Typical Silo Panel Line Process Flow

1. Sequence (economic type)

1. Coil load / decoil (manual feed class)
2. Entry calibrate / guide
3. Optional front cut
4. Roll form corrugation
5. Transverse full-row punch (stop)
6. Servo move punch (one hole per move, longitudinal)
7. Post-form die cut to length
8. Exit / support table

Public silo-panel flow charts often show decoil → level → form → punch → cut → curve. The economic reference keeps punch after form in two modes (bank + servo) and treats curving as a separate machine when the project needs arc panels.

2. Line units

• Manual feed / decoil
• Drive, roll stands, and main host
• Punching devices (transverse bank + servo move)
• Cut-off, hydraulic station, PLC/controls
• Finished-panel support

3. Punching modes

Flying / tracking punch layouts appear on other market configurations — confirm on the named proposal before assuming continuous punch.

4. Curving note

Three-roll curving is an auxiliary after panels are formed. Do not replace host process speed (economic ~15 m/min class) with curving cycle time, and do not fold curving drive kW into the forming-main answer without saying so.

5. Variant caution

HY1250 arc type, 68×13 heavy, and wall-panel update notes change speed, power, and thickness. Keep those process pages or proposals separate from this economic flow map.

6. Inquiry checklist

• Hole map (transverse rows + longitudinal pitch)
• Whether front cut is required
• Punch mode preference (bank / servo / flying)
• Curving yes/no and silo diameter
• Economic vs heavy tier before discussing m/min

7. Buyer FAQ

Is flying punch the economic default?

The economic reference uses stop bank punch plus servo move punch after forming. Flying/tracking punch layouts belong to other market configurations — confirm on the named proposal.

Where does HY1250 / heavy 68×13 differ?

Speed, power, and thickness bands change by variant. Keep those process pages or proposals separate from this economic flow.

Is curving step 9 on the main line?

Only if the contract includes a curving machine. Otherwise the flow ends at cut and exit support.

Where do speed and kW live?

On the economic equipment entry (and sibling variant pages) — this page is a process map only.
