PU Foaming Line for Insulation Box Production — 10-to-600 L Box Capability
PU foaming module (machine + jigs + recipe + commissioning) for factory owners building insulated cold-chain transport boxes. Wall 30–80 mm PU, k=0.022–0.024 W/m·K. Vaccine WHO PQS-recipe-ready, fresh-food, seafood, pharma applications covered.
Scope note: What we supply = PU foaming machine + jigs (工位) + raw-material recipe + commissioning. What's NOT in our scope = vacuum-forming of inner/outer plastic shells, final assembly (handles, latches, gasket, lid, brand printing), final QC. You source these separately — we hand you the reference BOM at quote time.

PU Foaming Process (per jig position)
Our equipment scope — what one jig (工位) runs per cycle. Throughput per jig = 3,600 ÷ cycle-seconds × shift-hours × OEE.
- Clamp jig closed — operator loads pre-assembled inner liner + outer shell (sourced from your vacuum-forming step) into the jig with a 30–80 mm foam cavity.
- PU injection — low-pressure or high-pressure machine shoots POL + Cyclopentane + ISO through the gate. Cream 6–10 s, gel 30–60 s.
- Cure — foam expands and cross-links inside the cavity. Demould window 60–180 seconds depending on wall thickness and ambient.
- Demould — open jig, lift the foamed box body out.
- Trim + reset — trim gate excess, surface-inspect, reset jig for next shot. 1–2% reject rate typical.
Out of our scope: vacuum-forming HIPS/ABS shells (upstream), final assembly (handles/latches/gasket/lid/brand printing), final QC, packaging. Your factory sources these separately — we hand you a vetted BOM at quote time.
Temperature Tier Coverage
- Tier 1 Chilled (+2 to +8°C): 40 kg/m³ foam, 30–50 mm wall, 24–72h cold-life — pharma fridge / meal-kit / fresh produce
- Tier 2 Frozen (−18 to −25°C): 42 kg/m³, 50–80 mm wall, 48–96h — seafood / ice-cream / frozen meals
- Tier 3 Deep-frozen (−40 to −60°C): 45 kg/m³ + heated gasket, 80–120 mm wall, 96–160h — plasma / clinical trial / sashimi-grade
- Tier 4 Ultra-low (−70 to −86°C): PU+VIP hybrid composite k≤0.005, ≥150 mm wall, 120–168h with dry ice — mRNA vaccines / biorepository / ULT shipping
Certification Path Support — what we cover vs what's yours
Our scope: PU recipe + jig design to meet the thermal performance the cert demands. Your scope: lab submission, application paperwork, factory audit, listing maintenance.
- WHO PQS E004/QA01 (cold boxes) + E004/SD01 (shipping containers) — vaccine cold-chain procurement by WHO/UNICEF/Gavi. Our part: PU recipe + jig design tuned for 5–7 day cold-life at 43°C. Your part: lab submission to Intertek/SGS/TÜV (8–12 weeks), WHO application paperwork, factory audit. Total cert cost USD 25K–50K, year-1 tender ROI typically 3–5×.
- ISTA 7E (Temperature Test for Transport Packaging) — required by major pharma + meal-kit + e-commerce. Thermal profile validation + drop test + vibration.
- ASTM D3103 (Thermal Insulation) — North American thermal performance standard.
- USP <659> (Packaging and Storage Requirements) — pharmaceutical packaging compliance.
- GDP (Good Distribution Practice) — EU pharma distribution requirement.
- IATA Temperature Control Regulations — air freight cold-chain compliance.
