QST1000 Servo-Driven Automatic Concrete Block Machine
Closed-loop servo drive holds position, speed and torque steady on every forming cycle
The QST1000 is a block forming machine for medium and large building materials producers. It combines electrical and hydraulic control with a servo motor drive, which gives closed-loop control of position, speed and torque instead of the open-loop behaviour of a stepper motor. That keeps forming accuracy the same on the first block of a shift and on the last, and it removes the step loss that appears on stepper driven machines. The vibration feeding system accepts a wide product range: curb stones, slope protection bricks and interlocking blocks as well as ordinary structural units. The machine is used for municipal engineering, civil construction and landscape gardening work, and it is aimed at producers moving toward larger, more automated output. Plant figures from the series show full PLC control of the process lowering labour cost by 15 percent, electro-hydraulic integration raising production efficiency by 20 percent, suspension-type vibration cutting noise by 10 percent, real-time fault alarms shortening troubleshooting time by 30 percent, and an intelligent start program adding 20 percent to working efficiency.

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.
Servo Drive Instead of a Stepper Motor
On many block machines the mold and feed movements are driven by stepper motors, which run open loop: the controller sends a number of steps and assumes the axis has arrived. When load rises or the machine heats up, steps are lost and the position drifts. The QST1000 uses a servo motor drive instead. Position, speed and torque are measured and corrected in a closed loop, so each movement finishes where it was told to finish. The practical result is uniform forming accuracy from the start of a shift to the end, no step loss, quieter running and less heat, with faster response than a stepper arrangement offers.
Electrical and Hydraulic Control Together
The machine joins electrical and hydraulic control in one system rather than treating them as separate areas. Compared with conventional block machines this arrangement gives higher production efficiency, lower energy consumption per block and better economic return on the capital spent. The vibration feeding section is designed to handle a broad product set, so switching from a curb stone order to interlocking blocks does not demand a different machine.
Where the Series Performs
The QST1000 is the mainstay model for block production in municipal engineering, civil construction and landscape gardening, and it is also chosen by producers moving toward large scale, automated manufacturing. It suits plants with a settled product range and steady demand, where machine availability over a year matters more than peak output on a single good day. The servo system reduces wear and stops the small position errors that slowly spoil face quality on decorative products such as paving and interlocking units.
Control and Fault Handling
Full-process PLC control runs the machine and lowers labour cost by 15 percent while cutting dependence on manual intervention. Material mix ratios are stored in the PLC controller, so proportions are repeated exactly instead of being set by hand at each changeover. Real-time fault alarms shorten troubleshooting time by 30 percent, which reduces the hours lost when a fault appears mid shift. An intelligent start control program adds 20 percent to working efficiency by bringing the machine to working condition in an orderly sequence rather than by trial and error.
Noise, Efficiency and Models
Suspension-type vibration lowers noise by about 10 percent compared with a conventional mounting, which improves the working environment around the machine. Electro-hydraulic integration raises production efficiency by 20 percent. The model range covers QST1000, QST1200, QST1500 and QST1800, so a plant can start with the smaller unit and specify a larger frame in the same series when demand grows, keeping the control system, spare parts and operating practice consistent across the line.
