HYRUN Rectangular Duct Machine Work Process

Coil Feeding & Leveling:
Steel coil is auto-feed through precision rollers, eliminating curvature for flawlessly flat material.
Corner Notching & Bending:
Servo-adjusted dies notch corners and progressively bend sides at 90° with ±0.5mm dimensional accuracy.
Seam Locking:
Dual-head rollers form Pittsburgh/TDC locks on longitudinal edges for rigid, airtight seams.
Auto Flange Forming:
TDF/TDC flanges are robotically installed before finished ducts are formed.
PLC-Controlled Folding:
Metal sheet folding to programmed size during continuous operation.

HYRUN Rectangular Duct Machine Core Functions

Coil Decoiling & Leveling:
Servo-driven systems unwind/flatten metal sheet coils for precision processing.
Ribbing & Punching:
Forms stiffening ribs and punches notches/holes (corners, supports, fasteners).
Seam & Flange Forming:
Creates Pittsburgh locks and TDF flanges (±0.3mm) on sheet edges.
Bend Preparation:
Pre-forms longitudinal edges for subsequent duct assembly.
Component Output:
Produces ready-to-assemble duct sections with connection-ready profiles.

Advantages of HYRUN Square Duct Machines

HYRUN machines form airtight Pittsburgh Lock Hem seams with ±0.5mm edge alignment, eliminating air leakage while maintaining uniform corner rigidity for commercial HVAC ducts.

Design Advantage: Heavy-gauge quick-change tooling adapts to duct sizes in <3 minutes, while modular frames ensure 24/7 stability and reduce setup downtime by 40%.
