Business Solution Overview
High Production Throughput: With a 15–25 second moulding cycle and up to 7 pieces per mould, the QT4-16 can produce thousands of blocks per shift, supporting high-volume commercial supply contracts.
Reduced Labour Dependency: Automatic material feeding and automatic stacking minimise manual intervention, lowering ongoing labour costs and improving consistency across production runs.
Product Flexibility: Interchangeable moulds and an optional colour feeding system allow the same line to produce hollow blocks, solid blocks, standard pavers and premium coloured paving stones.
Integrated Line Efficiency: Combining mixing, conveying, forming and stacking in one configured line reduces material handling bottlenecks and supports continuous production flow.
Durable Output Quality: The 16 MPa hydraulic system delivers high compaction pressure, helping produce dense, accurately formed blocks suited to structural and decorative applications.

Why Choose QT4-16 Automatic Hydraulic Block Making?

Advanced PLC Automation

Fully automatic production system with PLC control for consistent, repeatable block forming with minimal operator intervention.

High-Pressure Hydraulics

16 MPa hydraulic system delivers high compaction pressure, producing dense and durable concrete blocks and pavers.

Fast Moulding Cycle

15–25 second cycle time supports high production throughput for commercial block manufacturing.

Interchangeable Moulds

Quickly switch between moulds to produce different block and paver sizes on the same machine.

Automatic Stacking

Integrated stacker automatically stacks freshly formed blocks layer by layer, reducing manual handling after moulding.

Optional Colour Feeding

Add the colour feeding system and JQ350 colour mixer to produce coloured paving stones with a decorative surface layer.
