In recent years, the rapid development of metro and tunnel construction has driven strong demand for precast segment production. At the same time, wind turbine concrete towers are evolving toward larger and taller structures, placing higher requirements on dimensional accuracy and structural quality.
Product Overview
Our segment moulds are designed with an external vibration system and are compatible with both stationary production setups and automated production lines.
The structure is optimized for high-frequency operation, offering excellent rigidity, durability, and precision to meet demanding production conditions.
Key Advantages
1. High Dimensional Accuracy
Precision manufacturing ensures excellent dimensional consistency, meeting stringent project requirements.
2. Superior Surface Finish
The mould cavity is processed with high-precision machining, ensuring controlled surface roughness and improved concrete appearance quality.
3. Robust Structural Design
Critical areas are manufactured with high-quality welding processes, ensuring long-term stability and resistance to deformation.
4. Efficient Vibration System
The external vibration design provides uniform compaction, improving concrete density and overall segment quality.
5. Excellent Sealing Performance
Embedded sealing structure effectively prevents slurry leakage and ensures clean, well-defined edges.
6. Designed for Continuous Production
Suitable for high-frequency operation in automated lines, maintaining stable performance and consistent output quality.
Production Process
The standard segment production process includes:
Mould cleaning → Mould assembly → Release agent application → Reinforcement cage placement → Installation of embedded parts → Mould closing → Concrete pouring → Surface finishing → Film covering → Steam curing → Demoulding
Operation Recommendations
Clean the mould thoroughly before use, especially corners and grooves
Apply release agent evenly to avoid surface defects
Tighten bolts in the specified sequence to ensure structural stability and dimensional accuracy
Supporting Equipment
In addition to segment moulds, we provide complete supporting equipment solutions, including:
Reinforcement cage assembly fixtures
