1. Working Principle
Roll Forming: Metal coil materials (e.g., steel, aluminum) pass through a series of sequentially arranged rollers (dies) to gradually bend and shape them into predefined cross-sectional profiles (e.g., wave, square tube, or custom shapes).
Continuous Production: The machine feeds materials continuously, enabling high-efficiency, stable assembly-line operations suitable for mass production.
Integrated Processes: Combines punching, cutting, and bending to complete forming, perforation, and length cutting in one pass.
2. Core Components
Uncoiler: Holds and unwinds metal coils automatically.
Guiding and Leveling Unit: Ensures flat and aligned material entry into the rollers.
Roll Forming Station: Multiple pairs of precision rollers that progressively shape the material.
Punching Unit (Optional): Adds holes (for connections or decoration) during forming.
Cutting System: Hydraulic or pneumatic shear to cut formed fences to preset lengths.
Control System: PLC or CNC for adjusting speed, length, pressure, etc.
3. Key Applications
Product Types: Security fences, perimeter railings, balcony guards, highway barriers, etc.
Material Compatibility: Galvanized steel, stainless steel, aluminum, color-coated steel (thickness: 0.3-3mm).
Profile Designs: Customizable C/U channels, wave patterns, decorative (openwork) designs.
4. Advantages
High Efficiency: Produces 5-30 meters per minute (depending on complexity), far exceeding manual or stamping methods.
Precision: Precision-machined rollers ensure consistent dimensions and shape accuracy.
Low Waste: Material utilization exceeds 95%, minimizing scrap.
Flexibility: Swap roller sets to produce different fence designs.
Automation: Reduces manual labor and operational costs.
