In this video, we present the QT15 Fully Automatic Paver Production Plant, a high-capacity solution engineered for the efficient production of premium concrete paving products.
Configured with a 1400 × 1150 mm pallet, the production line is currently manufacturing 200 × 100 × 60 mm rectangle pavers, producing 60 pieces per mould with stable quality and excellent consistency. Combining intelligent automation, advanced servo vibration technology, and a fully integrated production process, the QT15 is designed to help concrete product manufacturers increase productivity, improve product quality, and reduce operating costs. Complete Automatic Production Process
The production process begins with the automatic batching machine, where cement, aggregates, sand, water, and additives are weighed according to preset formulas. Accurate batching ensures every batch of concrete maintains consistent proportions, providing a stable foundation for high-quality concrete products.
The materials are then delivered to the planetary concrete mixer. Its powerful multi-directional mixing action produces a homogeneous concrete mixture with uniform moisture distribution, ensuring excellent workability before entering the forming process.
After mixing, the concrete is conveyed automatically to the block making machine through the material conveying system, providing a continuous and stable material supply while reducing manual handling.
QT15 Servo Block Making Machine
As the core of the production line, the QT15 Fully Automatic Block Making Machine is built for continuous industrial production.
The reinforced heavy-duty frame provides excellent rigidity under high-frequency vibration, ensuring stable operation and long service life.
The machine adopts a 1400 × 1150 mm pallet, allowing larger moulds and higher output per cycle. During this factory hot testing, the QT15 is producing 200 × 100 × 60 mm rectangle pavers, with an output of 60 pieces per mould, making it an ideal solution for large-scale paving block production. The integrated face-mix system enables manufacturers to produce decorative paving products with coloured surface layers while maintaining excellent bonding between the face concrete and base concrete. By simply changing moulds, the same machine can also manufacture interlocking pavers, Holland pavers, grass pavers, curb stones, hollow blocks, solid bricks, and many other concrete products.
Advanced Servo Vibration Technology
The QT15 is equipped with four sets of 7.5 kW servo vibration motors, delivering powerful, precisely controlled vibration throughout the forming process.
Unlike conventional vibration systems, the servo system automatically adjusts vibration frequency and amplitude according to different products and production requirements. Combined with hydraulic pressing, it distributes compaction force evenly across the entire mould area.
This results in:
Higher concrete density Improved compressive strength More accurate dimensions Better surface finish Reduced cement consumption Consistent product quality throughout continuous production Reliable Hydraulic and Intelligent Control Systems
The high-performance hydraulic system delivers smooth pressure output and precise mould movement during every production cycle. Stable hydraulic control ensures fast response, reliable demoulding, and continuous operation even under demanding working conditions.
The electrical control system integrates a SIEMENS PLC with an intuitive touch-screen interface. Operators can easily monitor machine status, adjust production parameters, and manage the complete production process. Remote diagnosis and technical support also help minimize downtime and improve production efficiency. Automatic Handling and Curing System
After demoulding, the freshly formed pavers are transferred by the wet block conveyor to the automatic elevator.
The finger car then collects the pallets from the elevator, rotates them smoothly, and transports them into the curing chamber. This fully automated transfer process minimizes manual handling, improves production continuity, and protects fresh concrete products from unnecessary disturbance.
Inside the curing chamber, stable temperature and humidity provide suitable curing conditions, allowing the concrete to develop higher strength, improved durability, and more consistent quality.
Once curing is completed, the lowerator transfers the finished products from the curing chamber to the automatic cubing line, preparing them for packaging and shipment.
Automatic Cubing and Packaging
The automatic cubing system stacks finished pavers into neat and stable packages with reserved forklift openings, making transportation and warehouse handling faster and more efficient.
The automatic strapping machine securely binds every package, preventing movement during storage and transportation while reducing product damage.
This fully automated packaging process not only improves logistics efficiency but also significantly reduces labor requirements.
Factory Hot Testing
Before shipment, every HAWEN production line undergoes comprehensive factory hot testing using actual raw materials.
During testing, our engineers carefully inspect material feeding, mixing, vibration performance, hydraulic operation, mould movement, automatic conveying, curing transfer, cubing, and packaging.
The finished rectangle pavers demonstrate:
Accurate dimensions High density Smooth surfaces Clean edges Excellent consistency Stable product quality
Only after successfully completing all inspection procedures is the production line approved for delivery. HAWEN Machinery
