IV. Key Advantages & Competitive Edge
1. Wide-Width Efficiency
1200mm feed → **Reduced overlapping seams** (ideal for large factories/warehouses), minimizing leakage risks.
2. Flexible Production
Quick-change mold system (≤3hrs for profile switching), supports custom waveforms (CAD drawings required).
3. High-Precision Forming
German-engineered roller system ensures wave symmetry (deviation ≤0.8mm/m), preventing installation interference.
4. Energy-Saving Design
Servo motor per-station drive saves 30% energy vs. chain transmission.
5. Low Maintenance Cost
Oil-immersed gear lubrication + wear-resistant bearings (service life ≥100,000 hours).
