On factory floors where every minute matters, the unglamorous hero is often the din rail roll forming machine. I’ve stood beside these lines at 6 a.m., coffee in hand, watching galvanized strip turn into perfectly straight DIN rails—click by precise click. It’s oddly satisfying, and, to be honest, the difference between a smooth cabinet build and an afternoon of swearing at misfit accessories.
Cabinet makers and switchgear OEMs want faster changeovers, tighter tolerances, and traceability. The Electric Rail Roll Forming Machine from Yingyee targets exactly that: servo-driven punching, PLC control, and consistent geometry for EN/IEC 60715 mounting rails. Many customers say scrap drops noticeably once profiles and hole patterns are dialed in—surprisingly, even small coil quality swings can be smoothed by better leveling and straightening modules.
| Model | Electric Rail Roll Forming Machine (DIN) |
| Material | Galvanized steel strip (ASTM A653), Z120–Z275; optional AlZn |
| Thickness | ≈0.6–2.0 mm (real-world use may vary by profile) |
| Yield strength | ≈235–550 MPa |
| Line speed | 10–25 m/min adjustable |
| Roll stations | 12–20 (profile dependent) |
| Punching/Cut-off | Servo pre-punch + hydraulic fly-shear |
| Dimensional tolerance | ±0.15 mm typical; length control ±0.5 mm |
| Control | PLC (Siemens/Delta), HMI recipe library |
| Service life | 10–15 years with standard maintenance |
Decoiler → leveling → servo feeder → pre-punch → roll forming → straightening → fly-cut → runout table → QC. Methods include light oiling, burr control, and gauge checks. Rails are verified to EN/IEC 60715 dimensions; coating integrity can be validated via ISO 9227 or ASTM B117 salt-spray. A few lines I saw ran Z140 galvanized strip and still hit 240 h neutral salt spray without red rust at cut edges after post-oiling—results vary with coil and handling.
Industries: switchgear, panel building, HVAC, rail transit cabinets, data center PDUs. The big wins are consistency (flatness, camber), throughput, and quick recipe changeover. In fact, one mid-sized European panel builder reported din rail roll forming machine changeover under 12 minutes and scrap below 1.5% on 8-hour shifts once operators got comfortable.
Hole patterns, logo embossing, lot marking, anti-rotation features, profile variants (e.g., 35 mm top-hat, G-rail), and packaging automation. Also, optional vision checks for hole presence—handy when running mixed orders.
| Vendor | Strengths | Considerations |
|---|---|---|
| Yingyee (Shijiazhuang, Hebei) | Solid value, fast lead times, IEC-focused tooling, CE-ready | Advanced analytics optional; specify brand of electrics up front |
| Regional Trader | Local support, multi-brand sourcing | Spec variance; pricing ≈10–20% higher |
| EU Brand | Premium controls, deep diagnostics | CapEx premium; longer spares lead time |
A Central European switchgear factory swapped imports for in-house rails using a din rail roll forming machine. Result: lead time cut from 3 weeks to 3 days, inventory down ≈28%, and fewer fit-up issues with terminal blocks (EN 60715 tolerance kept tight). Feedback from the line chief: “Noise was lower than expected and the length accuracy stayed inside half a millimeter.”
Machines are typically built to CE (Machinery Directive) with ISO 12100 risk assessment, electrical safety to EN 60204-1. Rails align to IEC/EN 60715; material to ASTM A653 or equivalent. Factory address: Room B1106, Zhongliang Plaza, No.345 Youyi North Street, Xinhua District, Shijiazhuang, Hebei. It seems basic, but documenting coil certs and keeping a simple SPC chart for rail height pays off over time.
