The QST1800 fully automatic concrete block molding machine (servo brick machine) is a high-end flagship block-forming equipment developed by Qisheng Machinery for large-scale building materials enterprises. Featuring servo drive, an imported high-efficiency hydraulic system, and extended high-frequency vibration technology, it achieves high-speed, stable, and high-density molding of concrete blocks, making it the mainstay equipment for block production in large-scale municipal projects, major civil construction, landscape gardening, and other applications.

Core Advantages and Features
- High-Efficiency, Energy-Saving Power System
It adopts imported high-efficiency hydraulic proportional system components, ensuring stable power output, rapid response, and efficient, energy-saving operation. Paired with servo closed-loop control, it delivers fast molding speeds and precise pressure control, enabling long-term continuous 24-hour operation with low equipment failure rates and controllable maintenance costs. - Intelligent and Convenient Automated Control
Equipped with an imported intelligent PLC touch screen and genuine electrical components, it boasts a high degree of automation and simple operation. It supports one-touch adjustment of molding parameters, real-time monitoring of equipment operating status, and automatic fault alarms, significantly lowering the barrier to manual operation and reducing labor costs. - Uniformly Adaptable Material Distribution and Molding Process
It features a quick material distribution device with arch-breaking capability, offering excellent adaptability to complex brick types such as porous bricks and hollow blocks. The material distribution is uniform with no dead zones, effectively preventing issues like chipped corners or uneven density. Its extended high-frequency vibration technology greatly shortens the molding cycle and enhances internal compactness, resulting in higher product strength and superior water resistance and freeze-thaw performance. - Durable and Reliable Mold Technology
The forming molds undergo a special high-temperature heat treatment process, significantly improving wear resistance and deformation resistance, thereby extending their service life. Even after prolonged production, they can still maintain the precision of product shaping and the quality of appearance, meeting diverse specifications for block production.
