AIPC – namely Automatic Injection Pressure Control – is the latest innovation in the PET drying systems introduced by Piovan. It synchronizes the drying system to the preform injection molding machine and, by reading the injection pressure in real time, can stabilize it to the desired value. Keeping the injection pressure at the highest level of constancy brings the quality of PET preforms production to excellence.
The new algorithm specifically developed for the AIPC, can constantly adjust airflow, temperature and dew-point of the process air, so that the injection pressure is kept at the highest possible level of constancy. This is particularly valuable today, as the new preform formats require thinner walls and therefore controlled conditions of moisture and injection pressure.
