The 16″ 4V Soffit Roll Forming Machine is a high-performance production line designed to produce durable, precise soffit panels for residential and commercial building applications. By integrating advanced roll forming technology with intelligent automation, this system enables manufacturers to achieve higher efficiency, consistent quality, and flexible production capacity.
Whether you are expanding into the soffit market or upgrading your current production line, this machine provides a reliable solution that reduces labor costs and increases productivity.



Complete Automated 16″ 4V Soffit Roll Forming Machine
This soffit panel roll forming machine operates as a fully integrated production system, covering every step from coil loading to finished product collection. Each component works together seamlessly to ensure stable operation and high production output.
The production line includes:
- Hydraulic uncoiler with coil loading car
- Material guiding and feeding table
- Precision roll forming system
- Hydraulic flying shear cutting system
- PLC intelligent control system
- Hydraulic power station
- Finished product receiving table
Because every stage of the workflow is carefully engineered, operators can run the machine easily while maintaining excellent production stability.

High-Speed Roll Forming for Increased Productivity
Efficiency plays a critical role in modern metal processing. Therefore, this machine uses a multi-station roll forming structure with 18 forming stations, ensuring accurate shaping while maintaining high production speed.
The system can reach forming speeds of up to 80 ft/min, while some optimized production configurations can achieve even higher line speeds. As a result, manufacturers can significantly increase daily output and meet large-volume orders without sacrificing product precision.
Additionally, the machine maintains stable performance even during long continuous production cycles.
To guarantee clean and accurate panel lengths, the production line uses a hydraulic flying shear cutting system. Unlike traditional stop-cutting systems, flying shear technology cuts the panel while the line continues moving, which greatly improves efficiency.
The cutting blades are manufactured from GCr12 quenched tool steel, providing excellent wear resistance and long service life. This design helps prevent deformation and ensures smooth panel edges with minimal material waste.
As a result, manufacturers can deliver panels with consistent dimensions and professional finishing quality.

The machine adopts a PLC control system with touch screen interface, allowing operators to control the entire production process from a central panel.
Users can easily set:
- Panel length
- Production quantity
- Forming speed
Once parameters are entered, the system automatically controls the production process with a cutting tolerance of approximately ±1.5 mm.
This intelligent control approach simplifies machine operation, reduces manual errors, and improves production efficiency.

Optimized Soffit Panel Design for Modern Construction
The soffit profile produced by this machine was carefully developed to meet the needs of residential construction markets. Several structural improvements help installers complete projects more efficiently while ensuring long-term durability.
Key profile features include:
- 16-inch panel width for efficient coverage
- Standard rib height for structural stability
- Concealed S-lock lap design for secure panel connections
- Flat-top ribs that allow easy screw or nail fastening
- Integrated nail slots for flexible installation
- Special weep holes designed to drain water while blocking most insects
These design elements improve both installation convenience and long-term building performance.
Durable Machine Structure for Long Service Life
Durability is essential for continuous industrial production. Therefore, the soffit roll forming machine uses a heavy-duty welded steel plate frame that provides excellent rigidity and vibration resistance.
Key structural components include:
- 45# precision-machined shafts
- D2 chrome-plated forming rollers
- Heavy-duty transmission system
- Stable hydraulic power unit
These components ensure smooth operation, reduce maintenance frequency, and extend the overall service life of the equipment.
