Cooling ring

For blown film extrusion lines Syncro proposes the Flyer cooling ring with automatic profile control. It is mounted above the extrusion head and can be adjusted in height above the die thanks to three electric elevators. The lifting system facilitates head cleaning and speeds up the plant start-up.
The device features four cooling flows and dual top stabilizer. The special position of the lips as well as the shape of the inserts make it possible to treat a wide portion of the bubble, improving the exchange surface in comparison with a traditional ring. The throughput results doubled in comparison with a traditional dual lip ring and exceeds 2 kg/h for 1 mm of die diameter. This cooling ring allows inflation ratios higher than the traditional ones and gives the film better physical-mechanical characteristics thanks to the better balance between longitudinal and crosswise elongations.
