Introduction to CU Channel Roll Forming Machine
CU channel roll forming machine is specialized equipment used to produce light steel channels (CU profiles) for ceiling grids and partition wall systems in construction. Below is a detailed overview:
1. Machine Function**
- Processes metal coils (typically galvanized steel strips) into CU-shaped channels through multi-stage roll forming.
- Customizable for different sizes (e.g., 50/60/75 series) and thicknesses (0.4-1.2mm).
2. Core Components
Uncoiling System: Automated feeding with tension control.
Straightening & Guide Unit**: Ensures flat material entry.
Roll Forming Station**: 10-20 precision rollers (Cr12MoV alloy steel molds) progressively shape the profile.
Cutting System: Hydraulic/servo-driven, ±0.5mm accuracy.
Control System: PLC + HMI with preset parameters for various specs.
3. Technical Specifications
Speed 15-30 m/min
Motor Power: 15-30 kW (main drive)
Material Width**: 100-250mm (profile-dependent)
4. Process Advantages
Single-pass forming: No welding required; high structural strength.
Precision**: ±0.3mm tolerance for web width/flange height.
Surface protection**: Special roller treatment prevents coating damage.
5. Applications
- Framing for calcium silicate boards, gypsum panels, etc.
- Widely used in suspended ceilings & drywall systems (offices, hospitals, malls).
6. Selection Guide
Choose mechanical/hydraulic cutting based on production volume.
- Optional punching unit for pre-pierced channels.
- Prioritize models with auto-lubrication for extended mold life.
