Shanghai Zhongji Rock Wool Sandwich Panel Line – A-Class Fireproof Panel Production Equipment for Safe Public & Industrial Buildings

With global building fire safety codes and construction standards becoming increasingly rigorous for public and industrial projects, Shanghai Zhongji has independently developed a heavy-duty, highly stable rock wool sandwich panel line. Tailored for continuous and large-scale production of standard A1 and A2 grade fire-resistant rock wool composite panels, this automated equipment fully complies with international fire certification requirements across different countries and regions. Adopting mature industrial manufacturing technology and optimized structural design, the production line supports long-term stable continuous operation, enabling building material manufacturers to mass-produce high-standard fireproof panels that meet global building safety and engineering acceptance regulations.

Rock wool sandwich panels are premium fireproof building materials recognized worldwide, featuring excellent fire resistance, sound insulation, thermal insulation and high-temperature resistance. The non-combustible rock wool core can effectively block flame propagation and resist high-temperature erosion, greatly improving the overall fire safety performance of buildings. As essential enclosure materials for high-risk construction scenarios, they are widely applied in industrial workshops, large warehouses, hospitals, schools, office buildings, clean rooms and public infrastructure projects, gaining extensive approval in standardized global construction projects.

Targeting the unique physical properties of rock wool, including high density, heavy weight and easy fiber shedding, our rock wool sandwich panel line has undergone targeted structural optimization and technological upgrading. Equipped with an intelligent automatic rock wool stacking and distributing system, the equipment realizes automatic sorting, orderly arrangement and seamless splicing of rock wool strips during continuous operation. It thoroughly eliminates common defects such as internal hollow gaps, uneven arrangement and empty layers, ensuring outstanding compactness and consistent structural integrity of finished rock wool composite panels.

To deliver high-strength, long-lasting composite bonding, the production line adopts advanced uniform atomized continuous spray gluing technology. The precision gluing system evenly applies eco-friendly high-quality adhesive on the bonding surfaces of rock wool cores, color steel sheets and aluminum sheets, forming uniform, firm and high-adhesion composite layers. This professional gluing process avoids insufficient glue volume, uneven coating and local degumming, effectively preventing panel delamination, cracking and bulging during long-term service and greatly extending the service life of finished rock wool sandwich panels.

The entire rock wool sandwich panel production line adopts a thickened heavy-duty steel frame and high-precision imported electrical components, featuring a sturdy structure, strong vibration and compression resistance, and excellent durability. Integrated with an intelligent tension control system and dual-belt constant-pressure composite technology, the equipment maintains stable pressure and uniform speed under long-term high-load operation. It stably produces high-density thick rock wool panels with thicknesses from 50mm to 250mm at a steady speed of 3 to 6 meters per minute, fully satisfying the high-volume and high-precision production needs of large-scale fireproof panel manufacturers.

This fully automated rock wool sandwich panel line integrates complete intelligent production procedures, including automatic feeding, precision fixed-size cutting, continuous high-pressure composite forming, edge trimming, accurate sizing and automatic stacking. The unmanned continuous assembly line operation minimizes manual intervention and operational errors, ensuring consistent thickness, stable performance and uniform appearance for every batch of finished panels. All produced rock wool sandwich panels strictly conform to international building fire protection standards and local construction safety specifications.
