Material conditioning, multi-head metering, vertical clamping fixture and synchronized controls. Shell geometry, molds, blowing-agent system, exhaust and site interfaces are agreed separately.
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.

Material Flow and Working Principle
Sheet Positioning & Vertical Mold Clamping
Exterior corrugated stainless steel sheets and interior food-grade lining skins are loaded into the vertical press bed; hydraulic toggle locks clamp the 13.5m platens under 1.2 bar counter-pressure.
High-Pressure Chemical Conditioning
Specialized low-k polyol blends and polymeric isocyanates are conditioned in dual 500 L jacketed day tanks at 24°C ± 0.5°C under dry nitrogen blankets to maintain reaction kinetics.
Synchronous 6-Head Impingement Injection
High-displacement axial piston pumps displace chemicals at 17.0 MPa through six synchronized impingement mixing heads along the panel base, injecting 110 kg of formulation within 25 seconds.
Vertical Rising Core Expansion & Curing
The liquid matrix creams rapidly, rising vertically through the 70 mm core gap; precision water-heated platens maintain 48°C to cure the panel within 20 minutes without density gradients.
Vertical Mold Opening & Overhead Extraction
Hydraulic cylinders retract the vertical clamping platens; automated overhead cranes grip the finished 12-meter monolithic panel and transfer it to container box assembly.
