| Specification | NDCSF-410DR | NDCSF-420DR |
|---|---|---|
| Designed speed (meters/min) | 250 | 250 |
| Working speed (meters/min) | 200 | 200 |
| Effective width (mm) | 2200-2500 | 2200-2500 |
| Corrugated roller diameter | φ410mm | φ420mm |
| Heating type | Steam heating | Steam heating |
| Changing roller time | 2-3 mins | 2-3 mins |
Both share the same 250m/min design speed, 200m/min working speed and 2200-2500mm effective width — the difference is the corrugated roller diameter: φ410mm on the NDCSF-410DR versus φ420mm on the NDCSF-420DR.
Changing the corrugated roller takes only 2-3 minutes on both models, keeping line downtime to a minimum.
The upper and lower corrugated rollers are made from 48CrMo high-quality alloy steel with a hardness above HV1200, giving long service life under continuous high-speed operation.
It refers to the dual corrugating roller arrangement, with the upper roller, pressure roller and rubber roller lift all driven by pneumatic control for fast, precise corrugating roller engagement and separation.
Yes — installation, commissioning and operator training are included with every machine, with after-sales support available.
