Steel Belt Spiral Duct Machine With 4 Sets Forming Rollers

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.
