Manufacturing Capability & Process Control
Cold rolled aluminum coils are produced through controlled multi-pass deformation at room temperature, followed by annealing to achieve required mechanical and forming properties.
Core Production Systems
- Multi-stand cold rolling mills with AGC (Automatic Gauge Control)
- Online laser thickness monitoring (typical capability ±0.01–0.02 mm depending on specification)
- Tension-controlled rolling system for flatness stability
- Continuous and batch annealing furnaces for recrystallization control
- SPC (Statistical Process Control) applied to key production stages
