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.
The HF-CLPS-Batch is a batch-type PU sandwich panel line for customized, special-shaped, and small-batch panels with non-standard specifications. It suits laboratory sampling, non-standard building materials, and specialized insulation panels, meeting requirements for flexible mold change, panel customization, and dense, controlled 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 PLC + touch screen control. Single-mold foaming control ensures precise forming across a wide panel thickness range of 20–300 mm. The mixing head operates at 8–15 MPa with ≤±0.3% metering accuracy, ensuring consistent foam density and ratio stability (100:100–130). The automatic air purge cleaning is solvent-free and eco-friendly. With a compact footprint and low investment, this line suits small-to-medium capacity and multi-variety flexible production.
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.
