Applications

Household 2-door / French-door / side-by-side refrigerator door — crawler line
Commercial multi-door refrigerator door — 16-station crawler output
Chest freezer lid — crawler chain conveyor mid-volume
Glass-door display cabinet door — mid-volume OEM crawler output
  • Mid-to-large refrigerator OEM door factory (1,500–2,500 doors/shift)
  • French-door / side-by-side / 4-door refrigerator door mix
  • Compact factory hall where ground-rail 26-station loop is too large
  • Commercial display cabinet door foaming (multi-variant chain mix)
  • Door-specialty workshop feeding multiple cabinet assembly lines

The 16-station crawler door foaming line is the mid-volume sibling to the 26-station ground-rail loop. Chain-conveyor moves door fixtures through 16 heated curing stations, with throughput tuned for 1,500–2,500 doors/shift. Best fit: refrigerator OEM factories making 600,000 – 1.5M doors/year — too high for rotary 7/8-station, too low to justify ground-rail 26-station capex.

When 16-station crawler beats both rotary and ground-rail

Pick 16-station crawler when (a) your daily door demand is 1,500–2,500 (rotary 7/8 maxes at 1,000, ground-rail wastes 30%+ capacity), (b) your factory hall is 15–20 m long (rotary hub fits 6m, ground-rail needs 30m), (c) you run a 2–4 SKU door mix (crawler chain accepts more variant changes than ground-rail closed loop).

Why the 16-station crawler wins on mid-volume door production

Engineering and capex advantages over rotary 7/8 and ground-rail 26-station alternatives.

#1

Capacity sweet spot 1,500–2,500 doors/shift fills the rotary-to-ground-rail gap

Rotary 7/8: 600–1,000 doors/shift. Ground-rail 26: 3,000–6,000 doors/shift. The 16-station crawler at 1,500–2,500 covers the underserved mid-volume range where most refrigerator OEM factories actually operate (600K – 1.5M doors/year).

#2

Compact 17 × 2.5 × 2 m footprint — half the ground-rail envelope

Ground-rail 26-station: 230 m² floor envelope (29 × 8 m). Crawler 16-station: 42 m² floor (17 × 2.5 m). Fits factory halls where ground-rail won't — 80% of mid-size OEM factories globally.

#3

30-second cycle keeps pace with downstream cabinet assembly

Cabinet assembly lines typically run 30–40 sec/cabinet. A 30-sec crawler door cycle matches assembly pace 1:1 — no door buffer needed, no bottleneck. Rotary 46-sec cycle creates buffer; ground-rail 20-sec cycle outpaces assembly.

#4

Chain conveyor accepts 4–6 variant SKU mix without full changeover

Crawler chain stations accept multiple door variants simultaneously (each fixture position runs independent PLC recipe). Rotary single-station-at-a-time changeover wastes 8–15 minutes per SKU switch. Crawler runs continuous mixed batch.

How the 16-station crawler cycle runs

30-second station-to-station cycle. Each door spends ~8 minutes total in line (15 sec inject + 7.5 min cure across 15 stations + 30 sec demould).

  1. 1

    Station 1 (Load) — 2 operators load pre-skinned door panels onto fixture trays riding the chain conveyor. Multiple SKUs can load in parallel onto different positions. ~25 sec per station feed.

  2. 2

    Station 1 (Inject) — pneumatic clamp engages, PU mix-head injects POL+ISO+cyclopentane (1.0–1.8 kg per door). ~15 sec.

  3. 3

    Stations 2–15 (Cure on chain) — chain conveyor carries fixtures through 14 heated curing stations. Water-circulated platens maintain 45–55°C. Foam rises and cures. ~7.5 minutes total (30 sec × 15 stations).

  4. 4

    Station 16 (Demould) — pneumatic clamp releases, operator lifts cured door onto take-off conveyor. ~25 sec.

  5. 5

    Downstream feed — completed doors enter gasket-fitment / hinge-mounting / final assembly. Cabinet assembly line consumes doors at matching 30-sec rate. ~10 sec transit.

FAQs — 16-station crawler door foaming line

Investment + lead time?
USD 580K–820K turnkey, 120–180 days lead time. Includes 16-station chain crawler fixture, 16 fixture template sets (one cabinet door variant), water-heated platens per station, cyclopentane-spec PU machine + ATEX safety, on-site commissioning + 7 days training.
Operators per shift?
3–4 operators per shift: 2 at load station (loading door variants onto chain), 1 PU machine operator, 1 at demould + QC. Plus 1 maintenance technician shared across multiple lines.
Can it run alongside an existing rotary 7/8 line?
Yes — common configuration for OEM factories scaling up from rotary 7/8 (capped at 1,000 doors/shift) to mid-volume. Rotary handles small-variant or specialty SKUs; crawler 16-station handles main-volume household 2-door / French-door variants.
What door panel sizes fit?
Fixture template: 1,400 × 900 mm standard. Accommodates household 2-door (1,200 × 700 mm), French-door panels (1,400 × 700 mm), side-by-side commercial display doors. Larger 2 m+ door panels need fixture upgrade (+USD 45K–80K, 45 days).
How does cycle time compare to rotary 7/8?
Crawler 30 sec/door vs rotary 46 sec/door — 35% faster cycle. Multiplied by 16 stations vs 7/8 stations: throughput 2,000–2,500 vs 600–1,000 doors/shift. Per-door capex is similar (USD 300–500 per door/year capacity). Crawler wins on absolute volume, rotary on small-batch + variant changeover flexibility.
When NOT to use 16-station crawler?
Below 1,500 doors/shift demand → rotary 7/8 or 6-station servo delivers required capacity at 35–50% lower capex. Above 2,500 doors/shift → ground-rail 26-station throughput-per-dollar wins. Above 4 SKU mix with sub-mm precision needs → 6-station servo precision beats crawler ±0.3 mm.
