QST8-15 Automatic Concrete Block Molding Machine
Compact and economical block machine with full automation and quick mould changes
The QST8-15 is a fully automatic block molding machine built as a compact, economical, and highly automated unit. It targets small and medium brick factories that want automation without the capital cost of a flagship line. The structure is tightly integrated, and the machine completes distribution, vibration compaction, and demolding on its own without heavy manual intervention. It works with crushed stone powder, sand, gravel, and cement, and it can take large amounts of fly ash, slag, steel slag, coal gangue, ceramic granules, perlite, and other industrial waste materials. By changing the mould it produces porous bricks, hollow blocks, ceramic granule insulation blocks, and composite insulation concrete blocks. The hydraulic proportional system is imported and runs efficiently at low energy draw, an imported PLC touch screen raises the level of automation, and an arch breaking distributor spreads porous brick fills evenly. Expanded high efficiency vibration shortens forming time, and a special high temperature heat treatment makes the moulds more wear resistant and robust.

A Compact Machine for Cost Conscious Plants
The QST8-15 is a fully automatic block molding machine built as a compact, economical, and highly automated unit. It targets small and medium brick factories that want automation without the capital cost of a flagship line. The structure is tightly integrated, and the machine completes distribution, vibration compaction, and demolding on its own without heavy manual intervention. That mix of low investment, high automation, and simple operation is what the design is built around, and it keeps a first automated line within reach for a plant that is still growing.
Technical Features
The hydraulic proportional system is imported and runs efficiently at low energy draw. An imported PLC touch screen with genuine electrical components raises the level of automation and simplifies operation. An arch breaking rapid distribution device is particularly strong on porous brick fills, where even spread decides block quality. Expanded high efficiency vibration shortens forming time and raises density in the finished product. A special high temperature heat treatment process makes the moulds more wear resistant and robust, which stretches mould life in daily production.
Raw Materials and Product Range
It works with crushed stone powder, sand, gravel, and cement, and it can take large amounts of fly ash, slag, steel slag, coal gangue, ceramic granules, perlite, and other industrial waste materials. One machine serves several products: by changing the mould it produces porous bricks and hollow blocks, ceramic granule insulation blocks, and composite insulation concrete blocks. Those products carry good thermal insulation performance and line up with current energy saving expectations, which helps a producer sell into projects that specify insulated wall units.
Main Specifications
The QST8-15 measures 9800 x 3600 x 2800 mm and weighs 14 T. Tray specification is 980 x 860 x 22 mm, forming cycle is 15 to 23 s, excitation force is 95 kN, and rated pressure is 31.5 MPa. Installed capacity is 44.9 kW, and the stacking machine carries a separate installed capacity of 3.0 kW. Vibration frequency runs 3800 to 4500, and the forming method is vibration pressurized forming.
Choosing It for a New Plant
For a producer moving from manual block making to a first automated line, the QST8-15 keeps the permit, power, and floor requirements modest while still giving full cycle automation. The wide raw material list lets a plant use locally available waste streams instead of buying in graded aggregate. The ability to change products with a mould swap means the same machine can follow demand between structural blocks and insulation units rather than sitting idle when one product slows.
