Roll Forming Process Overview
The pedal plate roll forming process consists of:
- Coil Loading – Steel or aluminum coil loaded
- Feeding – Coil fed into roll former infeed
- Punching – Holes punched in plate at early stage
- Forming – Plate formed gradually as it passes through stations
- Cutoff – Formed plate cut from coil at specified length
- Output – Finished pedal plate extracted
The process is continuous and optimized for high output.

FAQ
What materials can be roll formed into pedal plates?
Most commonly roll formed materials are low carbon steel, stainless steel, and aluminum alloys 6061 and 7075.
What thicknesses can be roll formed?
Pedal plates typically use metal between 1 mm to 3 mm thickness. Thicker materials require more robust roll forming equipment.
How long do pedal plate roll former tooling changes take?
Basic machines require 1-2 hours. With advanced quick change systems, under 15 minutes is possible.
Can pedal plates be powder coated after roll forming?
Yes, powder coating can be done in a batch process or optionally integrated as an inline automated process after roll forming.
What tolerances are held on roll formed pedal plates?
Standard roll forming can achieve +/- 0.5 mm accuracy. Precision CNC machines with servo drives can hold +/- 0.25 mm or better.
Conclusion
Roll forming provides bicycle part manufacturers an efficient automated process to produce quality pedal plates in medium to high volumes. Integrated punching and cutting, quick changeovers, and powder coating integration allow flexibility combined with speed. While requiring an initial investment, over time the automated productivity of pedal plate roll forming results in lower overall part costs and lead times, benefitting OEM customers. Properly utilizing this technology can give manufacturers a competitive advantage in the bicycle component market.
Additional Frequently Asked Questions (FAQ)
1) What coil specs are best for a pedal plate roll forming machine?
Steel: 1.0–3.0 mm low-carbon or stainless; Aluminum: 1.2–3.0 mm (6061/7075). Coil width is typically net blank width + 8–20 mm for edge trim and guiding.
2) How can I minimize twist, camber, and hole-to-edge drift on pedal plates?
Use an entry straightener, symmetric pass design, anti-camber rolls, and servo-guided lateral guides. Add inline vision to verify hole position to ±0.2 mm before cutoff.
3) Are all-electric roll formers worth it for bicycle pedal plates?
For small-to-mid OEMs, all-electric lines cut energy use 10–20% and simplify maintenance (no hydraulics). ROI is strongest with high uptime or when energy tariffs are high.
4) Can I integrate knurling, embossing, or thread forming inline?
Yes. Light emboss/knurling can be added mid-line; thread forming is feasible via pre-punch + downstream tapping cell. Maintain pass clearance to protect surface features.
5) What is a good OEE target for a pedal plate line with quick-change tooling?
Single-profile: 70–80% OEE; multi-profile with cassettes: 55–65%, assuming changeovers in 15–30 minutes and scrap under 1%.
