What is a rail pad?
Rail pads can prevent rail sleeper abrasion and the crushing of the sleeper under the rail foot. Rubber rail pads are normally designed to a specified load-deflection characteristic. The initial stiffness of the rail pad is designed to be low so that that their deformations under the springs toe loads is quite substantial.
Rail pad under the track can achieve such functions
Distribute load to a large surface
Eliminate load concentration and fatigue stress
Absorb the uneven surface contact between rail and support
Weaken rail noise and vibration
Seal the gap between the bottom of the track and the top of the sleeper
Reduce the wear of steel rail and rail sleeper
Rail Pads production process
Rubber compound preparation
Mixed by an internal mixer or a two-roll mill. In terms of the internal mixer, the raw materials are processed by single or double stage, during which the masterbatch prepared ahead of time is finalized by adding curing agents to the twin roll mill.
Shaping and curing
Compression or Injection molding
End products trimming
