Collar Making Machine for HVAC Spiral Duct Production

The StanGroup HVAC Spiral Duct Collar Making Machine is designed for HVAC duct manufacturers and sheet metal fabrication shops producing round duct collars, take-offs, and connector sleeves for spiral duct systems. By combining multiple forming operations in one machine, it helps streamline production, reduce manual handling, and maintain consistent results across production runs.

For businesses comparing a Lockformer collar maker with alternative duct fabrication equipment, this machine offers an integrated approach to collar production. Notching, bead forming, end crimping, and strip shaping are combined in one workflow, reducing the need to perform each operation separately. The right configuration depends on your required collar diameters, sheet metal specifications, and production volume.

Technical Specifications

How the HVAC Collar Making Machine Works

The machine combines several stages of sheet metal forming in a single production workflow. This setup helps HVAC fabrication shops reduce separate handling steps when manufacturing round connectors for spiral duct systems.

• Notching: Creates the required notches in the strip for the intended joining or fastening method.
• Bead Forming: Forms a reinforcing bead or locating feature according to the tooling configuration.
• End Crimping: Shapes the designated end of the connector to facilitate fitting into a compatible duct section.
• Round Forming: Shapes the processed strip into a round collar or connector within the machine's supported diameter range.

The finished part and its connection method depend on the tooling, material, diameter setting, and assembly requirements. Confirm the intended collar design with the manufacturer before ordering.

Applications in HVAC Duct Fabrication

This machine is intended for production environments manufacturing round sheet metal components used in HVAC ductwork. Depending on the tooling and finished-part design, applications may include:

• Round duct collars and take-off connectors.
• Connector sleeves for compatible spiral duct systems.
• Round fittings used in commercial and industrial ventilation installations.
• Repeat production of sheet metal duct components in HVAC fabrication shops.

Key Benefits for Sheet Metal Shops

• Multiple Operations in One Workflow: Combines several forming stages to reduce the need for separate manual operations.
• Consistent Production: A repeatable forming process helps operators produce batches with more uniform dimensions when the machine is correctly set up.
• Compact Workshop Layout: Integrates several functions into a single machine rather than distributing them across separate workstations.
• Production Flexibility: The supported diameter range allows production of different collar sizes, subject to tooling and setup requirements.
• Less Manual Handling: Reduces transfers between individual processing steps and can simplify the production workflow.

Electrical Requirements, Delivery and Support

Before ordering, confirm the required voltage, phase, frequency, installation conditions, and compatibility with your facility's electrical supply. North American electrical configurations should be specified and confirmed with StanGroup before shipment.

For an accurate quotation, provide your required collar diameters, sheet metal material and thickness, expected production volume, and delivery location. StanGroup can then confirm the appropriate machine configuration, available options, shipping arrangements, and applicable warranty and support terms.

Frequently Asked Questions

How does the StanGroup machine compare with a Lockformer collar maker?

Both are relevant options to consider when evaluating equipment for HVAC collar fabrication. Compare the supported diameter range, material capacity, forming operations, production cycle, electrical requirements, tooling, service support, and total delivered cost. Verify these details against the exact Lockformer model and the proposed StanGroup configuration before making a purchasing decision.

What sheet metal thickness can the machine process?

The listed capacity is 0.4–0.7 mm, approximately 28–24 gauge depending on the material. Actual compatibility can vary with metal type, mechanical properties, and tooling. Confirm the allowable thickness range for your intended material with the manufacturer.

What electrical supply is required?

The listed options are 220 V or 480 V, three-phase, 60 Hz. Confirm the available configuration, motor rating, control requirements, and connection specifications with StanGroup before ordering. A qualified electrician should verify compatibility with your facility.

Can the machine produce SMACNA-compliant duct connections?

Compliance depends on the finished fitting design, dimensions, assembly method, applicable standard, and installation requirements. Confirm that the intended collar and duct connection meet the specifications required for your project; machine capabilities alone do not establish compliance.

How can I request a quotation?

Contact StanGroup with your required collar sizes, material specifications, production needs, and delivery ZIP code or destination. Request confirmation of the machine configuration, lead time, shipping cost, warranty coverage, and available technical support before placing your order.
