When setting up or expanding a precast concrete factory, seeing a block machine in actual production is the best way to evaluate its efficiency, stability, and build quality.
In this video walkthrough, we demonstrate our QT6-15 Automatic Concrete Block Making Machine in action—showing how a single operator can control the entire batching, hydraulic pressing, and automatic stacking process with precision.
Watch the Live Operation: QT6-15 in Action
In the video above, you can observe the seamless workflow of the QT6-15 block production line:
1.Automated Material Feeding: Aggregate and cement mortar are evenly distributed into the mold box via the horizontal feeder.
2.Hydraulic Vibration Compaction: High-frequency vertical vibration combined with heavy hydraulic top-pressure achieves superior block density in seconds.
3.Smooth Demolding: Formed hollow blocks emerge cleanly without cracks or deformation.
4.Automatic Stacking & Transport: Green blocks are transferred directly onto pallets for curing via the chain-driven stacker system.
Key Features of the QT6-15 Automatic Block Machine
Why is the QT6-15 model one of the most popular choices for medium-to-large concrete brick plants worldwide? Here are its core design advantages:
1. Smart PLC Control Desk (Siemens/Schneider)
As seen in the video, the entire production line is managed by a centralized PLC intelligent control desk. The operator can easily monitor parameters, adjust vibration frequency, and switch between automatic and semi-automatic modes with a touch of a button.
2. High-Pressure Hydraulic System
Equipped with proportional hydraulic valves, the machine delivers up to 15-21 MPa of hydraulic pressure, ensuring that every brick meets strict international standards for load-bearing and compressive strength.
3. Multi-Purpose Molding Capabilities
By simply changing the wear-resistant alloy mold, the QT6-15 can produce a wide variety of precast concrete products:
-
Hollow Blocks: 400×200×200mm, 400×150×200mm, etc.
-
Solid Bricks & Paving Stones: Standard wall bricks, interlocking pavers, grass pavers.
-
Municipal Curbs: Roadside curbstones and drainage blocks.

Production Capacity & Daily ROI Estimation
The QT6-15 offers an optimal balance between initial investment cost and daily output. Here is a daily capacity snapshot based on an 8-hour working shift:
-
Standard Hollow Blocks (400×200×200mm): 6 pcs/mold ➔ 9,000 – 11,500 pcs/day
-
Interlocking Pavers (200×100×60mm): 16 pcs/mold ➔ 23,000 – 30,000 pcs/day
-
Standard Solid Bricks (240×115×53mm): 32 pcs/mold ➔ 45,000 – 55,000 pcs/day
Investment Insight: With a daily yield of over 10,000 hollow blocks, plant owners can typically achieve full capital recovery within 4 to 6 months under stable market demand.
