Applications
- Sample / pilot door foaming for new cabinet variants
- Low-volume premium refrigerator door (small batch certified)
- R&D / prototype door foaming (variant verification before main line)
- Trial production of new door materials / formulations
- Workshops with <500 doors/shift demand
The manual rotary 4-station door foaming specialty machine is the R&D / pilot / sample-run equivalent for door production. Same principle as the single-station cabinet machine: same fixture template as production lines, but one cycle at a time with manual rotation. Use it for new door design verification, low-volume premium variants, or as a cost-effective entry into refrigerator door production.
When manual 4-station door specialty makes sense
Buy this machine when (a) your daily door demand is < 500 (any production line is over-investment), (b) you're verifying new door designs before committing to full line tooling, (c) you produce premium / R&D variants in small batches where unit cost matters less than time-to-market. Many refrigerator OEM factories use this for prototype work + main line for volume.
Four reasons manual 4-station beats automated lines for R&D / pilot door work
Engineering and economics of the manual specialty configuration.
Capex USD 60K–120K — 1/8 of a 6-station servo line
6-station servo line: USD 480K–720K. Manual 4-station specialty: USD 60K–120K turnkey. For R&D / pilot / specialty work where unit throughput is secondary, the manual is the right capex sizing.
Same fixture template as production lines — direct trial-to-production path
The 1,400 × 900 × 200 mm fixture matches the 16-station crawler line exactly. A door design verified on the manual goes straight to crawler tooling — no re-engineering. R&D cycle shortens 4–8 weeks vs trialing on incompatible smaller fixtures.
Capacity 150–400 doors/shift covers small-batch + variant trial
Manual cycle ~90 seconds per door = ~320 doors/shift theoretical, 150–400 realistic with variant changes. Handles R&D pilot batches, premium specialty SKUs, and low-volume certified doors (vaccine / pharma refrigerator).
Lower operator skill requirement — manual = easier training
No PLC recipe management, no servo calibration, no high-pressure hydraulics. 1 operator + 1 PU machine operator. New operator productive within 2–3 days. Servo / crawler lines need 5–7 days training + ongoing PLC literacy.
How the manual 4-station rotary cycle runs
90-second cycle per door. 4 stations rotate manually with hydraulic clamping at each station.
- 1
Station 1 (Load) — operator loads pre-skinned door panel + inner liner onto fixture position 1. Manual position-check with reference marks. ~30 sec.
- 2
Station 1 (Clamp + Inject) — operator engages hydraulic clamp via foot-pedal. PU mix-head dispenses POL+ISO+cyclopentane (0.7–1.4 kg/door). ~20 sec.
- 3
Rotate to Station 2 — operator manually rotates hub 90° to advance the door to station 2 for curing. ~5 sec rotation.
- 4
Stations 2–4 (Manual cure rotation) — door cures in heated fixture (water-jacket 45–55°C) for ~3.5 minutes across 3 stations. Operator works on next door in parallel. ~210 sec.
- 5
Station 4 (Demould) — operator releases clamp, lifts cured door onto outfeed cart. Spot-check density before downstream. ~25 sec.
