China Custom Qt12-15 Auto Concrete Block Making Machine
Products Description
In the sequence of block forming machines, the QT12-15 is not simply a "bigger size." It redefines the standard for high‑output equipment, built upon all the technical accumulation of the QT10-15.
Compared to the QT10-15, the QT12-15 requires about 30% more equipment investment, but increases output by 35% and reduces unit energy consumption by approximately 15%. This means that every extra dollar you invest is recovered in a shorter time through higher production and lower operating costs.
UNIK Machinery was founded in 2008, with a core team of engineers who have decades of experience in the brick machine industry. We consistently uphold the philosophy that "our success is only achieved when our customers succeed." The QT12-15 is a concentrated embodiment of this philosophy – not simply piling up production capacity, but creating real value for customers in every technical detail.

Main features

The QT12-15 is a true all‑rounder. By changing molds, it can produce almost all mainstream concrete products:
Standard solid bricks, hollow blocks, perforated bricks, paving bricks, curbstones, grass planting pavers, interlocking blocks, I‑shaped bricks, insulating blocks, and more.
What does one machine, multiple products mean? It means you don't need to buy a separate machine for every product type. Whatever the market demands, you can produce it. This flexibility is the most underestimated value of high‑output equipment.

Process
Customisation is the default option for the QT12-15
"Customisation" is not an option for the QT12-15 – it is its basic configuration.
We can customise the mold dimensions to your requirements – any shape, any size.
We can customise the voltage to your local power conditions – 380V, 415V, 440V, and other common voltages.
We can customise the recipe parameters according to the brick types you produce – stored in the PLC and recalled with one click when changing production.
We can even customise the entire production line layout to your factory – from batching, mixing, and forming to palletising, fully integrated.
