The QT4-24 Semi-Automatic Brick Making Machine is a flexible and high-value solution designed for small to medium-scale block-making operations. With its semi-automatic design, the QT4-24 enables manufacturers, distributors and contractors to deliver a wide range of concrete masonry products — from hollow blocks and solid blocks to pavers, interlocking units and curbstones.
1. Multi-Mould System – Broad Product Portfolio
One of the key strengths of the QT4-24 is its mould-change capability. By switching mould sets, the machine can produce different product types with minimal additional investment:
-
Hollow concrete blocks: Lightweight units with cavities to reduce dead-load and improve thermal/insulation performance. The QT4-24 can handle typical sizes (e.g., 400×200×200 mm) producing the same mould quantity per cycle.
-
Solid blocks: Dense, heavy units suitable for load-bearing walls and structural applications. The machine supports conversion to solid block moulds.
-
Paver bricks / interlocking blocks: Outdoor applications (driveways, walkways, patios) benefit from concrete pavers and interlocking designs. The QT4-24 supports paver moulds and interlocking block production.
-
Curbstones / kerbstones: For road-edge, landscaping and urban infrastructure use, the QT4-24 can produce curbstones when fitted with the correct mould.
-
Customized special shapes & sizes: The mould system allows manufacturers to cater to non-standard block/BIM demands, enabling markets with local dimension requirements or architectural finish demands.
2. Productivity & Quality Control
Despite being semi-automatic rather than fully automatic, the QT4-24 delivers significant output and consistent quality — important in export sales when you pitch to clients looking for ROI and reliability.
-
Technical specs: The host machine power around 13.45 kW for many models, with a typical mould-cycle of ~24-30 seconds.
-
Sample production capacity (indicative): For a size 400×100×200 mm hollow block, about 7 pieces per mould, 630-840 pcs/hour, or 5040-6720 pcs per 8-hour shift. For size 400×200×200 mm the output is approx 360-450 pcs/hour (2880-3600 in 8 hours).
-
The machine adopts vibration moulding (top & bottom vibration) and push-pull mould systems for improved compaction, block density and dimensional accuracy.
-
Compact workshop footprint: Many suppliers specify needing ~50-60 m² (or more depending on stacking/curing) and a small labour complement.
3. Raw Material & Operation Requirements
For optimal usage of the QT4-24 machine in your export pitch, highlight the following operational factors:
-
Mix-design flexibility: The machine handles cement, sand, crushed stone/stone-powder, fly-ash, slag etc as raw materials for block making.
-
Labour/operation: Typical line consists of one mixer operator, one host-machine operator, and 2-3 workers transporting pallets/blocks.
-
Ancillaries: Mixer (e.g., JQ350 model), belt conveyor, block trolley/stacker; power supply (380 V/415 V or local adaptation).
-
Footprint & stacking/curing: Curing area, stacking pallets, pallet size often 850×550 mm — important for your export clients’ layout planning.
4. Competitive Advantages for Export & Sales
As you position this machine to overseas buyers (Hazel — especially in Africa, Southeast Asia, Latin America), emphasize these differentiators:
-
Versatility: One machine covers multiple product types — hollow, solid, paver, curbstone — giving a broader product lineup to your client.
-
Lower capital investment: Compared to full automatic lines, the semi-automatic QT4-24 offers lower entry cost while still delivering decent output — useful for smaller factories or emerging markets.
-
Customisation: Mould sets can be adapted to local block size standards, shaped blocks or architectural finishes — giving your client a competitive edge.
-
Durability and serviceability: Emphasize heavy-steel frame, vibration system, quality moulds (manganese steel etc) — signal long operational life, less maintenance.
-
Scalability: Client might start with QT4-24, then later scale up to larger automatic lines; you as the supplier (via Raytone) can support that growth.
-
After-sales & spare parts: Given your role at Linyi Raytone Machinery Manufacturing Co., Ltd., stress your export service, spare-parts supply, training and installation support — key selling points for overseas clients.
