High-Pressure PU Foaming Machine for Sandwich Panels

Product Overview

Specially designed for continuous foaming production of building exterior wall insulation panels, clean panels and prefabricated building sandwich panels.

The HF-HPM-2A2B-SandwichPanel is a two-component PU metering reference with a 2A2B tank arrangement, material conditioning, circulation and PLC control. Listed pressure is 10–18 MPa and flow is 300–2,200 g/s. Match actual flow, formulation, mixing-head configuration and laydown arrangement to panel duty. Cell structure, conductivity and compression strength require panel tests.

Operation Workflow

Raw Material Preparation

Prepare polyether polyol and isocyanate at the target mix ratio (100:100-130) for rigid foam insulation, with proper conditioning for uniform cell formation.

Tank Loading & Temperature Setting

Load polyol into Tank A and isocyanate into Tank B; the 2A2B temperature control maintains 20-45°C with circulation stirring for consistent material quality.

High-Pressure Mixing & Large-Flow Pouring

Calibrate the two-component delivery for the selected material. Listed mixing pressure is 10–18 MPa and flow is 300–2,200 g/s; head selection, cell structure and panel properties are validated separately.

Continuous Panel Foaming & Face Composite

Continuously pour foam between color steel or aluminum foil face materials; full-line linkage enables quick switching of multi-specification, multi-thickness panel production.

Frequently Asked Questions

What sandwich panel applications is this equipment designed for?
This equipment is specially designed for continuous foaming production of building exterior wall insulation panels, clean panels, and prefabricated building sandwich panels, suitable for composite of color steel, aluminum foil and other face materials.
What is the advantage of the large-flow pouring capability?
The pouring rate of 300–2200 g/s is ideally suited for panel continuous production lines, greatly improving foaming efficiency and production capacity compared to traditional equipment.
How does the equipment ensure panel insulation quality?
Select the recipe, dosing flow, ratio, head and cure conditions together. Test cell structure, conductivity and compression strength on the actual finished panel.
What is the dosing accuracy and why is it important?
The dosing accuracy is ≤±0.3% across the full dynamic range. This precise ratio control minimizes raw material loss and ensures consistent product quality for large-scale continuous production.
Can the equipment handle different panel specifications?
Yes. Full-line linkage control enables quick switching of production of multi-specification and multi-thickness panels, providing flexibility for diverse building material requirements.
What certifications does this equipment hold?
Documentation and conformity requirements are reviewed for the selected equipment configuration and destination market. Request the applicable declarations and supporting records for the quoted model. A company quality-management certificate does not certify the equipment or finished-part performance.
