eurolaser tested the following RAASCH materials on its laser cutting machines:
Laser Test: RAASCH R3-300 (M5) and RSB 300 (G4)
Laser cutting of filter mats for air purification
Material
The tested filter mats from RAASCH Luftfilter are used for fine and coarse dust filtration in air conditioning and ventilation systems. They are characterised by high dust holding capacity, long service life and low pressure drop. As a cost-effective solution for large air volumes, they meet above-average cleanliness requirements – ideal for offices, public buildings, factories and industrial facilities.
Test setup
The tests were carried out on a eurolaser L-1200 laser cutting machine with a 400 W CO₂ laser and an integrated Conveyor System for automated roll processing. The objective was to achieve tear-resistant, directly sealed cutting edges without scorch marks or discolouration. Intricate contours were also to be cut without distortion. Optional: use of marking modules for product identification.
Result
The RAASCH filter materials were cut without distortion, cleanly and without the need for reworking. No scorch marks or discolouration occurred. Automated roll processing via feeder and Conveyor System enabled a consistently efficient workflow. All requirements were met – laser cutting proved to be the optimal solution for this application.
Advantages
Directly sealed, tear-resistant cutting edges
Clean processing without scorch marks on the material
Distortion-free cutting, even for intricate contours
Automated processing directly from the roll
Optional: application of sewing marks
