The rail pad, originally called sole plate, is used when rail is attached to concrete, rather than timber, ties or sleepers. Rail pads function to reduce fatigue cracking of the concrete ties, believed to be driven by impact and vibration from the passing train.
As a professional manufacture of rail fasteners,GNEE RAIL can produce various types of rail pads for different rail standards, such as UIC54, UIC60, BS80lbs, BS100lbs, etc. Moreover, we can arrange customized production of rail pads according to drawings or samples.
GNEE RAIL's Manufacturing Process of rail pads
- Preparation of rubber compound
- Mixing is carried out on a two-roll mill or in an internal mixer. In the case of an internal mixer, it can be done in a single-stage or double-stage mixing where the masterbatch, which was earlier prepared in the internal mixer, is finalized by adding curatives on a two roll mill.
- Shaping and curing
- Compression or Injection moulding
- Trimming of finished products
- Ready for use
