Why we organize moulds by refrigerator cabinet type, not by mould technology
Most mould suppliers list their catalog by "vacuum forming mould / foaming mould / door mould" — the way the mould works. We list ours by "chest freezer / cake cabinet / chef base / island freezer / kitchen refrigerator / display cabinet" — the cabinet you sell. That's on purpose.
Buyer mental model
Refrigerator factories don't buy "a foaming mould" — they buy "a mould that makes my 350L chest freezer". The cabinet drives every dimension; the mould technology is a means to an end.
One-stop cabinet → mould match
When a buyer sends us a cabinet drawing, we map it to one of the six families in 30 minutes. The right mould is the one designed around that cabinet family, not a generic one we adapt.
Template library depth
Across the six families, we have hundreds of cavity templates accumulated over 30 years. Your "new" cabinet design probably maps to a template within 2–5% — which means a 45-day mould instead of an 80-day mould.
Whole-line fit
Each family carries its own optimal foaming machine spec, fixture clamping force, and PU recipe density. When you buy the mould, you also get a complete recommendation for the rest of the foaming line.

Cast aluminium ZL105 / LY12 — why this material wins for refrigerator moulds
Some mould suppliers use steel, others use forged aluminium. We use cast aluminium ZL105 with LY12 reinforcement. Here's the engineering reasoning.
Thermal conductivity
Thermal conductivity ~150 W/m·K — four times better than P20 steel. Heat transfers fast and evenly across the cavity, which keeps foam cure consistency tight and lets you run shorter cycles.
Machinability
Aluminium machines fast on CNC. We hold ±0.05 mm cavity precision routinely, with a 3-axis CNC mill — steel cavities of the same geometry need a 5-axis machine and 2× the machining time.
Weight
Half the density of steel. A 2.5 m island freezer mould weighs ~1,800 kg in cast aluminium vs ~5,500 kg in steel. Easier handling on the fixture, cheaper transport, less stress on the lifting drive.
Cost balance
Aluminium itself is more expensive per kg than mild steel, but the machining and handling savings net out cheaper for refrigerator cabinets. Steel is still cheaper for shapes that don't need precision (frame structures, fixture columns), so we use Q235 steel there.
The trade-off
The trade-off: aluminium dents if you drop it. Operator handling discipline matters — we ship every mould with a handling/maintenance manual and train your team during commissioning.
How we engineer the cavity — geometry, cooling, venting
The "mould" is really three things wrapped into one: the cavity that shapes the foam, the cooling channels that pull heat out, and the gates/vents that control how the foam flows in and air flows out. We design each one around your specific cabinet.
- 1
Cavity design — start from cabinet CAD
Your cabinet DWG / STEP / IGES file goes in. We back-engineer the cavity geometry with 1.5–2 mm draft angles where needed, accounting for foam shrinkage during cure (~0.3% linear for refrigerator-grade PU).
- 2
Cooling channel layout — even heat extraction
Channels run 15–25 mm below the cavity surface, spaced 80–120 mm apart. We CFD-simulate water flow to ensure no hot spots (which cause foam over-cure) or cold spots (which cause under-cure). Channels are red copper for thermal conductivity.
- 3
Gate and vent placement — control the foam flow
For most refrigerator cabinets, one gate at the bottom-center plus 3–6 vents at the cabinet top corners. For long cabinets (island freezer, kitchen refrigerator), we use a single gun head, one-end horizontal filling — the foam flows uniformly from one end, vents push air out the other end, no trapped pockets.
- 4
Mounting and fixture interface
Mould bolts to our refrigerator mold fixture (catalog §04) at standard 8-point or 12-point bolt patterns. For non-standard fixtures, we fabricate adapter plates in 7–10 days.
Curing time, mould temperature, and PU recipe — how they connect
Most "my cycle is too slow" complaints trace back to one of three settings: mould temperature, PU recipe gel time, or cooling channel coverage. Here's how we tune them.
| Cabinet type | Mould temp | PU gel time | Demould cycle |
|---|---|---|---|
| Chest freezer (220–800L) | 45–55°C | 40–60s | 6–10 min |
| Cake / display cabinet | 45–55°C | 35–50s | 6–15 min |
| Refrigerated workbench (2–4 door) | 45–55°C | 50–70s | 8–20 min |
| Island freezer (2–3 m) | 50–55°C | 70–90s | 12–20 min |
| Kitchen refrigerator (4–6 door) | 50–55°C | 60–80s | 12–20 min |
| Glass-door display cabinet | 45–55°C | 35–50s | 6–15 min |
If you want a faster cycle, the first lever is mould temp (push from 45°C toward 55°C — gains 20–30% on cure time). Second lever is the PU recipe (faster amine catalyst — gains another 20–40%). Third lever is the cooling layout (which we may need to redesign if it's been bolted on as an afterthought).
