Metal Drilling | Foil Processing

We offer metal drilling services – irregular shape, smooth sidewalls, minimal heat-affected zone.

When other lasers or mechanical processing methods do not meet technical requirements, femtosecond lasers are unique for their processing due to minimized heat effects while keeping sub-micron feature size.

Laser drilling of metal alloys brings high quality and precision for many applications – diverse filters, mesh filters, FCO melt filtration, aerosol generation, inhalation applications, drug delivery systems, functional surfaces, fuel delivery systems, and many more.

Features

No melting and thermal impact in peripheries
Holes diameter from micrometer range micrometer to centimeter range
Precise control of taper angle
Variable geometry of holes
Different processing parameters might be developed upon request.
