Laser welding of a fluid manifold (Medical / Filtration)

Producing leak-tight fluid circuits for medical and filtration applications by joining injection-moulded parts without adhesive. The aim is to enable the design of complex geometries while ensuring reliable and clean assemblies.

Implementation of a mid-infrared laser welding process enabling transparent polymer parts to be joined without specific additives or pigments. Development of the process and tooling to ensure joining accuracy and continuity of the fluid channels.

Creating complex fluid channel networks while ensuring perfectly leak-tight assemblies and precise control of weld quality on delicate internal geometries.

The process produces perfectly leak-tight fluid circuits with great freedom of geometric design. Joining accuracy is optimised and weld quality meets the strict requirements of the medical sector.
