Laser welding machines in the microfluidics segment

Microfluidics technology requires highly precise, often parallel joint lines stretching for several meters on a small component. Microfluidics and the diagnostic equipment sector also demand resolutions which can only be achieved using laser technology. And in all cases: An absolute priority is ensuring that no foreign bodies or additives can penetrate the channels.

Seam widths in the micrometer range can now be produced using fiber lasers or fiber-coupled diode lasers without restricting the flexibility of the welding seam geometry or the strength of the joins.

The convincing benefits of laser plastic welding for microfluidics: 

• joint lines in the micrometer range
• hygienic energy input
• no foreign bodies or additives
• traceability / end-to-end process monitoring
• extremely short cycle times
• new design options
