2. Core Material Feeding and Composite System: Equipped with an automatic core material feeding system, it is compatible with various core materials such as polyurethane, rock wool, and glass wool. It enables uniform feeding and precise compounding of core materials and color steel panels. Adopting double-track pressing technology, it ensures firm bonding between the core material and the panel, with the uniformity error of core material density controlled within ≤3%.

3. Cutting and Stacking System: Equipped with a high-precision automatic cutting device, it can cut the composite sandwich panels according to preset sizes with a length error of ≤0.5mm. The automatic stacking system can sort and stack finished products in an orderly manner, reducing manual operations and improving production efficiency.

4. Gluing System: As a key link connecting the core material and the panel, it is equipped with a fully automatic precision gluing device adopting airless spraying technology. The glue coating is uniform with controllable thickness (0.1-0.3mm), and the glue layer has strong adhesion. This effectively prevents degumming and bulging of the sandwich panel, extends the product service life, is compatible with composite glues of different viscosities, and cooperates seamlessly with the core material feeding and composite system.

5. Forming and Rolling System: On the basis of uncoiling and leveling, it adopts multiple sets of precision forming rolls with hardened surfaces, which are wear-resistant and durable. It can realize various corrugated forming of color steel panels (such as corrugated, flat, and embossed) with high forming precision, no scratches or deformation on the surface. It not only maintains high-precision performance but also meets the appearance and usage needs of different customers.

6. Electrical Control System: As the "central nervous system" of the equipment, it adopts an imported PLC control system combined with a high-definition touch screen. It can real-time monitor the operation status of each process, including uncoiling, gluing, forming, and cutting, realize one-click parameter retrieval and real-time fault alarm, support remote debugging and maintenance, reduce the difficulty of equipment operation and maintenance, and ensure continuous production.

Main Characteristics:

1. High-Precision Forming Performance: The equipment adopts a servo motor drive system and closed-loop control technology, ensuring that the wave peak height error of the metal panel is ≤0.1mm and the thickness error of the finished sandwich panel is ≤0.2mm. The product qualification rate is as high as over 99%, fully meeting the quality requirements of industrial construction, cold chain logistics and other fields.

2. Strong Versatility and Flexibility: Adopting a modular design, the equipment can quickly switch the production specifications of sandwich panels with a thickness of 50-1500mm by replacing rolling molds and gluing systems. It is also compatible with multiple core materials such as polyurethane, rock wool, and glass wool, meeting the diverse production needs of different customers.

3. Energy-Saving and Efficient Production: Equipped with an energy-saving motor and waste heat recovery device, the equipment reduces energy consumption by 20-25% compared with traditional equipment. The daily output of a single line can reach 3000 square meters, greatly improving production efficiency and reducing production costs for manufacturers.

4. Strong Forming Stability: Adopting a rigid body design, it reduces vibration during equipment operation. With synchronous transmission technology, it ensures the coordinated operation of each process, including uncoiling, leveling, gluing, compounding, and cutting, avoiding panel offset and core material dislocation, and improving the consistency of product forming.

5. Compatible with Various Panel Materials: It is compatible with various metal panels such as color-coated steel plates, galvanized steel plates, and aluminum plates, with a wide thickness range (0.3-1.2mm). It can customize the production of sandwich panels of different materials according to customer needs, expanding the application scenarios of the equipment.

6. Environmentally Friendly and Pollution-Free: There are no waste gas, waste water, or waste residue emissions during the production process. The gluing system uses environmentally friendly glue that meets national environmental protection standards, adapts to the global green production concept, and enhances the core competitiveness of the equipment.

Main Advantages

1. Stable Quality and Reliable Performance: The entire machine adopts high-quality electronic components and pneumatic components, with a failure rate of less than 0.5%. It is equipped with an intelligent fault self-diagnosis function that can early warn potential faults, reduce downtime by more than 30%, and ensure continuous production.

2. Wide Application Range: The color steel sandwich panels produced by the equipment can be widely used in industrial plants, cold storage warehouses, medical clean workshops, public buildings, municipal temporary buildings and other fields. They feature light weight, high strength, fire resistance, and thermal insulation, and are highly recognized by customers in various industries.
