturing costs have put a brake on the wide use of this technique. The new VersaWeld-TLPW offers an important, cost-effective manufacturing step for such lab-on-a-chip systems on an industrial scale while the absence of additives preserves biocompatibility.

The new system can process any thermoplastic polymer. The fiber laser used operates in the near infrared. Here, these polymers are semi-transparent, hence they absorb enough laser power to ensure a secure weld. The heart of VersaWeld-TLPW is a fiber laser, combined with exceedingly accurate positioning systems, allowing high-precision manufacturing even of complex geometries. Thanks to the high beam quality of the fiber laser and thus to a very small focal spot, almost any degree of fine joining seams are possible.

The system can easily be integrated into existing production lines. A unique tracking of joined workpieces e.g. by means of scanners and SQL database connection is possible without any problems.
