What materials can be roll formed into wall sheets?
- Cold rolled steel, galvanized steel, stainless steel, aluminium sheets up to 2 mm thickness. Not recommended for thicker plates above 3 mm.
What should be the flatness and surface finish of the coil?
- Coil flatness tolerance up to 3 mm per meter width is acceptable. Surface defects may mark the finished profiles.
What are the power requirements?
- Wall sheet roll formers typically need 15 – 30 kW installed power depending on speed and capacity. Three phase 415 V AC supply is preferred.
How to adjust the roll forming stands?
- Stands are adjusted by laser alignment or numerically controlled actuators. Keyed shafts, screwn down and shims allow manual adjustment along with Gauging stations.
Hangi güvenlik önlemleri gereklidir?
- Emergency stop buttons, overload protection, strip containment guides, safety fences and light curtains to stop on obstruction. Acoustic covers reduce noise.
What digital controls are included?
- PLC or HMI touchscreen controls for production monitoring, parameters adjustment and automated sequencing of machine. Servo systems allow precision control.
What is the normal maintenance routine?
