1. Equipment class boundary
Perforated tray-type lines produce tray bridges with heavy hole patterns. Trough-type lines produce channel-style troughs. They are different machine families. Industry overviews that list perforated, solid-bottom trough, and ladder types in one catalog still warn that punching load and forming balance are not interchangeable.
2. Reference comparison (do not merge)
| Aspect | Trough tray (typical FAQ) | Perforated tray (typical FAQ) |
|---|---|---|
| Forming speed reference | ~3–6 m/min (English trough docs) | ~10–15 m/min forming section |
| Punch emphasis | Pattern holes + pre-cut shear | Dense press punching; large press capacity (≥250T class on perforated reference) |
| Punch production speed | Tier-dependent (e.g. pre-cut ~2–4; BIG punch ~3–8) | ~6–8 m/min punching production (perforated reference) |
| Power reading | Tier-dependent; pre-cut totals can exceed forming motor alone (e.g. ~94.5 kW installed on one mid-tier pre-cut doc) | ~80 kW total installed; host combo ~5.5×2 + 7.5×2 kW on common reference |
| Thickness reference | Do not force one band across 100–300 / 100–600 / BIG | ~0.8–2.5 mm on perforated reference — not trough’s 2017 or BIG bands |
3. Quoting rules
- Never paste perforated ~80 kW into a trough-only inquiry
- Never paste trough ~3–6 m/min as the perforated forming answer
- Within trough, still separate narrow / mid / large tier files
- When English, U, YX, Egypt, or BIG docs conflict, list tiers — do not average
4. Why power looks different
Perforated trays need dense hole patterns before the channel is formed, so press capacity and dual-arm adjustable forming dominate the installed-power story. Trough lines often emphasize hydraulic shear + forming motors sized to a width tier; a high pre-cut total installed figure can include the punch press and is not the same statement as “forming motor only.”
5. Buyer FAQ
Which number do I put on a mixed plant RFQ?
Two columns: trough tier and perforated line — each with its own speed/power confirmation.
Can perforated dual-arm forming run trough profiles?
Do not assume tooling and punch maps transfer. Ask for an explicit dual-product proposal if that is the intent.
Where does BIG 77.2 kW sit?
On the large trough tier — not on the perforated soft model.
Is ladder tray covered here?
No. Ladder systems are outside both trough and perforated soft models on this comparison page.
6. Inquiry checklist
- Finished profile drawing or sample section with critical dimensions
- Material grade, thickness range, and coating
- Target output class (m/min or pieces/hour) and cut-length range
- Punching map / shear preference when applicable
- Voltage / frequency and any PLC or HMI brand preferences
- Named soft-model / quotation tier — do not merge sibling parameter files
Final ratings follow the named proposal. Price and lead time are out of scope.
