Turret Punch Press and Flanging Machine Solution for High-Volume Ventilation Duct Production

An HVAC duct manufacturer in Russia needed a stable and efficient sheet metal fabrication line for large-volume ventilation duct production. The customer’s products include rectangular ducts, ventilation panels, air conditioning duct sections, flange structures, mounting plates, and sheet metal components used in HVAC and industrial ventilation projects.

To support the customer’s production upgrade, STON CNC provided a turnkey HVAC duct fabrication line integrating a Turret Punch Press and a Flanging Machine. The solution was customized for high-volume duct production and reliable operation under demanding workshop and regional climate conditions.

Contexte du projet

HVAC duct manufacturing requires both production speed and assembly accuracy. Duct panels often include dense perforation patterns, mounting holes, edge notches, flange structures, and long sheet metal sections that must fit together tightly during installation.

For manufacturers serving commercial buildings, industrial plants, warehouses, public facilities, and ventilation engineering projects, production bottlenecks usually appear in three areas:

• Large-format duct panels are difficult to handle manually.
• Dense holes and mounting patterns require stable punching accuracy.
• Flange forming must remain consistent to support airtight duct assembly.
• Manual processing increases cycle time and labor intensity.
• Harsh workshop conditions require stable equipment performance.
• High-volume duct orders require a continuous and scalable production workflow.

STON’s HVAC solution page also highlights that ventilation and air conditioning manufacturers often need precise forming, dense perforation, large-format panel handling, and consistent flange tolerances for airtight assembly.

STON CNC Solution

STON designed a complete HVAC duct fabrication workflow based on turret punching + flange forming.

The turret punch press processes ventilation holes, mounting patterns, notches, and edge features on duct panels with high efficiency. This helps the customer complete repeated hole patterns and functional openings before forming.

The flanging machine then forms duct edges and flange structures required for connection, sealing, and assembly. For HVAC duct production, stable flange forming is critical because bending variation directly affects duct connection quality, air leakage control, and installation efficiency.

This turnkey configuration helped the customer build a more efficient production process for:

• HVAC duct panels
• Rectangular duct sections
• Ventilation components
• Air conditioning duct parts
• Industrial exhaust duct panels
• Flanged duct structures
• Mounting and connection plates
• Large-format sheet metal duct components

La ligne modernisée a permis au client de :

• Improve production efficiency for high-volume HVAC duct panels.
• Improve punching accuracy for ventilation holes and mounting patterns.
• Maintain more consistent flange forming for duct assembly.
• Reduce manual sheet handling and forming variation.
• Support large-format duct panel processing.
• Improve production stability in demanding workshop conditions.
• Build a stronger foundation for future HVAC sheet metal automation.

Why This Solution Fits HVAC Duct Manufacturing

HVAC duct production requires fast punching, stable forming, and consistent assembly dimensions. Duct panels often need repeated holes, long edges, flange structures, and airtight connection surfaces.

A turret punch press is suitable for processing repeated duct panel features, while a flanging machine helps form the edge structures required for duct connection and sealing. Together, they create a practical production line for manufacturers handling large-volume ventilation duct orders.

For HVAC and ventilation equipment manufacturers, this solution can reduce manual processing, improve part consistency, and support continuous production for commercial and industrial duct projects.

Valeur du projet

This Russia project shows how STON CNC supports HVAC duct manufacturers with turnkey sheet metal fabrication equipment, not just single-machine supply.

By combining turret punching, flange forming, process planning, and equipment customization, STON helped the customer build a production line suited for high-volume duct fabrication and harsh operating conditions.

For manufacturers producing ventilation ducts, HVAC panels, air conditioning duct sections, industrial exhaust ductwork, and flanged sheet metal components, STON CNC can provide customized equipment configurations based on product drawings, sheet material, production capacity, and workshop layout.
