Hot microperforating unit HN200

This system is designed to make "hot" micro holes on moving films of various materials and thicknesses and is to be installed as a host unit in film transport lines, such as slitters, extruders, printing and welding machines. The HN 200 guarantees perfect micro holes on mono- or bi-oriented materials and even with low heat input; it is ideal for delicate processing on shrinkable material or with very high needle density per cm2. The HN200 is an electrically heated needle microperforator. The running film arrives at the device and is perforated by the motorized needle shaft that is approached by the contrast roller designed to support the material. The micro-perforation is achieved by melting and perforating the material, caused by the needles fixed on the interchangeable bronze sleeves. The needle sleeves are mounted on the needle shaft placed inside an insulated chamber and brought to an adequate temperature by the group of infrared lamps. The operation of the HN200 is entrusted to the electrical control panel with our software designed for 4.0 integration. The operator via touch screen manages all operations inherent to the device such as temperature control, control of heating elements, emergency activation and needle shaft rotation. When the device is paused, the needle shaft rotates slowly to maintain a uniform heating or cooling temperature to avoid any damage. In "automatic function," the approach of the counter roll to the needle shaft is enabled only at optimal speed and temperature, to ensure perfect holes and to avoid melting of the material on the needles due to incorrect parameters.
