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.
This continuous polyurethane sandwich panel production line is specially designed for large‑scale, high‑volume manufacturing of insulation panels used in building exterior walls, cold storage walls, clean workshops, and prefabricated buildings. It supports composite with various facing materials including color steel, aluminum foil, and paper honeycomb, meeting the core requirements of uniform panel density, thermal insulation, flame retardancy, compression resistance, and standard dimensional accuracy. The system features independent temperature‑controlled tanks (200L/300L) with two‑component independent temperature management (20‑45℃), a high‑pressure mixing head (10‑18 MPa) with dynamic metering accuracy of ≤±0.3%, and a PLC‑based full‑line linkage control system with touch screen interface. The production line speed is continuously adjustable from 1 to 15 m/min via stepless speed regulation, enabling rapid switching between different panel thicknesses (30‑200 mm) and specifications. The heating system employs precise roller and mold temperature control to ensure optimal curing conditions. The cleaning system combines automatic circulation and air purge cleaning, completely solvent‑free and environmentally friendly, reducing maintenance time and chemical waste. This line significantly improves production efficiency and capacity 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.
