HYRUN engineers heavy-duty spiral duct machines featuring 4 precision-angled rollers for superior forming stability. Designed for high-speed production (≤25 m/min) of galvanized/stainless steel ducts (Ø80–1250 mm), our system delivers SMACNA-compliant profiles with ±0.5 mm OD tolerance and airtight edge lock seams, minimizing labor and maximizing airflow integrity.
Features of steel belt spiral duct machine With 4 Sets Forming Rollers
Robust Quad-Roller System: HYRUN's 4 hardened steel rollers eliminate oval deviation (±0.5mm max).
Precision Diameter Control: Laser-calibrated OD tolerance ±0.5mm ensures SMACNA-compliant round ducts.
High-Speed Production: Processes ≤25 m/min for galvanized/stainless coils (0.4-1.2mm thickness).
Airtight Seam Technology: Patented edge lock seam achieves<2% leakage (ASHRAE 90.1 standard).
Automated HMI Operation: HYRUN's touchscreen interface enables one-operator control and job memory.
Steps to Use and Points to Note of Steel Belt Spiral Duct Machine With 4 Sets Forming Rollers
Pre-Production Setup: Mount HYRUN-certified mold matching duct diameter; calibrate roller pressure symmetry to ≤5% variance using HMI diagnostics.
Material Feeding: Load galvanized/aluminum coil (0.4–1.2mm thickness); ensure edge alignment within ±0.3mm via laser guides.
Production Run: Operate at ≤25 m/min; monitor seam engagement force (≥120N) and OD tolerance (±0.5mm) on touchscreen.
Critical Precautions: Never disable safety curtains during jam clearance (OSHA 1910.212). Lubricate rollers weekly with HYRUN Teflon-free grease to prevent material galling. Replace rollers at 50K cycles to maintain SMACNA profile compliance.
