QT4-15 Fully Automatic Concrete Block Molding Machine

The QT4-15 fully automatic concrete block molding machine is a cost-effective, automated, non-fired brick production equipment developed by Qisheng Machinery for small and medium-sized building material enterprises. Integrating mechanical, hydraulic, and electrical control systems, it boasts stable and reliable performance, high productivity, and flexible product adaptability, making it the preferred model for standard brick factories and municipal building material suppliers.

I.Core Process and Automation Configuration

The QT4-15 employs avibration-pressure composite molding process, combining high-frequency vibration with hydraulic pressure to quickly and evenly compact concrete materials within the mold cavity. The molding cycle takes only 15–20 seconds, enabling efficient production of standard bricks, hollow blocks, and other products per mold. The finished products feature high density, minimal dimensional deviations, and stable strength, meeting national building material quality standards.
The entire machine is equipped with a PLC programmable control system and a touch-screen operating interface, allowing one-click completion of parameter settings, operational monitoring, fault alarms, and diagnostics. It supports fully automated operations including material distribution, vibration, pressing, demolding, and brick discharge, seamlessly integrating with batching machines, mixers, conveyors, and automatic palletizers to form a fully automated production line. This significantly reduces reliance on manual labor and lowers labor intensity, achieving standardized, large-scale production.

II. Technical Parameters and Performance Advantages

• The equipment features a high-strength welded frame that is vibration-resistant and durable, capable of long-term operation under high-frequency vibration and high-pressure conditions. Core hydraulic components and vibration motors are sourced from reputable brands, ensuring smooth operation, low failure rates, easy replacement of wear parts, and reduced maintenance costs.
• High Productivity: Each mold can produce 26 standard bricks per cycle, with a single shift (8 hours) yielding 37,440–49,920 bricks. When producing 200×100×60mm paving bricks, each mold yields 15 bricks, resulting in 18,000–21,600 bricks per shift, perfectly suited to meet the scaled production needs of small and medium-sized factories.
• Multipurpose Functionality: By quickly changing molds, the machine can flexibly produce standard bricks, hollow blocks, porous bricks, permeable paving bricks, grass-embedded bricks, curbs, and many other types of products, catering to diverse applications such as wall construction, road paving, and landscape engineering.
• Broad Raw Material Compatibility: In addition to conventional cement and sand, the machine can accommodate large quantities of fly ash, slag, steel slag, construction waste, and other industrial solid wastes, reducing raw material costs and enabling environmentally friendly production.
