Ribbons Sefar offers heat- or ultrasonically-slit ribbons. Both slitting techniques ensure an optimally sealed, non-fraying edge quality. Ribbon width ranges from 7 to 2400 mm (heat-slit) or from
4 to 350 mm (ultrasonically-slit).
Stamped discs Fabrics can be provided pre-cut in virtually any configuration by laser cutting, cold stamping or ultrasonic stamping. Cold stamping is the most economical process, laser cutting assures high tolerance pieces with fray-resistant edges and ultrasonically-stamped parts have sealed edges with high tolerance capacity.
Disc diameters range from 6 to 95 mm.
Semi-finished components Filter components can be combined with one or more adhesive layers that enable a cost efficient and fast joining of the filter component to any housing. Stamped discs can also be provided on a dispenser so that the discs can be transported easily, but the disc is free of adhesive as soon as it is rolled off the dispenser.
