QS800 Bidirectional Static Pressing Brick Machine
Upper and lower pressing together for even brick density, no pallet handling, low noise.
The QS800 is a hydraulic brick-making machine that forms bricks by bidirectional static pressing. Upper and lower rams close on the mold at the same time, so pressure arrives from both directions and the mix compacts evenly through the full height of the brick. The result is consistent density and uniform strength with no layering, bulging, or cracking, and flexural and compressive values that beat unidirectional equipment. That makes it a strong choice for large scale runs of high strength standard bricks, hollow bricks, and solid bricks. Three traits define it in a plant: labor saving, pallet free operation, and a fully automatic sequence. Bidirectional static pressing produces no high frequency vibration, so noise stays low and the workshop environment improves. A PLC based control system links material distribution, bidirectional pressing, demolding, and brick discharge, and because no pallets are handled by hand, human input drops and labor cost follows. The frame is a heavy duty integrated steel structure that has been stress relief aged, giving rigidity and load capacity that hold under continuous high pressure. Mold changes cover standard bricks, hollow blocks, and solid bricks, and the press accepts fly ash, slag, and construction debris.

Upper and lower rams press together so density stays even through the full brick height., Bricks show no layering, bulging, or cracking, with strength above unidirectional presses., The 18 to 22 second cycle runs without pallets, so nobody carries boards in or out., PLC automatic control links distribution, pressing, demolding, and discharge in one sequence., Stress relief aged steel frame keeps rigidity under prolonged high pressure operation.
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.
Two Rams, One Even Brick
The QS800 forms bricks by bidirectional static pressing. A hydraulic ram works from above while a second works from below, and both close on the mold together. Pressure therefore arrives from two directions at once and the mix compacts evenly through the full height of the brick, rather than packing harder at the face nearest the ram.
Density and Strength Without Defects
Because compaction is symmetrical, the finished brick shows consistent density and uniform strength from top to bottom. Layering, bulging, and cracking are avoided, and flexural and compressive values sit above what traditional unidirectional pressing achieves. That places the model at the front of large scale production of high strength standard bricks, hollow bricks, and solid bricks.
Labor Saving, Pallet Free, Automatic
Three advantages define daily operation. The cycle saves labor because it runs on its own. It works without pallets, so no one carries boards in and out of the press. And a PLC based automatic control system joins material distribution, bidirectional pressing, demolding, and brick discharge into one linked sequence, removing manual pallet handling and cutting labor cost. Operators need little retraining, since the panel works the same way as other static presses in the range.
Noise and Workshop Conditions
Bidirectional static pressing generates no high frequency vibration. Noise levels stay low compared with vibration machines, the floor sees less shock, and the production hall becomes a more comfortable place to work. For plants near housing, that difference often decides the equipment choice.
Frame and Long Run Costs
The machine uses a heavy duty integrated steel structure that has undergone stress relief aging treatment. It holds strong rigidity and high load capacity, and stays free of deformation even under prolonged high pressure operation. Failure rate stays low, maintenance is straightforward, and long term operational costs remain predictable. A level foundation and straight alignment keep that advantage over the years, and spare parts stay easy to source.
Molds, Materials, and Figures
Changing molds lets the QS800 produce standard bricks, hollow blocks, and solid bricks, covering municipal engineering, civil construction, and rural infrastructure. Raw material compatibility is broad, with fly ash, slag, and construction waste all usable, which trims cost while recycling industrial solid waste. Key figures are a maximum pressure of 31.5 MPa, a 500 mm main hydraulic cylinder bore, a molding cycle of 18 to 22 seconds, a molding area of 1,100 x 680 mm, total power of 70 kW, and machine weight of about 22 to 25 tons.
