QT4-15C Automatic Brick Molding Machine is the newly upgraded fully automatic programmable block equipment independently developed by Shandong Hongfa Machinery. Optimized targeting small and medium brick factories worldwide, the machine integrates PLC intelligent control, hydraulic drive and patented high-frequency table vibration technology. It supports various waste raw materials including fly ash up to 70% mixing ratio, and can produce hollow blocks, standard bricks, eight-hole grass bricks, curbs and interchangeable pavers by replacing molds. The whole production line realizes fully automatic pallet feeding, material distributing, vibration pressing and demolding. With compact structure, low power consumption of only 21.8Kw and stable 24-hour continuous running performance, it is an ideal eco-friendly brick production equipment for domestic and overseas building material manufacturers.
The machine boasts outstanding raw material adaptability. Fly ash, slag, gangue, stone powder and construction recycled aggregates can all be used as main raw materials, with fly ash proportion reaching 70%. Equipped with quick-change molds, one single machine manufactures hollow blocks, standard solid bricks, eight-hole grass bricks, permeable pavers, road curbs and slope protection bricks to meet diversified order demands, effectively cutting factory investment costs.
Equipped with industrial PLC + touch screen human-machine interface, combined with contactless proximity switches for real-time monitoring, integrating machinery, electricity, optics, hydraulic and high-frequency vibration technologies. Three operation modes (manual / single cycle / continuous automatic) are available. The full production process of pallet feeding, distributing, pre-vibration, hydraulic pressing and synchronous demolding runs automatically with only one operator required, greatly lowering labor intensity.
All key hydraulic valves, sealing parts and electrical fittings adopt imported original parts or well-known domestic brands. Complete electromechanical linkage inspection is finished before delivery. The machine rarely generates oil leakage, circuit failure or mechanical jamming under long-term continuous operation, featuring stable performance and ultra-low failure rate for remote overseas brick plants.
Adopts self-developed exclusive vibration box with dual synchronous vibration motors, vibration frequency 50-70Hz and strong excitation force of 380kN. Combined pre-vibration & pressure molding makes bricks dense without hollow layers. Finished blocks achieve tensile strength above 15MPa, with excellent frost resistance, impermeability, heat and sound insulation, precise size and complete edges.
Forced synchronous lifting structure ensures the pressure head and mold move up and down at uniform speed. Slow demolding avoids scratch, chipping and cracking of green bricks, keeping consistent thickness of all products. The finished product rate exceeds 98%, reducing raw material waste and brick repairing labor.
Molding cycle only 15-20 seconds, producing 4 hollow blocks or 28 standard bricks per mold. Total machine power is merely 21.8Kw, saving much electricity compared with same-type devices. Fresh bricks support natural air curing without steam kilns, largely lowering factory construction and operation cost.
