Product Overview
The HF‑CLPS‑Batch is a batch‑type PU sandwich panel line for custom/special‑shaped panels, offering hydraulic clamping, 20‑300 mm thickness, and precise single‑mold control.
This batch‑type polyurethane sandwich panel production line is specially designed for customized PU sandwich panels, special‑shaped panels, and small‑batch panels with non‑standard specifications. It is ideal for laboratory sampling, non‑standard building material production, and specialized insulation panel manufacturing, meeting the core requirements of flexible mold replacement, panel customization, and dense, void‑free cell structure. The system features a hydraulic mold clamping system with precise temperature control, independent two‑component temperature management (20‑45℃) in 100L/200L tanks, and a PLC‑based control system with touch screen interface. The single‑mold foaming control ensures precise forming quality across a wide panel thickness range of 20‑300 mm. The mixing head operates at 8‑15 MPa with dynamic metering accuracy of ≤±0.3%, ensuring consistent foam density and ratio stability (polyether:isocyanate = 100:100‑130). The automatic air purge cleaning system is solvent‑free and environmentally friendly, simplifying operation and reducing maintenance costs. With a compact footprint and low investment cost, this line is particularly suitable for small‑to‑medium capacity and multi‑variety flexible production scenarios.
Production Workflow
Mold Preparation & Setup
Install selected mold for desired panel size/shape; set hydraulic clamping pressure and mold temperature (20‑45℃) per insulation requirements.
Recipe Selection & Ratio Setting
Choose stored formula on PLC touch screen; set A:B ratio (100:100‑130) and cycle time (3‑10 min) per panel thickness and density target.
Foam Injection & Molding
Inject PU rigid foam into closed mold at 8‑15 MPa; foam fills cavity and cures under controlled temperature and pressure.
Demolding & Cleaning
Open hydraulic clamp after curing cycle; remove finished panel; trigger automatic air purge cleaning to prepare mixing head for next mold.
