The "double air outlet" design means airflow is released in two stages around the ring rather than through a single opening, which allows for more layered, controlled cooling as the film bubble rises past the ring. The "single air lip" refers to the ring's air release edge being one continuous lip rather than a segmented one, keeping the airflow pattern consistent around the full circumference. Being labeled "fully automatic" means the ring is built to run with less manual intervention during production compared to a fully manual adjustment setup, which matters on lines where operators are managing multiple machines at once.
Specific Applications
Mid-to-high output blown film lines — built for the 1000 output range, sitting between smaller low-pressure lines and larger high-pressure setups
Automated or semi-automated production floors — a fit for plants moving toward less manual operator involvement in day-to-day cooling adjustments
Multi-layer and single-layer polyethylene film — supports common film materials including HDPE, LDPE, and LLDPE
Courier bag, aquatic bag, and rubbish bag film production — the same core end products found across most blown film lines using this class of accessory
Lines requiring more consistent airflow control — the double outlet, single-lip structure is suited to plants where operators have noticed thickness inconsistency with a simpler single-outlet ring
Core Functions
1. Two-stage air release — airflow moves through two separate outlet points instead of one, allowing more layered control over how the film bubble is cooled as it rises
2. Continuous single air lip — the release edge runs as one unbroken lip around the ring, keeping the airflow pattern even around the full circumference
3. Automatic operation — designed to run with less manual adjustment needed from operators during production compared to a fully manual wind ring
4. High pressure airflow capability — suited to the stronger air output needed on mid-to-high volume lines
5. Cast aluminum housing — holds its shape under continuous heat and airflow during long production runs
Purchasing Motivation
Buyers moving up from a basic single-outlet wind ring to this type are usually trying to solve one of two things: they need finer control over how the film bubble cools, or they want to reduce how much manual adjustment their operators have to do during a run. The double air outlet setup gives cooling airflow a more layered release pattern than a single-outlet design, which can help with plants that have noticed uneven thickness or streaking with a simpler ring.
The automatic operation side matters most for plants running several machines with a smaller operator team, since less manual adjustment per line frees up staff to manage more of the floor. Because this ring is sized for the 1000 output range, it's a practical step up for plants that have outgrown a lower-output ring but don't need the largest high-pressure setups built for the biggest lines. As with other wind rings in this category, it's produced to custom, non-standard specifications, so buyers get a unit matched to their actual die head diameter rather than adapting a generic part.
