The QI4-26C brick making machine (commonly written as QTJ4-26C) is a semi-automatic concrete block and brick production machine used for manufacturing different types of bricks such as hollow blocks, solid bricks, paving blocks, and interlocking bricks. It is designed for small to medium-scale production and combines mechanical, electrical, and vibration systems to produce high-quality bricks. The machine typically consists of a main forming unit (host machine), mould system, vibration system, motor, control panel, material hopper, and sometimes supporting equipment like a mixer and conveyor. It can use raw materials such as cement, sand, gravel, fly ash, and industrial waste to produce strong and uniform blocks.

In operation, raw materials are first mixed (usually in a separate mixer) and then fed into the machine’s hopper. The material is distributed into the mould box either manually or automatically. Once the mould is filled, the machine applies strong vibration and pressure simultaneously—the lower mould vibrates while the upper mould compresses the material. This combination compacts the mixture tightly, forming dense and high-strength bricks.

After compaction, the mould is lifted, and the freshly formed bricks are released onto pallets. These bricks are then moved (manually or using a trolley/conveyor) to a curing area where they are left to harden naturally. The machine repeats this cycle, typically taking about 20–30 seconds per cycle, allowing continuous production.

Overall, the QI4-26C brick making machine is valued for its ease of operation, ability to produce multiple brick types by changing moulds, and high production efficiency, making it suitable for construction businesses and block-making enterprises.
