Ⅲ. Technical Advantages
1.Four-Axis Servo Vibration System：Independent Drive for Precise Vibration Control
The T15 uses four servo motors to drive four eccentric shafts independently through flexible couplings. This drive arrangement coordinates shaft movement and allows vibration parameters to be adjusted to the requirements of the forming process.
The eccentric shafts are arranged symmetrically to counteract horizontal vibration forces while generating strong vertical vibration. By changing the eccentric angles, the system provides stepless vibration force adjustment from 0° to maximum amplitude.
Operators can adapt vibration settings to different concrete mix designs and product types. This flexibility supports controlled compaction, helping achieve the required product density and consistent molding results.
2. Air Bag Mould Clamping System：Secure Mold Positioning with Rapid Release
The T15 employs pneumatic air springs to clamp and release the mold. The system provides responsive operation, evenly distributed clamping force, and accurate positioning compared with conventional mechanical clamping arrangements.
Secure mold retention is particularly important during vibration, when the mold must remain correctly positioned throughout forming. The air bag mechanism also facilitates quicker mold release and changeover, reducing setup time between production runs.
3. Vibrating Tamper Head System：Quick-Release Mounting for Consistent Compaction
The tamper head is fitted with a pneumatic air bag locking mechanism that simplifies installation, removal, and secure attachment. This arrangement makes tamper head servicing more convenient and helps reduce interruptions during maintenance.
Vibration motors positioned on both sides of the tamper head work together with the main vibration system. Their coordinated action promotes even concrete compaction, supporting consistent density, dimensional accuracy, and surface finish across formed products.
4. Automatic Mold Changing System：Streamlined Mold Exchange for Multiple Products
The T15 incorporates an automatic mold changing device that carries out mold insertion, positioning, and removal through a controlled exchange process.
By automating these steps, the system reduces dependence on manual mold handling and shortens the changeover process. Manufacturers can switch production between compatible concrete product types by selecting the appropriate mold and configuration, supporting more flexible production planning.
5. Hydraulic Bottom Material Feeding System：Regulated Material Delivery for Uniform Mold Filling
Consistent concrete distribution begins before the vibration and pressing stages. The T15 uses a hydraulically driven bottom feeding mechanism to regulate cylinder movement and feeding force as concrete enters the mold cavities.
Controlled feeding helps limit material blockages, leakage, and uneven distribution. By promoting more consistent filling across the cavities, the system supports uniform forming conditions and dependable production flow.
6. 360° Rotary Anti-Arching System：Active Material Agitation to Reduce Feeding Interruptions
The T15 feeder uses an independently driven rotary mechanism to keep its wear-resistant mixing blades moving through a full 360° rotation. The continuous blade movement agitates the material during feeding and helps maintain its flow toward the mold.
Compared with conventional swing-type or vibration-based anti-arching devices, the rotary arrangement is designed to address stagnant areas and material bridging that can interrupt feeding. By helping reduce blockages, it supports a more consistent material supply during production.
The modular assembly allows worn mixing blades to be replaced without extensive disassembly. Low-noise operation and reduced blade wear are additional design characteristics that support routine maintenance and long-term operation.
7. Integrated Hydraulic Power Unit：Centralized Components for Simplified Maintenance
The T15 consolidates its hydraulic power supply, control components, and oil circuits into one compact hydraulic unit. This arrangement provides the hydraulic power needed for machine operation while reducing the complexity of the overall hydraulic layout.
Compared with a split hydraulic configuration, the integrated design requires fewer external piping connections, helping reduce potential leakage points. Consolidating the main components also simplifies inspection and routine servicing.
Responsive hydraulic actuation, stable pressure delivery, and efficient energy use support reliable operation throughout the concrete product forming process.
