Hot microperforating unit HN100

for plastic films

This equipment is designed to make "hot" micro holes on moving film of various materials and thicknesses and is to be inserted as a host unit in film processing lines, such as slitters, extruders, printing and welding machines. The HN100 is a motorized unit with an automatic synchronization system that ensures perfect micro holes on a variety of materials; ideal for delicate processing on shrinkable and non-woven materials; for processing requiring holes with very high needle density per cm²; and for processing mono- or bi-oriented materials. The HN100 is an electrically heated hot needle micro-perforator. The running film arrives at the machine and passes through the heated motorized needle roller and the counter roller, which approach each other and perforate the material. The rollers are approached through the pneumatic system, and the perforation adjustment is implemented by two micrometer screws. OPERATION CONTROL of the HN100 is entrusted to our software designed for 4.0 integration from the electrical control panel. 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 roller to the needle shaft is enabled only at optimum film running speed and temperature, to ensure perfect holes and to prevent, due to wrong temperature or slow film running, material melting on the needles.
