LPKF PrecisionWeld 3000

Precision welding of microfluidics and clear-clear joints

You are here: Products > Stand-alone Systems > LPKF PrecisionWeld 3000
The new high precision laser welding system LPKF PrecisionWeld 3000 allows new layout options for microfluidic components. It creates a precise joint between upper and lower part. These fine weld seams have a width of only 100 µm. The positioning repeatability of 30 µm is highlighted by the name of the system.

The LPKF PrecisionWeld surpasses existing technologies like transmission laser welding (contour- and quasisimultaneous welding) with the addition of the new clear-clear method LPKF ClearJoining. Clear-Clear welding of two laser transparent partners without additives.

  • Compact system, can be placed on rollers
  • Integrated vision system for identifying fiducial marks
  • Laser scanner and processing table
