40ft Reefer Container Foaming Solution
Six-head PU delivery and vertical fixture control for long reefer-container sidewalls, with part-specific fill and curing sequences.
Monolithic Thermal Integrity for 40ft Global Intermodal Reefer Containers
Six-head PU delivery and vertical fixture control for long reefer-container sidewalls, with part-specific fill and curing sequences.
Equipment and process scope
Material conditioning, multi-head metering, vertical clamping fixture and synchronized controls. Shell geometry, molds, blowing-agent system, exhaust and site interfaces are agreed separately.
Validation and production planning
A 110 kg shot in 23.5 s implies 280.9 kg/min, exceeding the stated combined 240 kg/min maximum. Reconcile output, shot mass and actual injection duration. Whole-container heat transmission is a finished-assembly test, not the material conductivity or machine rating; ATP-related claims need original assembly reports.

Sheet Loading & 13.5m Vertical Clamping
Supplied process reference: Corrugated stainless exterior skins and interior liners are loaded into the vertical press; hydraulic toggles clamp the bed under 1.2 bar counter-pressure.
Sealed Nitrogen Conditioning & Metering
Supplied process reference: Cyclopentane-polyol and polymeric isocyanates are conditioned in dual 500 L tanks at 24°C under dry nitrogen blankets, metered by servo axial piston pumps.
Six-Head Synchronous Base Injection
Supplied process reference: Six high-pressure impingement heads discharge simultaneously along the tool base, injecting 110 kg of formulation within 25 seconds at 220 kg/min.

Core Advantages of Haifeng Reefer Systems
Configured equipment functions and interfaces for the selected material and tooling.
ATP reported U ≤ 0.32 W/(m²·K)
Supplied configuration function: Monolithic 12.2-meter seamless construction eliminates splicing cold bridges, meeting global perishable transport rules. Project-dependent performance requires validation.
1.2 Bar Anti-Bulging Clamping
Supplied configuration function: Heavy vertical hydraulic structure withstands 1.2 bar expansion force, keeping wall thicknesses within ±0.5 mm. Project-dependent performance requires validation.
25-Second Rapid 110 kg Shot
Supplied configuration function: Six synchronized base heads flood cavities in 25 seconds, eliminating vertical density gradients. Project-dependent performance requires validation.
Natural Vertical Air Venting
Supplied configuration function: Vertical rising expansion purges air upward naturally, aims to reduce horizontal core air pockets. Project-dependent performance requires validation.
