These machines suit small-scale projects, self-building, or where electricity supply is inconsistent. Manual models can create interlocking, hollow, or solid bricks, with output closely tied to operator skill and effort.

Semi-Automatic Brick Machines

Semi-automatic brick machines combine manual input and automated processes. Models such as the QT4-25C use hydraulic systems to compact the mixture, achieving denser and smoother blocks with better consistency. These machines can manufacture a broader selection of products, including hollow blocks, solid blocks, and pavers. Production capacity ranges from 3,000 to 5,000 blocks per day, depending on the model and material flow. Operators control loading and unloading, while critical steps like pressing and moulding run automatically.

Fully Automatic Brick Machines

Fully automatic brick machines automate loading, mixing, moulding, and output collection. Machines like the LT4-10 and QT4-15 use PLC control systems for precise operation, achieving high efficiency and accuracy. These machines can produce up to 10,000 blocks per day, supporting large-scale construction and consistent output. They work with different block types, including high-strength interlocking, hollow, and autoclaved aerated concrete blocks, providing optimal uniformity and reducing labour needs.

Main Features and Components

Brick machines combine structural parts, control systems and interchangeable elements to support efficient block and brick manufacturing.

Frame and Structure

Every brick machine features a robust steel frame that supports operational loads. Reinforced structures in models like the QT4-25C and QT4-15 minimise vibration for improved block density and surface finish.

Hydraulic and Mechanical Systems

Hydraulic systems, present in semi-automatic and fully automatic machines like the QT4-25C and QT4-15, increase compaction force. Mechanical transmission systems appear in manual options such as the LT2-40, ensuring precise mould movement and consistent block size.

Control System

Fully automatic machines, such as QT4-15 and LT4-10, integrate programmable logic controllers (PLC). PLCs handle sequential tasks including material filling, pressing and ejecting, maximising speed and repeatability. Manual units rely on levers and hand controls, limiting output but requiring minimal technical skill.

Benefits of Using a Brick Machine

Brick machines increase production rates by automating labour-intensive tasks like pressing, compacting, and moulding. Fully automatic models such as the QT4-15 achieve outputs up to 10,000 blocks daily, which boosts efficiency for large construction projects. Manual machines like the LT2-40 support small-scale work by producing up to 1,000 bricks per day with minimal investment.

Consistent block quality results from precise mechanical operation. Hydraulic systems in machines such as the QT4-25C ensure uniform density and strength across blocks, reducing structural defects in finished buildings. PLC control systems found in advanced machines reduce human error, maintaining accuracy in materials handling and block dimensions.

Labour costs drop as fewer workers manage the production line. For example, a semi-automatic brick machine typically requires only two operators, while fully automatic setups function with minimal supervision. This resource reallocation frees skilled labour for other construction activities.

Customisation options come from interchangeable moulds and settings, allowing the production of multiple block types—such as interlocking, hollow, and solid blocks—without purchasing separate machines. Plants that produce AAC blocks with high thermal insulation or compressed earth blocks address project-specific requirements for efficiency and environmental performance.

Waste reduction occurs due to optimised raw material use and fewer rejected bricks. Quality control features integrated in fully automatic machines cut the proportion of defective units below 2%, reducing environmental impact and sourcing costs.
