Rail Plastic Dowel

Rail plastic dowel is also called rail plastic sleeve/plastic insert/concrete dowel/ concrete insert,.Railroad Plastic Dowel is a counter-party of Screw Spike, which is pre-inserted into the concrete sleeper. When we use the rail fastening system, the plastic railroad dowel performed as the fastening base. Our plastic dowel is made using either HDPE or PA66 + GF30% and the product color is available in white, black and dark brown.

Functions of the Rail Plastic Dowel

In a set of rail fastening system, 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.
