Sleeper moulds

At CAVITY, our decades of expertise in prestressed monoblock sleeper production drive the development of high-quality, precision-engineered moulds for the railway industry. With over 5,000 moulds exported worldwide, we deliver solutions that combine efficiency, durability, and superior performance.

Proven Expertise & Global Reach

Our moulds are developed and tested in our dedicated mould-building department, ensuring they meet the highest standards of quality. After rigorous testing, serial production is carried out in our advanced Asian facilities, managed directly under Belgian supervision—guaranteeing consistent, world-class results.

Innovative Design & Robust Performance

Each mould is equipped with a reinforced reaction frame, engineered to absorb pretension forces. This ensures that both the mould and the sleepers remain free from cracks or deformations, delivering long-term reliability.

Flexible Solutions for Diverse Needs

Our moulds are fully compatible with interchangeable rail seats from leading systems, offering the flexibility to adapt to your specific requirements.
