Trough Tray Punch Line Speed vs Forming Speed

1. Why two speeds appear

On a pre-cut trough cable tray line, punching and length cut usually happen before the strip enters the roll former. Punch cadence (hole map + press cycle) and forming cadence are therefore different meters-per-minute numbers on the same flow sheet.

Industry cable-tray guides often list continuous forming in one band and punch cadence in another — the same reading discipline applies when using trough FAQ speed notes.

2. Reference speed bands (100–600 mid width)

Do not average these bands into one catalogue “line speed.”

3. Other trough tiers (do not merge)

4. How to read a proposal

1. Ask which number is forming host speed vs punch-station production speed.
2. Confirm pre-cut vs post-cut layout — pre-cut makes the punch band more visible.
3. Keep Egypt or other market feed ranges labeled as feed, not as forming.
4. Power and stand counts follow the same width tier; do not import BIG or perforated kW.

5. Buyer FAQ

Is punch 2–4 m/min the same as forming 3–6?

No. On pre-cut mid-width references they are separate cadences on one line.

Can I quote BIG punch 3–8 as the 100–600 answer?

No. Keep width tiers side by side.

Does 0–20 m/min mean the host forms that fast?

Not from the Egypt note alone — that band is uncoiler feed language in the FAQ.

6. Verification notes

• Publish only numbers that appear on the named FAQ / parameter sheet for this leaf.
• When two source documents disagree, list both tiers with labels — do not average.
• Host ratings stay separate from auxiliaries (curving, stacking, offline presses) unless the FAQ bundles them.
• Directory identity is fixed; open fields stay blocked until a proposal confirms them.
