QT12-15 Concrete Block Machine
Model QT12-15 block making machine is the largest model in the Lontto QT series, with the highest capacity of block production, producing 12pcs/mould(400*200*200mm), only 10-15s can get the block, it is operated without worker.
It is equipped with a Siemens PLC control system. And all the mould can be made by customers’ drawings. The key parts are famous brand electrical parts, such as Schneider, to guarantee good quality. So if you need our highest-capacity and fully automatic block making machine, the model QT12-15 is the best choice for your block production project.

Technical Features of QT12-15 Block Machine :
- Recycle material feeding system: Economize in material for different or same density products.
- Reliability design of the machine frame, made of super-strength steel and by special welding technology, the imported elements are applied widely, so that the stability and reliability of the machine in long term running are insured.
- Mould frames are made of 55# Manganese steel, and the tamper head is made of 16# manganese steel. After carburizing, the hardness can reach 60 degrees, lifespan can use over 100000 times. Standard brick mould can double-side use, lifespan can use over 120000 times.
- Hydraulic parts and seals parts on hydraulic pressure system are from Japan or Taiwan, which protects pressure discharging or leakage.
- Multi use; Strong performance; The many kind of products with difference form and size can be made when use the difference mold, such as wall block, honeycomb type block, road block and slope block.
