Wall sandwich panel machines typically consist of core components such as unwinding systems, forming units, gluing devices, composite presses, cutting units, and stacking systems. The equipment adopts modular design and can be flexibly configured according to different product requirements to produce sandwich panel products with various thicknesses (50-300mm), widths (600-1200mm), and lengths. The production speed can reach 5-15 meters per minute, and the maximum daily output can be over 5000 square meters.
