Garage Door Continuous Foaming Panel Production Line
Table of Contents
1. Definition
A garage door continuous foaming panel line produces garage door sandwich panels: metal skins with a polyurethane foam core cured under a double-belt press, then cut to length with a flying saw. The core of the line is continuous wide-panel foaming and curing — not simple shutter-slat roll forming and hydraulic cut-off.
Industry continuous PU panel descriptions (uncoil → form → preheat → foam → double belt → tracking cut) match the same architecture used for garage door panels, with garage-specific width and thickness bands.
2. Applications
- Residential sectional garage door sandwich panels
- Commercial / light industrial overhead door insulated panels
- Plants that need continuous foamed panels rather than interlocking roller-shutter curtain slats
3. Documented ranges
| Item | Reference (garage continuous line) |
|---|---|
| Plant speed | Max about 10 m/min; min about 2.5 m/min; typical about 4–6 m/min (depends on foaming and cutting) |
| Panel width | About 510–600 mm |
| Finished foam thickness | About 40–60 mm |
| Double belt | About 24 m; often with side-chain support |
| Overall line length | About 85 m |
| Controls | PLC commonly cited (Panasonic on the reference quote) |
| Forming main motor total | Not unified on the reference quote — pending proposal confirmation |
| Steel skin thickness | Often “to be specified” — do not publish one fixed public value |
Typical unit list: dual uncoilers, embosser, press/punch (by configuration), upper/lower formers, preheat, high-pressure foaming, double belt, thickness tooling, flying saw, electrical/hydraulic systems. Exact BOM follows the technical proposal.
4. Boundaries
- Not a standard roller shutter slat line (including PU shutter-slat setups).
- Not a door frame line and not a guide/slide line.
- Do not publish shutter-slat speed bands (for example about 8–10 m/min PU slat references) as garage plant speed.
- Do not invent a single forming-main kW or skin thickness when the source left them open.
5. Buyer FAQ
Is this the same as a PU shutter slat machine?
No. Both may use polyurethane foam, but garage lines make wide sandwich panels with double-belt curing; PU shutter lines make narrow interlocking curtain slats. See the dedicated comparison entry.
What speed should we put in a brochure?
Use the garage band: about 2.5–10 m/min with typical about 4–6 m/min, and note dependence on foaming and cutting.
Why is main motor power missing?
The reference quotation does not give a single forming-main kW total. Mark pending confirmation on the technical proposal rather than inventing a number.
What floor space should we plan?
Reference overall length about 85 m with a double belt about 24 m — confirm layout against the final BOM and utilities.
Ratings follow the confirmed technical proposal. Price and lead time are out of scope.
