Extruder Machine Air Ring is a critical component of blown film extrusion systems used in the manufacturing of plastic films. The air ring is designed to create a uniform flow of air around the emerging film to help cool and set the film as it exits the die. Extruder Machine Air Ring is typically made of high-density plastic and is mounted at the base of the extrusion die. It has a series of holes or slots that release a controlled flow of cool air around the film as it emerges from the die. The shape and size of the air ring can vary depending on the specific requirements of the film being produced.
