Import Air Ring With Dual Lip Rotary Type — Buy in Bulk from Supplier in Taiwan

Horng textile Industrial Co., Ltd. produces a dual lip rotary type air ring engineered for blown film extrusion lines where precise cooling airflow governs bubble stability and gauge uniformity. The dual lip geometry creates two discrete annular air jets that impinge on the extruded tube at staggered heights, improving heat transfer coefficients compared with single-lip designs. Cast aluminium alloy construction, typically A356-T6 or AC4CH grade, keeps rotational mass low while resisting corrosion from moisture in the cooling air stream. The rotary design allows the air ring body to spin at line speed, eliminating stationary-to-moving air seals that cause film drag marks.

The dual lip configuration reduces turbulence at the frost line boundary, a critical parameter for LLDPE and HDPE films where neck height control determines mechanical properties. Lip gap settings are typically adjustable between 1.0 mm and 2.5 mm, with standard diameters ranging from 200 mm to 800 mm to match die sizes from 50 mm to 250 mm. Air inlet connections conform to common blower hose diameters, and the internal plenum is designed for uniform circumential pressure distribution. Surface finish on the lip lands is typically Ra 3.2 or finer to prevent film scratch, and hard anodising to 25 microns is standard practice for wear resistance in abrasive mineral-filled formulations.

Buyers are primarily blown film converters, packaging material manufacturers, and extrusion equipment rebuilders who need to upgrade cooling capacity for faster line speeds or thinner gauge targets. The air ring is a wear-susceptible consumable in continuous operation, so spares strategy matters. Trade specifics such as MOQ, unit price, and delivery schedule are not present in the source data; buyers should confirm these directly with Horng textile Industrial Co., Ltd., along with whether the quoted diameter range includes custom sizing for non-standard dies.

Horng textile Industrial Co., Ltd. is based at No.79, Heping East Road in Yongkang District, Tainan 71042, Taiwan. The supplier holds an imported tier classification and a harbor trust tier, with zero percent response rate and no recorded average response hours. These profile signals indicate limited active engagement through the platform channel, so buyers should plan to initiate contact directly and verify current production status and export readiness independently.

The company operates within Taiwan's established precision machinery supply base, where aluminium casting and CNC finishing capabilities support plastic machinery component production. No factory size, annual revenue, specific quality certifications, or client reference lists are present in the source. Buyers should request current ISO 9001 registration status, material test certificates for the cast alloy, and dimensional inspection reports for concentricity and lip gap uniformity before committing to volume orders.
