The development of China's rock wool sandwich panel assembly line manufacturing industry is closely linked to the country's urbanization process and industrial upgrading. In recent years, with the deepening of national strategies such as new urbanization and infrastructure upgrading, the demand for high-quality building materials in fields such as industrial workshops, cold chain logistics, large public buildings and prefabricated buildings has continued to rise. Rock wool sandwich panels, as the preferred material for building envelope systems, have driven the rapid development of the upstream assembly line manufacturing industry. Domestic manufacturers have seized this opportunity to carry out technological innovation and equipment upgrading, transforming from simple equipment imitation to independent research and development, and forming a complete industrial chain covering raw material processing, equipment manufacturing, after-sales service and other links. This industrial chain advantage has not only reduced the production cost of assembly lines but also ensured the stability and reliability of equipment quality, laying a solid foundation for the sustainable development of the industry.

A typical rock wool sandwich panel assembly line in China is a highly integrated continuous automatic production system, which realizes the whole process from raw material input to finished product packaging through precise coordination of multiple links. The production process usually starts with raw material preparation, where metal sheets (such as color steel sheets, stainless steel sheets or aluminum sheets) are uncoiled and cut to the required size by professional decoiling and cutting equipment. At the same time, rock wool core materials, made from natural stone melted at high temperatures, are processed into mats of specified thickness and density through lifting, slitting and turning devices. These core materials, with a melting point of more than 1000°C, are non-combustible and can provide excellent fire protection performance for the final panels. The entire raw material preparation process is controlled by an intelligent system to ensure the stability of material specifications, which is the premise of producing high-quality rock wool sandwich panels.

After the raw material preparation is completed, the assembly line enters the core forming stage. The metal sheets are preheated to the appropriate temperature by a hot air circulation heating furnace to enhance the bonding effect with the core material. Then, the rock wool mats are accurately transported between the upper and lower metal sheets, and special adhesives are evenly sprayed on both sides of the rock wool through an automatic spraying system. The adhesive not only bonds the rock wool fibers tightly but also forms a strong connection between the rock wool core and the metal sheets, ensuring the structural integrity of the sandwich panel. Subsequently, the assembled panel blank enters the rolling and pressing stage, where it is subjected to continuous pressure by a series of rollers and presses to eliminate internal gaps and ensure the flatness and density of the panel. The pressure and speed of this stage are precisely controlled by a frequency conversion vector control system, which can be adjusted according to the thickness and material of the panel to meet different production requirements.

The curing and cooling stage is another key link affecting the performance of rock wool sandwich panels. After pressing, the panel blanks enter the heating curing zone, where they are maintained at a constant temperature for a certain period to ensure the full curing of the adhesive. Domestic manufacturers have optimized the curing process by adopting advanced temperature control technology, which not only shortens the curing time but also improves the bonding strength and durability of the panels. After curing, the panels are cooled by an air cooling system to room temperature, which prevents deformation caused by thermal expansion and contraction and ensures the dimensional stability of the finished products. Finally, the cooled panels are cut to the required length by a band saw cutting system that can work without stopping the machine, greatly improving production efficiency. The cut finished products are then automatically stacked and packaged by a stacking system, completing the entire production process.

Chinese manufacturers of rock wool sandwich panel assembly lines have continuously improved the technical level of equipment, focusing on improving automation, intelligence and energy efficiency. Modern assembly lines are usually equipped with a full computer integrated control system, which adopts digital servo technology and man-machine dialogue interface. Operators only need to input the required parameters (such as panel thickness, width, length and production speed), and the system can automatically complete the entire production process, reducing manual intervention and improving production accuracy. The production speed of these assembly lines can be adjusted between 3 and 8 meters per minute according to product requirements, with an annual output capacity of up to 800,000 to 1 million square meters, which can meet the large-scale production needs of enterprises. In terms of energy saving and environmental protection, manufacturers have introduced waste heat recovery systems in the production line, which can recover and reuse the waste heat generated during the heating process, reducing energy consumption by about 18% to 22% compared with traditional equipment. At the same time, water-based coatings are widely used to replace traditional solvent-based coatings, significantly reducing VOC emissions and meeting the increasingly strict environmental protection requirements.

The flexibility and adaptability of China's rock wool sandwich panel assembly lines are also prominent advantages, which can meet the personalized needs of different customers and application scenarios. These assembly lines can produce panels of various specifications, with panel widths ranging from 600mm to 1200mm, thicknesses from 30mm to 250mm, and lengths from 2000mm to 18000mm. For special application scenarios such as cold storage and high-temperature workshops, manufacturers can customize the assembly line to produce panels with enhanced thermal insulation or high-temperature resistance. In addition, the assembly lines can be compatible with different types of metal sheets and rock wool core materials, allowing customers to choose appropriate raw materials according to their specific needs and budget. This flexibility not only expands the application scope of the assembly lines but also improves the competitiveness of domestic manufacturers in the market.

The application of rock wool sandwich panel assembly lines in China covers a wide range of fields, providing strong support for the development of various industries. In the industrial field, these assembly lines produce rock wool sandwich panels used in the construction of industrial workshops and warehouses, which can effectively improve the thermal insulation and fire safety of the buildings, reduce energy consumption for heating and cooling, and create a comfortable working environment. In the cold chain logistics industry, the panels produced by the assembly lines have excellent thermal insulation performance, which can maintain a stable low temperature inside the cold storage, ensuring the quality of frozen and refrigerated goods and reducing energy loss. In the field of public construction, such as airports, exhibition centers, hospitals and stadiums, rock wool sandwich panels are used for walls, ceilings and partitions, taking advantage of their sound insulation and fire resistance to improve the safety and comfort of the buildings. In addition, with the development of prefabricated buildings, rock wool sandwich panel assembly lines have become an important equipment support for prefabricated component factories, realizing the standardized and large-scale production of prefabricated components and shortening the construction period by more than 40%.
