Recently, Qunfeng's "Supersonic" QS1300 paving brick production line was officially put into operation in Bangladesh. In a building materials factory located in the outskirts of the capital city Dhaka, rows of paving bricks rhythmically emerge from the "Supersonic" QS1300 intelligent brick-making machine. After being neatly stacked by the brick stacker, they are sent to the curing kiln for maintenance, with the whole process completed smoothly without much manual intervention.
