Spiral Duct Machine

The Spiral Duct Machine HCY-2000 is designed for efficient production of round spiral ducts used in HVAC ventilation, air conditioning, industrial ventilation, and related ductwork applications. The machine forms metal strips into a continuous spiral duct through a controlled rolling and locking process, producing round ducts with consistent dimensions and reliable seam quality.

With a duct diameter range of 80–2000 mm and a production speed of up to 38 m/min, the HCY-2000 is suitable for both standard duct fabrication and high-volume HVAC production. Its practical forming structure, automatic cutting system, and hydraulic and pneumatic power configuration help streamline the complete forming process.

Efficient Spiral Duct Forming

The HCY-2000 uses a roller-based forming process to continuously shape metal strips into spiral ducts. During production, the material passes through the forming section and is shaped into a round spiral profile before the edges are securely locked.

The forming system is designed to maintain stable pipe dimensions throughout production. This is important for HVAC duct manufacturers that need consistent duct diameters and reliable connection performance during subsequent installation.

The machine can produce spiral ducts in a wide range of diameters, making it suitable for ventilation projects with different airflow requirements. Its adjustable production speed also allows operators to select an appropriate working rate according to material thickness, duct size, and production conditions.

Wide Material and Thickness Range

The Spiral Duct Machine HCY-2000 is designed to process different sheet materials commonly used in HVAC duct manufacturing.

According to the supplied specifications, the machine supports:

• Galvanized steel: 0.4–1.3 mm

• Stainless steel: 0.4–0.8 mm

• Material width: 137 mm

• Duct diameter: 80–2000 mm

This material flexibility allows manufacturers to produce spiral ducts for different project requirements while using the same forming platform.

For customers working with different duct sizes or materials, the machine can be adjusted to match specific production requirements. This makes it practical for HVAC duct factories, sheet metal workshops, ventilation contractors, and ductwork manufacturers.

Stable Forming and Sealing

A stable locking seam is essential for maintaining the structural integrity and air-tightness of a spiral duct. The HCY-2000 forms the duct through a controlled spiral locking process, helping produce consistent seams along the finished pipe.

The forming head mould is manufactured from steel, while an aluminum alloy casting option is available according to production requirements. The mould structure is designed to support stable forming and long-term operation.

The external locking configuration is suitable for standard spiral duct production, while different seam arrangements can be considered according to specific requirements.

Automatic Cutting System

The HCY-2000 is equipped with a patented flying slitter cutting system. Unlike a basic stationary cutting process, the flying cutting design allows the duct to be cut during continuous production, helping reduce unnecessary production interruptions.

This configuration is particularly useful for manufacturers producing spiral ducts in different lengths. By coordinating forming and cutting operations, the machine can improve workflow continuity and reduce manual intervention.

The cutting and material-turning functions use pneumatic power, while hydraulic power is applied to material discharge and roller compression. This combination provides a practical power configuration for the machine's main working processes.

High Production Speed

Production efficiency is an important consideration for HVAC duct manufacturers. The HCY-2000 offers a production speed of approximately 1–38 m/min, allowing users to adjust the operating speed according to material, duct diameter, and actual production requirements.

The relatively wide diameter range and adjustable production speed make the machine suitable for both standard orders and larger-volume duct manufacturing.

For workshops handling multiple duct specifications, the machine can reduce the need to frequently change between different forming machines, helping simplify equipment configuration and production planning.

Compact and Practical Machine Design

Despite its ability to produce ducts up to 2000 mm in diameter, the HCY-2000 is designed as an integrated production machine with a practical footprint.

The supplied specifications are:

The actual configuration can be confirmed according to the customer's material, voltage, duct specifications, and production requirements.

Designed for HVAC and Ventilation Applications

Spiral ducts are widely used in HVAC and ventilation systems because their round structure provides practical airflow characteristics and efficient installation options. The HCY-2000 is therefore suitable for manufacturers producing ductwork for commercial buildings, factories, warehouses, workshops, and other ventilation projects.

Typical applications include:

• HVAC duct manufacturing

• Central air conditioning systems

• Industrial ventilation

• Workshop ventilation

• Warehouse ventilation

• Commercial building ventilation

• Dust and air exhaust systems

• Customized spiral duct production

For manufacturers supplying different projects, the machine's wide diameter range provides flexibility for producing both smaller and larger spiral ducts.

Manufacturer Support and After-Sales Service

HCY provides support throughout machine selection, installation, operation, and after-sales service. Customers receive a detailed operation manual, while technical support can also be provided through factory training or on-site engineering assistance.

For customers who are new to spiral duct production, operator training helps ensure that the machine is correctly installed and adjusted before entering regular production. Telephone and email support are also available for technical questions and troubleshooting.

The machine is supplied with a 1-year warranty, and quality-related damaged parts can be replaced according to the warranty terms. Key components use high-strength steel with special treatment designed to improve wear resistance and corrosion resistance.

For customers requiring fast delivery, the supplier also states that machines are available from stock, subject to actual inventory confirmation.
