III. Core Technical Advantages

1. Rapid, Stepless Profile Switching (No Mold Changes Required)
This is the core advantage distinguishing this series of equipment from traditional single-specification production lines. Traditional equipment requires machine downtime to dismantle rollers and recalibrate parameters when switching profile specifications—a process taking 2–4 hours that severely disrupts production continuity. This series utilizes a stepless adjustment system, allowing for precise, millimeter-level adjustments within the specified range to produce both standard and non-standard profiles. No forming roller changes are required; semi-automatic switching takes just 8 minutes, while fully automatic switching takes only 3 minutes.

2. Multi-Profile Capability and Flexible Production
A single production line can manufacture various types of purlins, such as C- and Z-sections (interchangeable) or C- and U-sections (interchangeable). Unlike traditional setups that require separate production systems for different profiles, this series reduces equipment investment while enhancing production flexibility and equipment utilization. Its ability to roll-form two different profiles saves the user both purchasing costs and floor space.

3. Fully Automated PLC Control and Intelligent Production
The equipment features fully automated PLC control, integrating functions such as automatic decoiling, leveling, hydraulic punching, automatic length measurement, and automatic cutting. It automatically performs punching, cutting, and forming based on input parameters like purlin length, longitudinal hole spacing, and quantity. Key parameters—such as rolling force, current, and temperature—are monitored in real-time; the system triggers an immediate alarm and halts operation upon detecting anomalies, thereby preventing batch defects. 

4. High-precision forming and superior quality
Roll shafts are made of 40Cr steel, heat-treated (quenched and tempered) to a hardness of HB280.
Forming dies are made of GCr15 steel, heat-treated (quenched) to a hardness of HRC 56–62.
The transmission system utilizes a gearbox drive; each forming stand is equipped with a dedicated gearbox, ensuring the equipment can operate continuously under high-intensity conditions.
Forming speeds reach up to 15–30 m/min.
Precision during product changeovers is maintained within ±0.1 mm.

5. Robust, durable, stable, and reliable
The machine base is a welded steel structure that has undergone tempering to eliminate internal stress and prevent deformation.
Forming stands feature a cast-iron structure that has been tempered, ensuring high strength and a long service life.
The drive system employs a gear motor with variable frequency control, ensuring accurate and reliable speed regulation, cut-to-length precision, and positioning.
