Product Overview
The HF‑CLPS‑Continuous is a fully‑automated continuous PU panel line with stepless speed control, delivering uniform rigid foam for building, cold storage & prefab applications.
The HF-CLPS-Continuous is a fully-automated continuous PU sandwich panel line for high-volume production of insulation panels for building walls, cold storage, clean workshops, and prefabricated buildings. It supports color steel, aluminum foil, and paper honeycomb facings, meeting requirements for uniform density, insulation, flame retardancy, and dimensional accuracy. The system features independent temperature-controlled tanks (200L/300L) with two-component temperature management (20–45℃), a high-pressure mixing head (10–18 MPa) with ≤±0.3% metering accuracy, and PLC-based full-line linkage control. Line speed is continuously adjustable from 1 to 15 m/min, enabling rapid switching between panel thicknesses (30–200 mm). Precise roller/mold temperature control ensures optimal curing, while solvent-free automatic circulation and air purge cleaning reduces maintenance and chemical waste. This line boosts production efficiency while maintaining consistent quality across large-scale operations.
Production Workflow
Continuous Lamination & Conveying
Feed top and bottom facing materials (color steel, aluminum foil, etc.) into the continuous laminator; set line speed (1‑15 m/min) per panel thickness and cure requirements.
Recipe Selection & Ratio Setting
Choose stored formula on PLC touch screen; set A:B ratio (100:100‑130) and temperature parameters (20‑45℃) for the specific panel type.
High‑Pressure Pouring & Curing
PU rigid foam is injected between facing layers at 10‑18 MPa; panel travels through heated rollers/molds for controlled curing and expansion.
Cutting, Stacking & Cleaning
Continuous panel is cut to specified lengths, stacked for packing; automatic circulation + air purge cleaning prepares mixing head for ongoing production.

Stepless speed regulation (1‑15 m/min) ensures maximum throughput and flexibility; integrated conveying, pouring, curing, cutting, and stacking in one continuous process.
High‑Pressure Precise Mixing & Foaming
Metering and mixing are configured for the selected recipe. Cell structure, thermal insulation and compression resistance require panel tests.
Accurate Two‑Component Metering & Ratio
Dynamic metering accuracy of ≤±0.3% and ratio control (100:100‑130) maximize raw material utilization, reducing production loss and costs.
Full‑Line Linkage Intelligent Control
PLC + touch screen integrates all production sections; real‑time monitoring and automated adjustments enable rapid switching between multiple panel specifications and thicknesses.
Multi‑Material Facing Compatibility
Supports various facing materials including color steel, aluminum foil, paper honeycomb, and custom composites, offering versatility for different insulation applications.
Solvent‑Free Eco‑Friendly Cleaning
Automatic circulation + air purge cleaning eliminates chemical solvents, reduces environmental impact, and simplifies maintenance for continuous long‑run production.
