Syncro

AUTO, is the new SYNCRO PATENT PENDING automatic air ring designed for high efficiency and high output. Elevators lift up the automatic upper four lip air ring almost doubling the line throughput while improving physical proprieties of the film as per tear, haze, elongation and especially dart drop.

Wide range of application

When is raised to the upper position where the bubble expansion is greater, it provides efficient cooling over a larger surface. Simple start-up and die cleaning are added benefits of the vertical adjustment. AUTO provides segmented airflow to localized areas around the blown film bubble through the air ring while stabilizing the film exit due to the forth special downward lip. This automatic thickness improvement system offers simplicity and state-of-the-art visualization giving the highest operational reliability. The system effectively increases the low areas in the film to improve quality and yield.
