Future-oriented and economical cutting of filter materials by laser

T. Meyer, eurolaser GmbH, Germany

Nowadays, filtering is becoming an increasingly important aspect as well as the fact that many companies have increasingly been putting major focus on the topic of 'environment'. Modern filter media are used for the separation of environmentally hazardous process by-products. Often, the deposited material is also the desired product. Therefore, the filter media used - such as felts, nonwovens, paper and other fabrics - must be designed accordingly. The cutting of such fabrics with conventional methods, such as knife or punch, is time- consuming as well as dust- and cost-intensive, as the cutting edges are often subject to fraying and, therefore, waste must be taken into account from the outset. The tools are subject to wear and must be replaced, which is also costly and time-consuming. In addition, the flexibility is often limited due to non-selectable contours.

Here, industrial laser cutting solutions offer many advantages. An important aspect of the CO2 laser is the non-contact processing. There is no distortion during cutting which results in more precise cutting results and less waste. No clamping of the material is required; thus, material crushing is eliminated, process planning approaches zero and the material can be fully exploited to the brim. Another advantage of the ‘laser’ tool represents the fact that, compared to knife or punching tools, there is not any tool wear. The cutting remains of a continuously good quality, as no sharpening is necessary. Costs and downtime due to tool changes are also eliminated. eurolaser has specialised in the development and design of laser processing systems for non-metallic materials consisting of a modular construction. This enables...
