How oem cold roll forming machine Works
The OEM cold roll forming process involves:
Material Feeding
- Coiled metal stock loaded onto a de-coiler
- Fed through a straightener to correct flatness/alignment
- Enters forming section
Forming
- Sheet passes through series of roller stations
- Rollers apply pressure to bend metal incrementally
- Desired profile achieved gradually over multiple roller passes
Cut-Off & Customization
- Formed profile cut to length by rotating shear
- Holes punched, hardware inserted, ends trimmed etc.
- Finished parts extracted by catch table or conveyors

Component shaping in each vertical requires specific design considerations addressed through the custom OEM equipment.
Working Principle of oem cold roll forming machine
The fundamental working concept behind any cold roll forming system involves passing flat sheet metal strip stock through consecutive roller stations to induce incremental bending until the desired profile is gradually formed across the length of the material.
Table 3: Central Principles of Cold Roll Forming Process
| Principle | Explanation |
|---|---|
| Incremental Bending | Many small bends distributed over several roller passes shape profile |
| Continuous Processing | Coil continuously fed through rollers at constant speed |
| Cold Working | Room temperature forming preserves material properties |
| Compressive Force | Rollers apply localized pressure to bend sheet |
| Progressive Shaping | Final form achieved gradually through roller sequence |
Understanding these core mechanics of bend formation helps appreciate how OEM roll formers can create customized geometries.
Key Process Parameters
Additionally, knowledge of certain key process parameters is important for designing effective OEM cold roll forming lines:
- Thickness and Grade of Metal – Determines force required for forming
- Width of Coil Stock – Affects number of forming heads/stations needed
- Inside Bend Radius – Impacts roller dimensions and layout
- Bending Angle – Sequential bending add up to shape profile
- Number of Passes – More passes allow greater control over incremental shaping
By factoring these specifications into equipment concept development, OEM roll former performance can be maximized.
