LASER MICROPERFORATING UNIT MODEL LO-S 40 This machine is designed to make MICRO HOLES or PRECUTS through LASER SOURCE on MOVING FILMS of various materials and thicknesses . This machine has to be integrated into existing machinery such as extruders, bag machines, slitters, printing machines, welding machines, etc. The LO-S 40 LASER model guarantees perfect micro holes even on multi-layered, mono or bi-oriented materials. It is ideal for delicate processes such as MICRO-PERFORATION and SCORING of plastic film fo r 4TH AND 5TH RANGE PRODUCTS, FOR MAP AND EMAP PACKS. With the holes made by this machine, it is possible to control air exchange with the outside and, more generally, to CONTROL PERMEABILITY, thus increasing the SHELF LIFE of all fresh products. How it works The moving film, kept in perfect tension by the idle rollers, arrives at the unit and is perforated or pre-cut by the laser equipment by EMITTING BEAMS OF LIGHT with a predetermined INFRARED FREQUENCY. These beams are "combed" and expanded by a BEAM EXPANDER. The light beam direction is then controlled and moved through the use of motorised mirrors. At the end, there is a FOCUSING LENS that concentrates the emitted light beam onto a circumscribed surface of the moving film. Micro perforation is made by SUBLIMATING the material through the heat of the laser beam. Spark Machinery S.r.l.

TECHNICAL DESCRIPTION The ACTIVATION and ADJUSTMENT of the LO-S 40 is entrusted to our software with predisposition 4.0. From the electrical control panel, via touch screen, the operator manages all the operations inherent to the device such as the adjustment of the laser pulses, the diameter and position of the holes. The electronics is equipped with a PC through which the operator can control each scanning head and decide the perforation pattern. Using the laser unit, you can decide either to MAKE HOLES or WEAKEN THE MATERIAL in depth, reducing the thickness of the film, without perforating...
