The XINNUO Rockwool Sandwich Panel Production Line is a fully continuous and automated production system, integrating mechanical, electrical control, hydraulic systems, and polyurethane/rockwool composite technology. The line adopts advanced international roll forming technology, digital servo control, frequency vector control, and automatic stacking systems, ensuring high efficiency, stability, and intelligent production.
The production line features a reasonable structure, easy operation, and complete functionality. Panels are manufactured through processes including feeding, profiling, glue application, heating, trimming, grooving, and cutting.
Key highlights:
Produces flat and corrugated sandwich panels of multiple specifications
Sandwich panel thickness: 40–300 mm; Width: 950–1200 mm (flat) / 950–980 mm (corrugated)
Supports EPS or rockwool core material, meeting different fire resistance, thermal insulation, and soundproofing requirements
Compatible with color steel, aluminum, or stainless steel sheets
Steel Plate Decoiling Machine
Hydraulic mandrel for automatic operation and stable sheet feeding
Roll Forming Machine
Continuously forms steel sheets into flat or corrugated profiles
Quick mold change via cassette and rail wheel system
Preheating Room
Hot air circulation preheats the sheet to optimal temperature for EPS or rockwool composite
Glue Coating Device
Evenly applies adhesive for strong bonding between steel sheet and core
Options: mixing type (cost-effective) or spray type (reduces adhesive consumption)
Double Belt Laminating System
Applies constant pressure and heat to form the sandwich panel
Ensures flat surface, uniform thickness, and anti-deformation
Band Saw Cutting Machine
Cuts panels to customer-specified lengths
Supports multiple cutting methods
Cooling System
Ensures stable panel formation and high product quality
Stacking System
Automatically stacks finished panels
Cross-stacking available for roof panels if required
Packaging Machine
Wraps panels with plastic film (4-side or 6-side)
Optional pallet system automatically inserts EPS spacers for easier transportation and storage
