Laser cutting of filters

Filter production: discover the different production techniques

Raytech’s filter activities can be divided into three segments:

  1. Filter laser cutting from metal sheet
  2. Processing existing filter material
  3. Building filters layer-by-layer (3D printing)


Filters from sheet material

Process based on metal sheet that is purchased on a roll or as a flat sheet. Once the material has been placed in the machine, the entire filter pattern is cut out. (Image at the top of the page is an example of fully laser-cut filter discs, started with cutting the holes and then the contour).

This method is often used for filter parts where the shape or hole pattern cannot be obtained using filter cloth or mesh.

Using micro laser cutting, holes can be cut with a diameter smaller than 50 µm. This makes it possible to produce high precision micro filtration parts.

As for the speed of the laser cutting process; depending on the size of the holes and the material thickness, between 1 and 15 holes per second can be made.

In thin material (foils) there’s also the possibility to make filters by means of laser drilling. Hundreds of holes per second can be made by means of laser drilling / laser perforation. More info: laser drilling


Cutting filter cloths and metal mesh to size

In addition to laser cutting of filters from sheet material, it is also possible to process existing filter material. Laser cutting allows to cut filter material to size very accurately and to cut extra shapes such as holes and slots. Textile filter cloth, metal mesh, knitted material … are just a few examples of materials that can be processed with laser.

Processing existing filter material with laser:

  • Extremely high cutting speeds
    • ‘High speed’ laser machines combined with a roll-off mechanism to process material from coil.
  • Burr-free – free from fraying
  • No contamination
    • Correct clamping of the material is essential in order not to get contamination on the filter material.
  • High precision
  • No reflection on the bottom of the material

3D printing of filter components

3D printing of filter parts is a striking innovation in the filtration industry. Building a component layer-by-layer makes it possible to create unique internal channels. These channels provide unseen possibilities for the distribution and filtration of liquids.
