Haifeng successfully engineered and commissioned a large-format rigid polyurethane decorative panel molding line for a major architectural millwork manufacturer in China, achieving monolithic one-piece molding of 1200mm × 2400mm 3D deep-relief carved wall panels with finished-panel emissions requiring formulation-specific testing. The project delivered a customized high-output high-pressure PU dosing system, wide-platen hydraulic mold clamping presses, and synchronized thermal fluid management skids.

Prior to commissioning, the manufacturer produced 3D wall panels using multi-axis CNC routing on MDF and plywood boards. CNC machining was cost-prohibitive, generated airborne wood dust hazards, and destroyed wood-grain texture, while adhesive binders emitted formaldehyde that failed green building certifications. The client required an advanced chemical molding solution capable of casting large 1.2m × 2.4m panels in a single shot, flowing into delicate 40mm relief undercuts, and delivering lightweight structural panels compatible with standard carpentry mounting cleats.

Operating since September 2025 on a two-shift daily schedule across a 420 m² workshop, the workcell outputs over 400 large-format carved panels daily. By implementing Haifeng's closed-loop Ratio Lock flow algorithms and high-velocity impingement injection, the brief describes decorative wall-panel production; finished-panel emissions and fire classification require the applicable specimen tests and reports.

Project Technical Specification Matrix:

Haifeng deployed a high-capacity rigid polyurethane reaction workcell engineered for oversized architectural wall panel tooling:

1. High-Output Stoichiometric Dosing: Heavy-duty axial displacement pumps meter low-viscosity rigid precursors at up to 80 kg/min with ±0.5% precision, distributing chemicals across wide panels before gelation.
2. Wide-Platen Hydraulic Clamping: A 2.6m × 1.4m hydraulic press provides synchronized clamping force, ensuring dead-flat panel perimeter edges and uniform 15mm–45mm relief depths.
3. Multi-Zone Mold Oil Heating: Dynamic TCU circuits maintain platen temperatures at 52°C across expansive dimensions, preventing flow hesitation and telegraphing grain defects.
4. Self-Cleaning High-Pressure Injection Head: An industrial impingement head executes instantaneous 0.3s shut-offs without chemical solvents, preserving mother-tool fidelity.

Installation and commissioning: 20 days. Operator training: 4 days. Warranty: 1 year. Long-term spare parts and remote PLC diagnostic support are available.
