MICRO: High speed cold & hot needle perforation and spare parts
MOD. SM-CMM
The cold needle perforation is a mechanical perforation where the material is only pushed aside and not melted by heating. This generally results in the hole partially re-closing after perforation, which offers some advantages when trying to permit only one-way passage of a liquid or solid through the hole. The back-up pressure roller could be in natural fibre (brush) or rubber according to the material to be processed.
The Mod. SM-CMM is suitable for high speed and or high density of pins, like of example for aluminium or foam material. It could be installed on extruder, slitters, bag making machines, printing machines and so on. The max material width is 2500mm and the max speed is 250 meters per minute.
