The NBM 4020 Concrete Block & Paving Stone Machine combines compact design with industrial-grade power to deliver reliable, high-quality concrete production. Built on the same advanced engineering principles as larger models, the NBM 4020 is a hydraulic block machine that offers efficiency, durability, and versatility for both small- and medium-scale manufacturers.
Operating within a 120–140 bar pressure range, this machine can produce 8 pieces of 20×40×20 cm concrete blocks or 20 interlocking paving stones per press cycle. Designed for continuous operation and low energy consumption, the NBM 4020 ensures consistent, high-density block formation in every cycle.
At the heart of the NBM 4020 lies a hydraulic compression system that ensures every block and paving stone meets precise density and strength standards. The hydraulic pressure evenly distributes force across the mold, compacting the concrete mix into durable, dimensionally accurate shapes.
The system works in harmony with printing pallets, which serve as the foundation for both pressing and drying. Once the concrete mix is compressed into the mold, it is pressed onto the pallet, forming a solid structure that is then left to cure naturally on the same base.
This process guarantees high structural integrity and uniform texture — essential for both load-bearing concrete blocks and decorative paving stones.
Despite its compact size, the NBM 4020 delivers exceptional output. In one press cycle, it can produce:
8 standard concrete blocks (20×40×20 cm)
20 interlocking paving stones
This efficiency makes it an ideal solution for businesses seeking high productivity in limited space. Whether you are producing hollow blocks, solid bricks, or interlocking pavers, the NBM 4020 adapts easily to your production goals.
The NBM 4020 belongs to the A+ (A PLUS) class of energy-saving machines. It integrates EFF3 class electric motors, which are engineered to reduce energy consumption while maintaining consistent performance.
This efficient energy profile lowers production costs and supports sustainable manufacturing practices — a must for today’s environmentally conscious construction industry.
By optimizing hydraulic flow and motor performance, the NBM 4020 minimizes energy waste while maximizing mechanical output, ensuring a perfect balance between power and efficiency.
Ease of use is a defining feature of the NBM 4020. The system offers Auto / Manual operation modes, giving operators full flexibility during production.
Its intuitive control panel allows easy program selection, making setup, adjustments, and operation straightforward even for new users.
In case of interruptions, the machine includes an innovative “stop, hold, and resume” function, allowing production to continue seamlessly from the point of pause.
Furthermore, the remote troubleshooting option via Internet provides quick diagnostics and service support, minimizing downtime and ensuring consistent productivity.
Every NBM 4020 unit is manufactured to meet international quality and safety standards, ensuring long-lasting performance and operator safety.
It fully complies with:
ISO 9001:2008 Total Quality Management System
CE Declaration of Conformity (European compliance)
