Overview
The QT4-15 fully automatic hydraulic brick machine is our flagship medium-sized, high-output, non-fired brick production unit. It is an intelligent concrete brick molding machine that integrates mechanical, electrical, and hydraulic systems. The machine operates fully automatically without the need for frequent manual intervention and is compatible with a wide range of raw materials, including sand and gravel, fly ash, slag, stone dust, and construction waste. It is the most popular, stable, and best-selling fully automatic model for medium-sized brick factories, startup brickyards, and infrastructure projects.
Core Advantages
1. Robust Structural Design
The main frame, vibration box, and material pressing assembly are manufactured in-house. With a well-balanced structural design, the machine remains stable and deformation-free during long-term operation.
2. Precision Vibration & High Molding Density
Equipped with a high-power, high-frequency 50kN vibration system, it ensures uniform vibration and strong penetration. This results in high brick density and hardness, with a finished product pass rate exceeding 99%.
3. Stable Hydraulic System
Features automatic pressure compensation and system interlocking. Pressure remains consistent across every molding cycle, eliminating issues with uneven compaction.
4. Forced Arch-Breaking Material Feeding System
Ensures uniform material distribution without dead zones and effectively mixes fine and coarse aggregates, solving the common problem of uneven density (dense on one side, loose on the other) found in standard machines.
5. Energy-Efficient, Durable & Low Labor Requirements
A fully automated production line requiring only 2–5 operators; offers low energy consumption and stable output.
6. Versatile Functionality: Produce a Full Range of Bricks by Simply Changing Molds
Without replacing the main unit, simply swap molds to produce all common brick types, including standard bricks, multi-hole bricks, hollow bricks, permeable bricks, curbstones, and interlocking pavers.
Brick Types Produced
By simply changing molds, the QT4-15 can produce a variety of brick types
• Solid standard bricks, supplementary bricks, and half-bricks
• Hollow bricks and multi-hole bricks in various specifications
• Municipal permeable bricks, paving bricks, and plaza pavers
• Interlocking slope protection bricks, I-shaped pavers, and grass pavers
-Curbstones and custom-shaped engineering bricks
No need to replace the machine, modify wiring, or alter the structure; mold changes are completed in half an hour, allowing for product switching at any time.
