Hot testing for Hawen QT12 paver block making machine

In this video, we showcase the full working process of our QT12-15 automatic block making machine during hot testing for a UAE client. You can clearly see how the machine delivers stable performance, precise forming, and high output efficiency in real production conditions.

 Production Process Overview:
✔ Material Feeding – Raw materials are automatically delivered into the hopper with consistent and controlled flow
✔ Pre-Press – The mixture is pre-compacted to ensure better density and forming quality
✔ Face Material Feeding – High-quality face mix is added for pavers to achieve a smooth and attractive surface
✔ Automatic Forming – The machine completes vibration and pressing in one cycle, ensuring strong and uniform blocks

 Key Technical Highlights:
• Pallet size: 1400 × 950 mm
• Paver size: 200 × 100 × 60 mm
• Output capacity: 48 pcs per cycle

• Stable hydraulic system with precise control for consistent product quality

Design Features of QT12-15 Block Making Machine Production Line

1. Hydraulic Station – Stable and Precise Power Control

The hydraulic system is equipped with high-performance pumps and proportional valves, ensuring smooth and accurate pressure control throughout each production cycle.
It provides strong and stable power support for pressing, vibration, and demolding processes, ensuring high-density blocks and consistent quality.

2. Intelligent Control System – Siemens PLC Automation

The production line adopts an advanced Siemens PLC control system with a touch screen interface for easy operation.

Key advantages include:

· Real-time monitoring of production status

· Fully automatic parameter adjustment

· Fault diagnosis and alarm system

· Stable and consistent production control

This ensures high automation and reduces operator dependency.

3. Mechanical System – Heavy-Duty and Durable Structure

The QT12-15 block making machine mechanical system is built for long-term continuous operation.

Main features:

· Strong vibration table for uniform compaction

· High-precision mold frame for quick mold change

· Wear-resistant mechanical components for long service life

· Stable frame design to reduce vibration loss and maintenance cost

 Offline Automatic Cuber System – Higher Automation Level

The QT12-15 block making machine production line includes an offline automatic cuber system, which significantly improves the overall automation level of the entire production process.

After the curing stage, the system automatically:

· Collects finished blocks

· Arranges and stacks blocks layer by layer

· Forms stable cubic pallets ready for forklift handling

By including the cuber system in the production line, manual handling is greatly reduced, stacking efficiency is improved, and the whole production process becomes more automated, continuous, and efficient.

This QT12-15 block making machine model is designed for high-volume production of hollow blocks, solid blocks, and interlocking pavers. It features strong vibration force, reliable automation, and excellent dimensional accuracy, making it ideal for large-scale construction material factories.

 Whether you are expanding your block production line or upgrading your existing system, this machine offers a balance of efficiency, stability, and product quality.
