Composite board production line

Composite panel production line is an automated and continuous large-scale equipment used for producing metal faced composite panels (commonly known as "sandwich panels"). The composite board produced by it consists of two layers of metal panels (such as color steel plate, aluminum plate, stainless steel plate) and a core material (such as rock wool, polyurethane, polystyrene, etc.) filled in the middle, which are formed in one composite molding in the production line. It has excellent properties such as insulation, heat insulation, fire resistance, and sound insulation.

Composite board is a type of "sandwich" structural board:

Upper panel: decorative and protective layer.

Core layer: Functional layer (insulation, fire prevention, sound insulation).

Lower panel: Decorative and protective layer.

The composite board production line is an automated complete set of equipment that combines panels (metal plates) and core materials (insulation/filling materials) into one through continuous forming, bonding, cutting, and other processes. The core is used to produce composite boards with insulation, sound insulation, and load-bearing properties.

core functionality

Metal panels (color coated panels, galvanized panels, etc.) are combined with core materials (polyurethane, rock wool, polystyrene, etc.) through continuous processes such as panel forming, core material laying, composite bonding, and fixed length cutting to produce sandwich composite panels in one go. The finished product can be directly used for building enclosure structures.

Core structure

Panel forming unit: including upper/lower panel unwinding, leveling, and cold bending forming devices, which process metal coils into preset corrugated or flat shapes.

Core material processing unit: configured according to the type of core material (such as polyurethane foaming machine, rock wool/polystyrene board conveyor rack), to achieve automatic laying of core material or on-site foaming filling.

Composite bonding unit: The panel is tightly adhered to the core material through hot pressing, rolling, or bonding techniques. Some models are equipped with adhesive devices (suitable for bonding core materials).

Cutting and receiving unit: flying saw or hydraulic cutting device for fixed length cutting, with a smooth cut; The receiving rack receives finished boards, some of which are equipped with film covering devices to protect the surface.

Electrical control system: PLC intelligent control, supporting parameter settings for sheet thickness, length, and forming speed, touch screen operation, and can store multiple specification parameters.

Features of the equipment

High composite precision: The panel is tightly adhered to the core material without delamination or hollowing, with a thickness error of ≤± 0.5mm and regular dimensions.

Wide adaptability: capable of processing metal panels with a thickness of 0.3-1.0mm, supporting various core materials such as polyurethane (PU), rock wool (RW), polystyrene (EPS), etc. The board width is usually 1000-1200mm, and the thickness can be adjusted from 50-200mm.

High production efficiency: molding speed 5-20m/min, continuous automated operation, single shift can produce thousands of square meters of composite boards, suitable for engineering batch supply.

Multi functional: Some models support "one machine for multiple uses" and can switch to produce sandwich wall panels, roof panels, cold storage panels, etc. Some models have modified functions for fire and moisture prevention.

Applicable scenarios

Industrial buildings: walls and roofs of factories and warehouses, producing rock wool composite panels (fireproof) and polyurethane composite panels (insulation), balancing protection and energy conservation.

Civil buildings: External wall insulation boards and internal wall partition boards for villas and apartments, compatible with polystyrene/polyurethane core materials to enhance living comfort.

Special buildings: cold storage, clean workshops, data centers, producing composite panels with high insulation, moisture resistance, and sound insulation to meet special environmental requirements.

Public buildings: The enclosure structures of shopping malls, hospitals, and schools are made of fire-resistant rock wool composite panels, which meet fire safety requirements.

Common types (classified by core material)

Polyurethane (PU) composite board production line: on-site foaming of core materials, good insulation effect, suitable for high-end insulation scenarios.

Rock wool (RW) composite board production line: The core material is rock wool, which is fire-resistant and commonly used in industrial and public buildings.

Polystyrene (EPS/XPS) composite board production line: The core material is polystyrene board, which has a low cost and is suitable for ordinary insulation needs.
