Blown film extruder

The blown film extruder from Horng Tair Industrial Co., Ltd. is a Taiwanese-manufactured machine designed for continuous production of plastic film through the blown film process, where molten polymer is extruded through a circular die and inflated into a tubular bubble. The machine features a screw and barrel system engineered for consistent material conveyance and controlled melting, with adjustable barrel heaters and integrated cooling fan for thermal management across different resin types. Based in Tainan, Taiwan, Horng Tair Industrial positions this equipment for packaging, agricultural, and automotive film applications where output consistency and versatility in material processing are valued.

The screw and barrel assembly represents the core processing unit, with the screw geometry, compression ratio, and L/D ratio determining melting efficiency, mixing quality, and output rate for materials ranging from low-density polyethylene to linear low-density polyethylene and metallocene blends. Barrel heaters with zone control allow temperature profiling along the extrusion path, compensating for shear heat generation and optimising viscosity for die entry. The cooling fan system manages bubble stability and frost line height, critical parameters that affect film gauge uniformity and mechanical properties. Hopper design and accessibility for loading and cleaning are practical considerations for operations with frequent material changeovers.

Buyers of this equipment typically include flexible packaging converters producing bags, wraps, and laminates, agricultural film manufacturers supplying greenhouse and mulch films, and automotive parts suppliers requiring protective films and surface protection materials. The machine is described as adaptable to both small-scale and large-scale production, though actual output rates in kilograms per hour or metres per minute are not specified in the source data and should be requested from Horng Tair Industrial directly. Prospective purchasers should also clarify available die diameters, take-off unit configurations, winder specifications, and whether the quoted configuration includes air ring, bubble cage, and corona treatment options.

Horng Tair Industrial Co., Ltd. is headquartered at No.79, Heping East Road, Yongkang District, Tainan 71042, Taiwan, placing it within one of Taiwan's established industrial corridors with access to southern Taiwan's manufacturing ecosystem and Kaohsiung port facilities. The company holds an imported supplier tier and harbor trust designation on the marketplace, though its response rate is recorded at 0.00 percent with zero average response hours, indicating no platform-mediated communication history is available. Buyers should initiate direct contact and establish communication protocols, bearing in mind that Taiwanese industrial suppliers often prefer direct email or telephone engagement for technical machinery discussions.

The source description characterises Horng Tair Industrial as offering customised configurations with barrel covers, barrel heaters, and cooling fan options, suggesting a degree of modular flexibility in their equipment builds. However, no information is provided regarding company founding date, workforce size, annual production volume, R&D capabilities, quality certification scope, or installed machine base. Buyers should request details of their quality management system, whether they hold ISO 9001 or CE marking for machinery, and their experience with export markets and after-sales support infrastructure. The Tainan location may facilitate technical visits for serious purchasers evaluating manufacturing capabilities before commitment.
