Introduction

Concrete sleeper moulds are crucial in the railway industry for manufacturing concrete sleepers, which provide stability and support for railway tracks. This article explains the process of creating these moulds, from material selection to the precise engineering steps involved.

Material Selection

The primary materials for concrete sleeper moulds include high-grade steel and cast iron, chosen for their durability and ability to resist wear and tear. The typical tensile strength requirement for these materials is above 400 MPa for steel and comparable for cast iron.

Design of Concrete Sleeper Moulds

The design of concrete sleeper moulds involves creating a cavity that meets precise geometric specifications. Typical dimensions for a standard sleeper mould are 2.6 meters in length, with sections allowing for track gauges of 1435mm or as required.

Key Design Parameters

• Exact track gauge conformity.
• Durability to withstand repeated use.
• Precision in cavity dimensions to ensure consistent sleeper output.

Manufacturing Process

Concrete sleeper moulds undergo a rigorous manufacturing process, which includes:

1. Metal Casting: Using high-quality steel or iron, cast into the rough shape of the mould.
2. Machining: CNC milling machines refine the dimensions and ensure smooth surfaces.
3. Stress Testing: Moulds are tested under simulated conditions to detect any structural weaknesses, adhering to a load capacity typically up to 25 MPa.
4. Surface Treatment: Anti-corrosive coatings are applied to prolong mould lifespan.
