Station Map — 26-Station Closed Loop
The ground rail circuit is divided into four functional zones. Cabinets move on rail-mounted fixtures, dwelling at each station for the 20-second tact.
| Zone | Stations | Purpose |
|---|---|---|
| Loading & Mould Closing | 1–3 | Cabinet-in-mould pre-positioning; mould halves close at clamping pressure 5–50 t |
| PU Injection | 4–7 | Polyol + ISO + Cyclopentane shot via high-pressure mixing head; precision ±0.5% |
| Cure (heated rail) | 8–22 | 15 stations × 20 s = 5 min cure dwell at 40–55 °C platen |
| Mould Opening & Unload | 23–26 | Demould, cabinet to next-stage conveyor, fixture return |
Paired Equipment (Sold Separately or as Turnkey)
- Vacuum-forming mould station — ABS / HIPS liner production, ±0.05 mm cavity precision (see UREXCEED moulds catalog)
