Composite board production line

The composite panel production line is a complete set of equipment that combines metal panels with insulation/filling core materials through continuous automation processes, used for mass production of building enclosure panels with functions such as strength, insulation, and sound insulation.

Core Definition and Classification

Core definition: A production line that uses metal sheets (color coated sheets, galvanized sheets, etc.) as panels, combined with core materials such as polyurethane (PU), rock wool (RW), polystyrene (EPS/XPS), etc., and integrates molding, bonding, and cutting to produce composite sandwich panels.

Main classification: polyurethane composite board production line, rock wool composite board production line, foam (EPS/XPS) composite board production line according to core materials; According to the function, it can be divided into single core material production line, multi core material dual-use/all-in-one machine (such as rock wool foam dual-use line).

core functionality

Panel processing: Complete the unwinding, leveling, and cold bending of metal coils (flat or corrugated) to ensure the flatness and forming accuracy of the panel.

Core material composite: By coating, foaming, rolling/hot pressing and other methods, the panel is tightly adhered to the core material to avoid delamination and hollowing.

Fixed length cutting: Accurately cut composite panels according to preset dimensions, with smooth and burr free cuts, suitable for different construction needs.

Auxiliary processing: Some models support additional processes such as curling, slotting, and laminating to improve the installation convenience and surface protection of finished boards.

Core structure (universal configuration)

Feeding unit: including panel unwinding rack and core material conveying rack, equipped with tension control and correction device to ensure smooth feeding without deviation.

Forming unit: Panel cold bending forming machine, which processes metal coils into preset shapes through multiple component rollers, adapting to different panel styles.

Composite unit: coating device (roller coating/dripping/spraying), composite host (rolling/hot pressing mechanism), core ensures the bonding strength between the panel and the core material.

Cutting and receiving unit: flying saw or hydraulic cutting device, finished product receiving rack, some with waste recycling device to improve material utilization.

Electronic control unit: PLC intelligent control system+touch screen, supporting parameter setting (board thickness, length, speed), specification storage, and one click changeover.

Core Features

High degree of automation: Continuous operation from feeding to finished product output, requiring only 1-3 people to operate, significantly reducing labor costs.

Wide adaptability: panel thickness of 0.3-1.0mm, core material thickness of 50-250mm, and board width of 1000-1200mm can be flexibly adjusted, supporting multiple panel styles and core material combinations.

High molding accuracy: The thickness error of the composite board is ≤± 0.5mm, with regular dimensions, smooth surface, and firm adhesion without delamination.

Balancing efficiency and performance: With a production speed of 5-20m/min, a single shift can produce thousands of square meters of sheet metal; The finished product has multiple properties such as lightweight, high strength, insulation, and fire resistance (rock wool core material).

Applicable scenarios

Industrial buildings: For the walls and roofs of factories, warehouses, and workshops, rock wool (fireproof) and polyurethane (high-efficiency insulation) composite panels are preferred.

Civil buildings: exterior wall insulation board and interior wall partition board of villas, apartments and rural self built houses, suitable for foam (cost-effective) and polyurethane (comfortable thermal insulation) core materials.

Special buildings: cold storage, clean workshops, data centers, using composite panels with polyurethane or XPS core materials to meet high insulation, moisture-proof, and clean requirements.

Temporary buildings: prefabricated houses, temporary buildings on the construction site and kiosks are made of foam composite boards, giving consideration to construction convenience and cost advantages.