How the mould pairs with the rest of the foaming line
A mould doesn't work in isolation. The matched setup is mould + fixture + foaming machine + PU recipe. We can supply all four — or one, or any subset — but here's how they fit together.
The mould bolts to a refrigerator mold fixture (catalog §04). The fixture clamps the mould halves at 1–5 tons, heats the platen to 30–70°C, and lifts/lowers between cycles. Our fixture is mounting-compatible with all six mould models.
View product →PU is injected through the gate by either a high-pressure cyclopentane machine (energy-class A++/A+++ refrigerators) or a low-pressure machine (small cabinets like wine cabinet variants). The catalog §05 PU machines have already been calibrated against these moulds.
View product →The PU recipe lives in the §05 raw materials catalog. The recipe family (cyclopentane high-pressure / HFC-245fa standard / HFO low-GWP) is chosen by the cabinet's target market and energy class. We pre-tune the recipe to the mould geometry and the fixture's heated platen profile.
View product →When all four come from us, you have one supplier accountable for foam quality. When something's off, we can't pass blame between mould, fixture, machine and chemicals — and you don't have to mediate between four vendors.
Customization capability — your cabinet, our mould
Every mould we ship is customized to your specific cabinet drawing. We don't sell off-the-shelf moulds — but we don't start from scratch either. Here's what we customize and how.
Cabinet geometry & size
Cabinet shape & dimensions — start from your DWG / STEP / IGES file. Custom cavity geometry from 120 L household up to 800 L commercial cabinet. Curved-glass front, faceted body, multi-door layouts all supported.
Cavity count per mould
Cavity count per mould — 1-cavity (R&D / small batch) / 2-cavity (300–800 units/day) / 4-cavity (1,000+ units/day). Higher cavity counts increase mould capex but cut per-cabinet cycle time.
Fixture interface
Mounting bolt pattern — standard 8-point or 12-point that matches our refrigerator mold fixture (catalog §04). Non-standard fixtures: we fabricate adapter plates in 7–10 days.
Cooling scheme
Cooling channel layout — water-cooled (standard, fast cycle) or air-cooled (rare, only for low-density polyols). Channel depth, spacing and routing tuned to your cabinet thermal profile.
Surface finish
Cavity surface finish — CNC + manual polish standard. Mirror-polish (for premium home refrigerator brands) or matte-sandblast (for textured commercial cabinets) on request.
Brand marking
Optional engraving on cabinet inner surface — your brand logo / serial number / production date marker embedded in mould cavity (preferred over post-print decals for premium positioning).
Mould manufacturing process — 45-80 day timeline, in-house quality control
From your cabinet drawing to a packed mould in our shipping container. 7 stages, in-house CNC + heat treatment + polishing — no subcontracting.

Lead time, commissioning, service, lifespan
A refrigerator mould is a 5–10-year piece of capital equipment. Here's what to expect on the timeline and what we cover.
Lead time
45–80 days from design freeze to shipment, depending on cabinet size and complexity. First-time orders that include co-design add 1–2 weeks for cabinet review.
Commissioning
Engineer team on-site for 3–5 days when the mould arrives — first-shot setup, gate/vent tuning, first 20–50 trial cabinets, parameter card hand-over. Travel and lodging on us for orders over USD 50K.
Warranty
12 months on cavity integrity (excludes operator handling damage like drops). 24 months on supporting frame and bracket structure. Remote diagnostics free for the first 12 months.
Spare parts
We stock cavity inserts, gaskets, gate bushings and water-pipe fittings as routine wear items. Most parts ship from Shanghai, Istanbul or Dammam in 2–5 days.
Mid-life refurbishment
After 500K–1M cycles, the cavity surface degrades enough to need refurbishment (re-polishing, channel cleaning, gasket replacement) — typically 20–30% of new mould price. Adds another full life.
Full replacement triggers
Full replacement is usually triggered by SKU changeover (new cabinet design) rather than wear-out — most refrigerator factories rotate moulds across 3–8 cabinet SKUs over a 10-year window.
