Material Preparation, Metering and Laydown
Five-component PU/PIR metering for sandwich panels, with independent polyol, isocyanate, catalyst and blowing-agent circuits, flow monitoring and line integration.
The HF-HPC-50-CS reference is a five-component high-pressure polyurethane metering and mixing system for metal-faced PU/PIR sandwich panel production. Separate circuits meter polyol, isocyanate, two catalysts and a pentane blowing-agent stream. Component flow feedback, material conditioning and circulation are coordinated with the selected formulation and production line.
The supplied reference specifies 19–30 kg/min injection output and an adjustable injection-pressure range of 6–20 MPa. The metering package can work with a stationary or traversing laydown head, while refill equipment and heating/cooling units maintain material supply. Output must be sized against panel width, thickness, foam density and line speed.
Pentane handling uses a separately specified enclosure, gas monitoring, ventilation and interlock scope. Material-tank volumes, mixing-head model and utility loads are finalized in the configuration schedule.

Metering and Integration Functions
Five Independent Component Circuits
Polyol, isocyanate, two catalysts and blowing agent have individually specified metering and feed paths.
Component Flow Feedback
Flow signals coordinate pump delivery with the selected recipe, while component tests provide calibration references.
Material Conditioning and Refill
Tank conditioning, level indication and refill equipment support continuous component availability.
Circulation and Head Coordination
High/low-pressure circulation switching and mixing-head operation follow the PLC injection sequence.
Line Laydown Interface
Stationary and traversing head arrangements are sized for the facing-sheet width, shot requirement and production speed.
Blowing-Agent Monitoring Interfaces
Pentane metering, enclosure ventilation, gas monitoring and stop/interlock actions are specified together in the project scope.
