Product Details

Product Description

1.Product Name: Plastic dowels

The plastic dowel can be considered as the fastening foundation, as it needs to be pre-inserted into the concrete sleeper separately before assembling the rail fastening system parts. It is used to guarantee the good connection and linkage of the rail fastening system with the concrete sleeper, with screw spikes or bolts.

On the other hand, similarly as the rail pad or rail insulators, the plastic insert’s another function is to insulate the fastener parts from the ties. Therefore, the quality of this small pre-inserted part into the concrete sleeper, especially its strength and fatigue life, is of great importance to the whole rail line.
