Frequently Asked Questions (FAQ)
1) What profiles can a CZ Roll Forming Machine produce?
- C, Z, and occasionally Σ/hat channels for purlins, girts, studs, and trusses. Many machines offer auto size-change between C↔Z without manual roll swaps.
2) What line speeds and thickness ranges are typical?
- For structural purlins: 15–45 m/min on 1.2–3.0 mm GI/Al-Zn steel; lighter gauges (0.8–1.2 mm) can run 45–70 m/min when punching density is low and a servo flying shear is used.
3) How does auto size-change improve productivity?
- Servo-adjusted stands and tool presets switch web/flange/lip dimensions and C↔Z orientation in under 5–10 minutes, cutting changeover time by 60–80% versus manual setups and reducing startup scrap to <1.5%.
4) Which substrates and coatings are best for CZ purlins?
- Galvanized (ASTM A653 Z275) for inland; Al–Zn (AZ150–AZ200 per ASTM A792/EN 10346) for heat/UV; Zinc–Magnesium (ZM90–120 EN 10346) for superior cut-edge corrosion; high-strength steel (G550/S550GD) to reduce weight without sacrificing capacity.
5) How do inline punching systems affect quality and speed?
- Servo punching matched to the line encoder maintains hole-to-end accuracy ±0.8–1.2 mm at 30–40 m/min; dense patterns may reduce speed 15–25%, but closed-loop control keeps slot position within tolerance to ensure bolt-up fit on site.
2025 Industry Trends
- Electrification: All-electric punching and flying shears replace hydraulics, cutting energy use and oil-related downtime.
- Vision-in-the-loop QC: Cameras/lasers verify hole pitch, web/flange width, and twist; real-time feedback trims error drift.
- Smart alloys: Wider adoption of Zn–Mg (ZM) and Al–Zn (AZ) substrates for extended corrosion warranties on industrial roofs.
- Digital recipes: Preset libraries for common C/Z sizes reduce human error and enable rapid, traceable changeovers.
- Connected factories: OPC UA/MQTT data streams to MES/ERP for traceability, SPC, and warranty documentation.
