Product Introduction
The Double-Layer Roofing Sheet Roll Forming Machine is an industrial-grade manufacturing solution engineered to produce two distinct metal roofing profiles on a single machine footprint. By stacking two independent forming decks (typically an architectural glazed step tile profile on the upper deck and a trapezoidal/corrugated profile on the lower deck), this system enables panel manufacturers to double their product capability while optimizing factory floor space and reducing capital expenditure.
Key Technical Advantages
-
Dual-Profile Space-Saving Architecture: Integrates two complete roll forming lines into a single sturdy chassis. Switch between upper and lower deck production simply by feeding the coil into the designated deck.
-
Precision-Engineered Forming Rollers: Manufactured from forged 45# high-grade steel, CNC-machined, and hard-chrome plated (0.05 mm thickness) to prevent surface scratches on pre-painted steel (PPGI) and enhance roller longevity.
-
Automated Smart PLC Control System: Equipped with a multi-language touchscreen HMI (Delta) for precise control over panel length, production quantity, and cycle timing, featuring built-in error diagnostics and emergency safety stops.
-
Hydraulic Profile Shearing & Stepping: Features high-precision hydraulic cutting dies crafted from Cr12/SKD11 die steel. The system performs clean, burr-free post-cutting and step-stamping without thermal deformation.
-
Heavy-Duty Structural Frame: Constructed with welded H-beam steel and solid guidance plates to ensure minimal operational vibration and high stability under maximum load conditions.
