The Haifeng HF-PIR-30M is an automated continuous lamination line designed for high-performance polyisocyanurate (PIR) insulated panels. Combining high-pressure oscillating injection, heated 30-meter caterpillar double belts, and automated packaging systems, it satisfies global demands for cold storage envelopes and architectural facades.
Explore the application solution: Industrial Building Sandwich Panel Production Solution. This solution describes a separate 24 m reference line operating at 3–9 m/min.
Related project: Industrial Plant PIR Sandwich Panel Line. The project records sustained 12 m/min operation on 50 mm wall panels with a 30 m double belt; this is separate from the product's listed 15 m/min maximum line speed.
Production Workflow
Coil Uncoiling & Cold Roll Forming
Steel sheets are cold-rolled into architectural wall or roof profiles
Preheating
Sheet surfaces pass through hot-air tunnels to reach 45°C
High-Pressure PIR Dispensing
Servo oscillating head deposits pentane-blown PIR chemicals evenly
Double-Belt Continuous Curing
30-meter caterpillar maintains uniform hydraulic pressure at 65°C
Synchronous Flying Cut
Disc saw tracks panel movement and cuts to length without stopping
Inline Cooling & Stacking
Turnover rack vents core heat before automated shrink wrapping
Technical Specifications
Supplied HF-PIR-30M configuration references. Speed, thickness and dosing limits are not simultaneous guaranteed working points; actual production depends on cure and material duty.

Key Features
PIR Recipe Control
Main components and additives are selected for the formulation; chemical index is not a certification.
30 m Continuous Belt
The listed 15 m/min upper limit is separate from thickness-specific stable production.
Pentane Handling
Configure detection, ventilation, isolation and interlocks. Certification requires documents for the actual ordered equipment.
