The QST1500 fully automatic concrete block molding machine (servo brick machine) is a high-efficiency, automated block-forming equipment developed by Qisheng Machinery for medium- and large-scale building materials enterprises. Featuring servo drive, high-frequency vibration, and hydraulic pressurization as its core technologies, it achieves high-speed, stable, and high-quality block production, making it the mainstay model for block manufacturing in municipal engineering, civil construction, landscape gardening, and other applications.

Core Advantages and Features
- High-Efficiency and Stable Molding Performance
Equipped with an imported high-efficiency hydraulic system and servo closed-loop control, it delivers fast molding speeds and stable pressure output. Combined with a high-frequency vibration device, it produces blocks with high internal density, uniform strength, and stable dimensional accuracy, capable of continuous 24-hour operation over long periods, with low failure rates and controllable maintenance costs. - Intelligent and Convenient Operating System
Featuring an imported PLC touch-screen control system, it offers a high degree of automation, simple and intuitive operation, and supports one-touch adjustment of molding parameters, real-time equipment monitoring, and automatic fault alarms, significantly lowering the barrier to manual operation and reducing labor costs. - Uniform Material Distribution and High Adaptability
Equipped with a rapid arch-breaking material-distribution device, it demonstrates strong adaptability to complex brick types such as porous bricks and hollow blocks, ensuring even material distribution without dead zones, effectively preventing issues like chipped corners or uneven density. It can also make extensive use of industrial waste materials such as fly ash, slag, and coal gangue, enabling green and environmentally friendly production. - Durable and Reliable Mold Technology
The forming molds undergo high-temperature heat treatment, providing excellent wear resistance and deformation resistance, resulting in a long service life. Even after prolonged production, they continue to maintain precise dimensions and superior surface quality, meeting diverse block-specification requirements.
