The hot testing of multicolor paver production on the Hawen QT7-15 block making machine, configured with a pallet size of 1150 × 750 mm, represents a critical validation stage prior to delivery to an Armenian client. This commissioning phase is not merely procedural; rather, it functions as a comprehensive performance audit, ensuring that the machine operates with precision, stability, and—most importantly in this case—exceptional multicolor blending capability.
1. Multicolor Surface System (Face-Mix Technology)
At the heart of this test lies the face-mix system, whose primary objective is to achieve superior multicolor surface effects. Unlike conventional paver production, where surface uniformity is the dominant criterion, this system emphasizes controlled randomness and aesthetic layering.
The multicolor performance is repeatedly stressed and verified throughout the testing process. The machine demonstrates its ability to:
Distribute pigments evenly while preserving natural variation Prevent color segregation during feeding and vibration Maintain consistency across batches despite deliberate color diversity
Such performance is indispensable for high-end architectural pavements, where visual differentiation translates directly into market value. The repeated emphasis on multicolor blending is therefore not incidental, but central to the machine’s technical identity and the client’s commercial objective. 2. Enhanced Machine Configuration for Versatility
The QT7-15 unit used in this test features a heightened frame structure, enabling the production of taller concrete elements, including curbstones in addition to standard pavers. This structural modification expands the application range of the equipment without compromising operational stability.
By accommodating both decorative pavers and functional roadside elements, the machine achieves a balance between aesthetic versatility and infrastructural utility, thereby increasing its return on investment for the end user.
3. Material Feeding and Forming Stability
Beyond the face-mix system, the base material feeding system operates with consistent throughput and precise proportioning. The synchronization between base mix and face mix ensures that:
The structural integrity of the block is not compromised by the decorative layer Layer adhesion remains strong under high compaction forces Output remains stable during continuous operation
This coordination reflects a well-engineered integration of subsystems, minimizing operational variance and maximizing yield efficiency. 4. Vibration System: Uniform Compaction with Reduced Resistance
Hawen Machinery adopts a four-shaft vibration box design, with eccentric blocks positioned externally. This structural arrangement significantly reduces internal resistance during vibration, allowing energy to be transmitted more efficiently to the mold.
As a result, the system achieves:
More uniform compaction across the entire product surface Lower cement consumption due to improved density Enhanced production efficiency without increasing energy input
Such a design is particularly beneficial for multicolor pavers, where uneven compaction could otherwise distort surface patterns. 5. Intelligent Control System for Process Optimization
The machine integrates a SIEMENS S7-200 PLC with an intuitive touch interface and remote monitoring functionality. This control architecture enables operators and engineers to:
Through this system, Hawen ensures that production quality remains consistent, even under varying working conditions, while also providing a foundation for predictive maintenance and long-term reliability. 6. Hydraulic System: Precision and Durability
The hydraulic station is engineered with internationally recognized components, incorporating Japanese YUKEN proportional and directional control valves, alongside a high-performance American ALBERT hydraulic pump.
This configuration delivers:
Precise control over pressure and flow Strong load-bearing capacity during high-frequency operations Long-term durability under continuous industrial usage
The result is a hydraulic system that supports both the delicate requirements of multicolor surface formation and the robust demands of heavy-duty block production. 7. Mold Engineering and Cross-Platform Compatibility
Hawen Machinery designs molds compatible with leading global brands such as MASA, HESS, ZENITH, POYATOS, BESSER, and TIGER. Manufactured in accordance with original specifications and subjected to rigorous heat treatment, these molds ensure:
Accurate dimensional conformity Smooth demolding processes Consistent product quality across different machine platforms
This compatibility not only enhances flexibility but also reinforces Hawen’s position within the global block machinery ecosystem. Conclusion: From Functional Testing to Value Creation
This hot testing process transcends routine inspection; it is a decisive demonstration of how engineering precision translates into market-ready value. The persistent emphasis on multicolor blending performance reflects a strategic understanding of evolving industry demands, where aesthetics and functionality converge.
At Hawen Machinery, innovation is not confined to isolated components but is embedded within an integrated system that harmonizes design, control, and execution. The QT7-15, as evidenced in this Armenian project, is not merely a production unit—it is a platform for manufacturing differentiation, enabling clients to compete not only on volume, but on visual sophistication and product excellence.
In an increasingly competitive construction materials market, such capability does not simply meet expectations—it redefines them.
