QST1500 Fully Automatic Concrete Block Molding Machine
Servo-driven block molding machine for stable, dense concrete block output.
The QST1500 is a fully automatic concrete block molding machine built for medium and large building materials plants. Its core drive combines a servo system, high-frequency vibration and hydraulic pressurization, so the machine forms blocks quickly while holding pressure steady. An imported hydraulic system and servo closed-loop control keep the forming cycle consistent, and the vibration unit packs the mix densely for uniform strength and accurate dimensions. The machine is designed for continuous operation, with a low failure rate and controlled maintenance costs. An imported PLC touch-screen panel handles one-touch parameter changes, live monitoring and automatic fault alarms, so operators need little training. A rapid arch-breaking distributor feeds porous and hollow shapes evenly without dead zones, which reduces chipped corners and density swings. Fly ash, slag and coal gangue can make up a large share of the mix. Forming molds pass through high-temperature heat treatment for wear and deformation resistance, holding precise tolerances over a long service life. The QST1500 suits municipal, civil construction and landscape projects, and the QST range also covers the QST1000, QST1200 and QST1800 for different output targets.

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.
The QST1500 is the largest unit in the QST servo brick machine line, aimed at medium and large building materials enterprises that need steady, high-volume output. It is used for municipal engineering, civil construction and landscape work, and it runs as the main forming machine on a full block production line. It suits municipal engineering, civil construction and landscaping, where a steady, accurate supply of blocks matters, and it works as the forming machine inside a full line, taking mixed material from the batching system and passing formed pallets on to the curing and palletizing stages.
Servo Drive, Vibration and Hydraulic Forming
The QST1500 forms blocks through three combined forces: a servo drive, high-frequency vibration and hydraulic pressurization. Servo closed-loop control holds the pressure curve steady from cycle to cycle, so each block leaves the mold with the same density and dimensions. The imported hydraulic system keeps the forming speed high without sacrificing stability. The vibration unit works at 3800 to 4500 cycles, packing the mix so that internal density and strength stay uniform. Because the machine is built for round-the-clock duty, downtime and maintenance costs stay low.
Control, Monitoring and Fault Handling
An imported PLC touch-screen system runs the machine. Operators change molding parameters with one touch, watch equipment status live, and receive automatic alarms when a value drifts out of range. This level of automation cuts the skill needed on the floor and lowers labor cost. Fault messages point to the area that needs attention, so a shift can act without waiting for a specialist.
Material Distribution and Mix Flexibility
A rapid arch-breaking distributor spreads the mix across the mold box evenly, including for porous bricks and hollow blocks. Even distribution without dead zones prevents chipped corners and uneven density. The mixer accepts fly ash, slag and coal gangue as a large part of the raw material, which lowers material cost and supports cleaner production.
Mold Durability and Model Range
Forming molds go through high-temperature heat treatment, giving them wear resistance and resistance to deformation. They keep precise dimensions and a clean face after long production runs, and they can be swapped to meet different block specifications. The QST platform covers four models, QST1000, QST1200, QST1500 and QST1800, so a plant can match output to its market.
