Mana Launches a New Ring-Type Gypsum Wall Panel Production Line

The gypsum hollow wall panel is produced using industrial by-product hemihydrate desulfurized gypsum or hemihydrate phosphogypsum as the main binder. It is reinforced with both coated fiberglass mesh and chopped glass fibers, and uses wet-discharged fly ash (bottom ash) as a lightweight filler. With suitable modified additives, the panels are formed by vertical casting in moulds. The finished panels feature excellent flatness, light weight, sound insulation, and resistance to cracking and deformation, making them an ideal choice for lightweight interior partitions in high-rise buildings.

The ring-type gypsum wall panel production line is a newly developed layout by MANA, designed specifically for gypsum materials. The core equipment is arranged in a circular configuration, where sets of vertical moulds travel along a ring-shaped track. This design eliminates the need for shuttle cars, greatly improving production efficiency. The line is highly automated, significantly reducing labor costs.

The demoulding system consists of a demoulding machine and a tilting machine. The demoulding machine uses a single-pull mechanism driven by a variable-frequency motor, offering strong traction, smooth operation, and high efficiency. The extracted panels are automatically closed and clamped through a hydraulic system. The tilting machine, also hydraulically driven, rotates the wall panels 90 degrees and automatically separates them from the aluminum base mould. It then performs a second 90-degree rotation to complete the entire demoulding process.
