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.

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).

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.

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.

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

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

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

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