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 materials enterprises. Integrating mechanical, hydraulic, and electrical control systems, it boasts stable and reliable performance, high production efficiency, and flexible product adaptability, making it the preferred model for standard brick factories and municipal building materials suppliers.

I. Core Process and Automation Configuration

The QT4-15 employs a vibration-pressure composite molding process, combining high-frequency vibration with hydraulic pressure to quickly and evenly compact concrete raw 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 linkage across the entire process—material feeding, vibration, pressing, demolding, and brick discharge—and can seamlessly integrate with batching machines, mixers, conveyors, and automatic palletizers to form a fully automated production line, significantly reducing reliance on manual labor and lowering labor intensity while achieving standardized, large-scale production.

II. Technical Parameters and Performance Advantages

• The equipment features a high-strength integral welded frame, offering excellent vibration resistance and durability, 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 Production Efficiency: 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 per cycle, resulting in 18,000–21,600 bricks per shift, perfectly suited to meet the scaled production needs of small and medium-sized factories.
• Multipurpose Capability: By quickly changing molds, the machine can flexibly produce standard bricks, hollow blocks, porous bricks, permeable paving bricks, grass pavers, curbs, and many other types of products, catering to diverse applications such as wall construction, road paving, and landscape engineering.
• : In addition to conventional cement and sand, the machine can accommodate large quantities of industrial solid wastes such as fly ash, slag, steel slag, and construction debris, reducing raw material costs and enabling environmentally friendly production.

III. Applicable Scenarios and Comprehensive Value

With its high degree of automation, rapid production efficiency, stable product quality, and low operation and maintenance costs, the QT4-15 fully automatic block molding machine is well-suited for small and medium-sized building materials enterprises, municipal brick production facilities, and rural infrastructure construction projects. Its compact footprint and low investment in plant and infrastructure allow for quick establishment of standardized production lines, making it an ideal choice for startups and small-to-medium-sized brick factories seeking efficient, low-cost, and eco-friendly brick production, helping businesses boost capacity and market competitiveness.
