1. Definition
A rockwool / EPS composite panel line produces insulated sandwich panels with rockwool or EPS cores. Inside this family, PU-edge continuous and glue composite are configurations — not two unrelated catalog names that may silently share one speed/power table.
A PU full-core continuous foaming line (polyurethane fills the entire core) remains a different machine class.
2. Process and applications
2.1 Typical PU-edge continuous path
- Uncoiling, front shear, film, rib rolling
- Upper and lower roll forming
- Rockwool conveying and adhesive spray
- PU edge foaming (low-pressure foaming machine on the scheme)
- Roll laminator curing
- Side chain, flying saw, and product support
2.2 Glue configuration path
Uncoiling → top-sheet roll forming → glue spray / infrared heating with bottom sheet and core boards (often manual feed) → flying saw → product tables. See the dedicated glue-configuration page for that tier’s numbers.
Applications. Roof and wall panels that need mineral-wool or EPS cores; PU-edge when sealed edges and continuous rockwool feed are required. Fire / insulation performance follows contract tests.
3. Reference parameters by configuration (do not mix rows)
3.1 PU-edge continuous (recommended Chinese technical scheme)
| Item | Documented reference |
|---|---|
| Normal / max speed | Normal about 3–5 m/min; design max about 8 m/min |
| Whole-line power | About 90 kW class (subunit motors may be ~10 kW class — cite config table) |
| Skin / core / width / length | Skin about 0.4–0.6 mm; core about 50–100 mm; effective width about 1000 mm; length about 3000–15000 mm |
| Coil | Max about 5 t; width max about 1250 mm; ID about ø508 |
| Edge foam note | Rigid foam density about 45±5 kg/m³; foam pressure max about 0.3 kg/cm² (units per contract drawing) |
| Footprint | Minimum about 80 m × 10 m or larger; roll laminator about 10 m; operation height about 1200 mm |
| Supply | About 380 V × 50 Hz; PLC brand not locked on the scheme |
3.2 Glue composite (same family — separate ratings)
| Item | Documented reference |
|---|---|
| Composite speed | About 5 m/min (short-table alternate about 0–4 m/min) |
| Total power | About 50 kW class (short-table alternate about 28 kW) |
| Panel thickness | About 50–250 mm per requirement |
| Core feed | EPS or rockwool boards — often manual |
4. Boundaries
- PU full-core continuous foaming — Best about 4 m/min; installed about 40 kW (+ optional heat about 90 kW). Do not paste those figures into this composite answer.
- Belt hard-foam PU variant — About 2–6 m/min; ≥35 kW. Different PU configuration.
- Do not use glue ~50 kW as a silent substitute for PU-edge ~90 kW (or the reverse).
- Do not copy pure PU / EPS glue BOMs onto a PU-edge equipment list without re-checking units.
5. Buyer FAQ
Are PU-edge and glue two unrelated machines?
They are configurations of the same rockwool/EPS composite family. Still use separate speed/power tables.
Is this the same as a full PU foam continuous line?
No. Here the core is rockwool or EPS board; PU is used for edge sealing (PU-edge) or not at all (glue).
What speed and power should I quote for PU-edge?
Normal about 3–5 m/min; design max about 8 m/min; whole-line about 90 kW class — not a single subunit motor alone.
Where are glue 5 m/min / 50 kW details?
On the dedicated glue-configuration encyclopedia page. Do not average them with the PU-edge row above.
Final ratings follow the confirmed configuration proposal. Price and lead time are out of scope.
