Product Details & Advantages

Siemens PLC Control System
 
The QT5-15 block making machine features a Siemens S7-1200 series PLC control system with PROFINET industrial protocol, enabling fully automated production with millisecond-level response precision. This industrial automation solution offers:
Ⅰ. Integrated HMI (Human-Machine Interface) with 10.1" touchscreen for real-time parameter visualization and adjustment;
Ⅱ. Advanced PID algorithm for closed-loop control of vibration frequency (0-100Hz adjustable) and hydraulic pressure (0-25MPa);
Ⅲ. Data logging function supporting USB export of production records (cycle time, output, error history).
 
Featuring IP65 protection for reliable -20°C to +60°C operation, with redundant circuits for power failure protection and OPC UA integration for Industry 4.0-ready SCADA connectivity.
 

Siemens Vibration Motor
 
Featuring Siemens vibration motors that deliver exceptional performance and reliability, our system ensures precise, high-frequency vibrations for optimal block compaction. These industrial-grade motors provide: 
Ⅰ. Consistent power output for uniform density in every block; 
Ⅱ. Energy-efficient operation reducing production costs;
Ⅲ. Extended service life with 30% longer durability than standard motors.
 
The German-engineered technology guarantees vibration stability even under continuous heavy-duty operation, significantly improving product quality while lowering maintenance requirements.

Japan Yuken Hydraulic Valve
 
The QT5-15 block making machine features Japan's precision benchmark Yuken hydraulic valves, ensuring ultra-reliable performance in high-demand production, with advantages including:
Ⅰ. Smooth & Precise Control – Optimized flow regulation for consistent brick density
Ⅱ. Extended Lifespan – Hardened components resist wear, reducing maintenance costs
Ⅲ. Energy Efficiency – Low internal leakage design cuts power consumption by up to 15%
 
With Yuken's industry-leading 25MPa pressure rating and ISO 4401 compliance, the system maintains stable operation even under continuous heavy loads.

Precision Mould System

Molds are crafted from wear-resistant manganese steel via precision machining and multi-stage hardening; special molds use wire cutting, ensuring superior performance in high-intensity production. Key advantages:

 Ⅰ. Precision Engineering  – CNC-machined to ±0.02mm tolerance with mirror polishing, guaranteeing flawless brick formation and smooth demolding.

Ⅱ. Unmatched Durability –Through-hardening + special heat treatment (HRC58-61) doubles wear resistance; modular design slashes maintenance by 60%.

Ⅲ. Proven Longevity – 80,000+ cycles with sustained precision; laser-hardened critical zones boost lifespan to 1.8x industry standard.

ISO 9001 & CE compliant with advanced customizable heat treatment capabilities for optimized performance with all specialty concrete and recycled materials.
