QST1800 Foamed Cement Wallboard Production Line
Automated mould circulation line for lightweight foamed cement wall panels.
The QST1800 wallboard line produces lightweight foamed cement panels through an automated mould circulation, from raw material preparation to packed finished board. Aluminium alloy moulds are assembled to the panel specification and locked with male and female groove fixings, so panel edges come out straight and ready to join on site. Reinforcement bar or wire mesh is placed in the mould before pouring for impact and crack resistance. Cement, fly ash and EPS beads are proportioned by a metering system, then mixed and foamed in a twin-shaft mixer into a uniform lightweight slurry. A mobile mould cart carries the mould to the pouring station, the slurry is injected to fill the cavity completely, and the cart then moves it to the curing area. After setting, an automatic plate removal machine strips the panels from the moulds, the panels go to curing, and the empty moulds return to assembly through a circulation system. Finished boards are inspected, packed and dispatched, so the line runs as a closed loop with little manual handling between stages. Mould count and curing area, not pouring speed, set the daily output ceiling, so both are fixed when the line is sized.

Typical decision factors
What changes the machine price?
Daily capacity
Output target determines machine size, mould cycles and line configuration.
Automation
Pallet handling, cubing, batching and packaging change total project scope.
Block types
Hollow block, paver, interlock and curbstone may require different moulds and handling.
Service scope
Shipping, installation, training and spare parts are quoted by destination.
Mould Assembly and Reinforcement Placement
The cycle starts with the mould. Aluminium alloy side forms are assembled to the wall panel specification and locked with male and female groove fixings around the perimeter. Those fixings shape the panel edge as it cures, so the board arrives on site with a straight profile that can be joined without extra dressing.
Before pouring, a reinforcement bar or a wire mesh is placed inside the mould. Its job is structural rather than cosmetic: the mesh takes the tensile load in a foamed panel, which improves impact resistance and limits cracking during handling and installation.
Metering, Foaming and Pouring
Cement, fly ash and EPS beads are proportioned by a metering system and fed to a twin-shaft mixer, where high speed mixing and foaming produce a uniform lightweight slurry. Metering accuracy decides whether the panel hits its target density, and density in turn decides strength, weight and thermal performance.
The mixed slurry is injected into the mould through the pouring system, filling the cavity completely and leaving no voids or trapped bubbles, since a hole in the panel is a weak point that inspection cannot repair. The mobile mould cart then moves the filled mould to the curing area, where the slurry sets and solidifies in shape.
Demoulding and Mould Circulation
Once the board has set, an automatic plate removal machine lifts the finished panel out of the mould. Panels continue to the curing zone for their remaining curing period, while the empty moulds travel back to the assembly station on a circulation system and are refilled.
That return loop is what sets the production rate of the line. The number of moulds in circulation, not the nominal pouring cycle, decides daily output, which is why mould count is the first figure to agree on when a plant is sized.
Inspection, Packing and Dispatch
After curing, each wallboard is inspected for dimensions, edge quality and surface defects. Boards that pass are packed and prepared for dispatch, with rejected units pulled before they reach transport.
Because the line works as a closed loop, the crew is mainly monitoring stations rather than handling panels, which keeps product quality consistent across shifts and reduces the physical load on the operators. Mould cleaning and release agent application remain the two housekeeping tasks worth scheduling daily.
Mould cleaning and release agent application are the two routines worth scheduling daily, since slurry bonds to an unclean mould face and reappears as chipped edges at final inspection.
