Overview
একটি OEM metal roll forming machine is a versatile industrial equipment system used to efficiently mass produce long lengths of precision custom metal parts and profiles for original equipment manufacturers.
The continuous roll forming process shapes metal coil feedstock into various rails, frames, enclosures and structural components using a series of rotating roller dies.
This guide provides a comprehensive overview of OEM roll former technology, including:
- Machine types and components
- How the roll forming process works
- Design considerations
- End use applications
- Material and specification standards
- Cost analysis
- Comparisons with other metal fabrication methods
Gaining insight into OEM metal roll former capabilities assists manufacturers evaluating optimized production solutions for metal components used in specialized equipment and products.
Types of OEM Metal Roll Forming Machines
There are two primary machine configurations for high volume OEM parts production:
Fixed Head Roll Formers
- Typically 10-16 forming stations
- Common base profiles
- Lower tooling cost
- Repeat jobs
Quick Change Roll Formers
- Individual stations per head
- Flexible tooling for profile variations
- Higher output variety
- Frequent form changes
Main Components of a Metal Roll Former
A typical OEM metal roll forming system integrates these main sections:
Coil Payoff Reel
- Holds raw coil at unwind station
- Feeds strip through process
Entry Guides
- Align and straighten strip
- Optimize material feed
Accumulator/Bridle
- Creates back tension zone
- Smooths flow variations
Forming Stations
- Progressive die rollers shape material
- Number & type determine profile
Cutter
- Shears finished parts to length
- Pneumatic, servo electric
Exit Conveyor
- Transfers finished product
- Links to secondary operations
Automation Controls
- HMI and PLC hardware
- Touchscreen programming
- Data feedback
How Metal Roll Forming Machines Work
The OEM roll forming process shapes metal coil feedstock into rails, frames and custom profiles by bending and forming the strip material incrementally as it passes through a series of roller die stations:
- Powered coil payoff reel feeds raw coiled strip into initial machine guides
- Entry guides align strip and feed into first roller station
- At each station, machined rollers make precision bends and forms
- Strip exits slightly more formed moving to subsequent stations
- Finished custom profile emerges at end of forming line
- Profile cutoff to length by pneumatic or servo shear
- Formed parts conveyed for additional fabrication
The number of roller die stations determines possible shape complexity. Quick changeovers accommodate low to high mix production.

FAQ
What metals work with OEM roll forming?
All ductile metals can use roll forming including low carbon steel, stainless steel, aluminum, copper, and titanium alloys. Hardened materials may require specialized tooling.
What tolerances are possible with OEM roll formed parts?
Roll formed components can reliably achieve profile tolerances between +/- 0.1 mm to +/- 0.25 mm for quality machines depending on the material gauge.
How long can an OEM roll formed metal part be?
Standard maximums with support tables are around 18 meters (60 feet). Custom long bed machines can produce sections over 30 meters (100 feet).
How thick of metal can an OEM roll former handle?
Thicknesses from 0.15 mm (30 gauge) to about 6 mm (1/4 inch) are typical for an average OEM roll former. Beyond that may require custom heavy-duty equipment.
