Shanghai Zhongji Sandwich Panel Production Line - Automated one-stop production solution for multi category composite panels

As a professional manufacturer specializing in high-end building material forming equipment, Shanghai Zhongji has been driving technological innovation and iterative upgrading of automated sandwich panel production lines for decades. Centering on global market demands and international construction standards, we deliver fully automatic, high-stability and multi-functional standardized turnkey solutions for worldwide composite panel manufacturers. Our universal sandwich panel line adopts mature industrial technologies and optimized structural design, effectively solving industry pain points such as single production type, low automation and unstable quality, and supporting standardized and large-scale factory production.

Composite sandwich panels are premium multi-functional building materials with outstanding thermal insulation, fire resistance, sound insulation and lightweight structural performance. Widely applied in modern industrial workshops, cold storage projects, purification workshops, logistics warehouses and modular prefabricated buildings, these panels meet diverse construction demands. To satisfy customized production requirements of global clients, our independently developed universal continuous sandwich panel line can flexibly manufacture PU, EPS and rock wool core sandwich panels with just one single device.

This high-end universal sandwich panel production line features an integrated fully automatic continuous composite production process without intermittent shutdowns. The complete production workflow covers automatic steel coil uncoiling and leveling, high-precision roll forming, intelligent precise gluing, automatic core material positioning and feeding, dual-belt constant-pressure composite molding, constant-temperature curing, edge trimming, fixed-size cutting and automatic finished product stacking. The whole process maintains high coherence and standardization, minimizing manual intervention and ensuring stable and efficient production of various composite sandwich panels.

The full sandwich panel line supports unmanned continuous assembly line operation, which effectively reduces manual errors and labor costs while greatly improving production efficiency and finished product consistency. Equipped with an industrial-grade PLC intelligent control system and intuitive touch screen interface, the equipment realizes one-click parameter setting, real-time data monitoring and automatic fault alarm. It simplifies daily operation and equipment maintenance, lowers enterprise operational thresholds and achieves intelligent and streamlined factory management.

This universal sandwich panel production equipment operates stably with an adjustable production speed of 3 to 8 meters per minute and a standard effective width of 1250mm. The thickness of finished composite sandwich panels can be customized from 20mm to 200mm to fit various project requirements. All produced panels feature smooth surfaces, uniform internal density and firm bonding without degumming, deformation or hollow defects, fully complying with international building material standards and export inspection specifications.

Featuring strong universality and flexible production performance, this multi-functional sandwich panel line can quickly switch production of thermal insulation, fireproof and lightweight enclosure sandwich panels according to market changes. It helps building material enterprises enrich product portfolios, diversify market layouts, avoid single-product operational risks, and continuously expand global market coverage and comprehensive competitiveness.

With over 30 years of technical accumulation and global market verification, our reliable sandwich panel production lines have been exported to the Middle East, Southeast Asia, Central Asian Russian-speaking regions, Africa, Europe, South America and other global markets. We provide full one-stop services including customized design, factory layout planning, installation and commissioning, technical training and lifelong after-sales support, helping global clients build efficient, profitable and standardized production factories.
