High Precision Fixed Size C Purlin Roll Forming Machine with Mold Cutting

This XINNUO C purlin machine is a specialized roll forming solution for manufacturers who require high-volume production of a single, fixed-size C-channel. By eliminating the complexity of size-adjustment mechanisms, this machine offers enhanced rigidity and stability. Its standout feature is the precision mold shearing system, which provides a higher quality finish compared to standard post-cutting knives.

Main Features

• Precision Mold Cutting System: Provides a clean, deformation-free cut, significantly reducing follow-up processing time.
• Single Profile Optimization: Fixed roller design ensures maximum machine stability and consistent profile geometry over long production runs.
• Light-Gauge Specialist: Specifically calibrated for 0.9-1.2mm thickness, preventing material stretching or surface damage.
• Compact & Rigid Frame: Built on a heavy-duty 300H steel base for vibration-free operation at high speeds.
• Automated PLC Control: Simplifies operation with multi-language support and precision length management.

Technical Specifications

• Material Thickness: 0.9–1.2 mm
• Material Type: GI, cold-rolled steel, high-tensile steel
• Forming Speed: 8–15 m/min (excluding cutting time)
• Number of Forming Stations: 12–14 rows (designed for specific profile)
• Shaft Diameter: Φ70 mm (40Cr precision ground)
• Roller Material: GCr15 bearing steel with hard chrome plating

• Voltage: 380V/50HZ/3PH (Customizable to local standards)

Machine Configuration

1. Manual Decoiler: 3-ton capacity for steel coil loading.
2. Feeding & Leveling: Ensures the material enters the rollers flat and centered.
3. Roll Forming Unit: Precision-engineered rollers for the specific C-profile.
4. Hydraulic Mold Shear: Custom-built mold for the target profile size.
5. PLC Control Cabinet: Industrial-grade control system (Delta/Siemens optional).
6. Run-Out Table: 6-meter non-powered collection rack.

Applications

• Light Steel Structure: Roof and wall purlins for prefab houses.
• Industrial Racking: Consistent C-channels for warehouse storage systems.
• Solar Mounting: Support rails for PV panel installations.

Production Process

Coil Loading → Uncoiling → Feeding & Guiding → Precision Roll Forming → Hydraulic Mold Cutting → Finished C Purlin

Why Choose This Machine

For projects where only one size of C purlin is needed, this fixed-size machine outperforms adjustable models in terms of price-to-performance ratio, cutting quality, and mechanical longevity. The mold cutting technology ensures every piece meets strict engineering tolerances.

FAQ

Q: Can this machine produce different sizes of C purlins? A: No, this is a fixed-size machine optimized for a single profile to ensure maximum precision and lower equipment costs.

Q: What is the advantage of mold cutting over universal cutting? A: Mold cutting uses a blade shaped exactly like your profile. This prevents profile deformation during the cut and results in a much cleaner edge.

Q: What is the production speed? A: This machine operates at a stable speed of 8-15 m/min depending on the cut length and material feeding.

Q: What power supply is required? A: Standard configuration is 380V/50HZ/3PH, but we can customize the electrical system to meet your local voltage requirements.

Q: Does XINNUO provide the cross-section drawing before production? A: Yes, our engineers will confirm the exact dimensions with a technical drawing based on your requirements before we begin manufacturing.
