QT5-15 hollow block machine is one kind of the main part of the whole production line which can make various designs of hollow blocks, porous blocks, curbstone, pavement blocks, grass blocks, slope-protecting blocks, ring-tree blocks,etc. 1. Multi-fuctional: The machine can make difference products by changing mould, like hollow block, solid block , solid brick, paver, Kurbstone and so on. 2. Power-saving: when the machine is working, only the main machine is always on, other parts only works at regular intervals. 3. Quick speed: the male and female mould inserts and pulls out quickly with high-powered hydraulic pump. Meanwhile, all the processes like feeding concrete into female mould and preparing concrete are finished at the same time. 4. High quality: the switches and electronic is using CHNT and Omron brand. Mould is processed by heat treatment, carburization. 5. Easy operation: the main machine is operated by one person, and other processes will be completed automatically by electronics. Because the pressure of vibration is high, the materials needs less water. So the machine still can work under low temperature. 6. Quick stacking: The brick made by this machine is high density. The wet bricks could be stacked if raw materials is good. So you can save pallets and land.
