Features
Rail Plastic Dowel, also known as railway plastic dowel or nylon dowel, is an important part of the railway track fixing system. It is a kind of opposite fastener that is pre-inserted into the concrete sleeper, usually assembled with sleeper screws, guides and rail clamps and other components to secure the rail. Its main function is to ensure a good connection and linkage between the track fastening system and the concrete sleeper, while insulating the fastener components with the sleeper to improve the stability and safety of the entire railway line.

Function and application
Fastening function
Rail Plastic Dowel plays a key fastening role in the railway track fastening system, working in concert with other fastening components to ensure that the track is securely fastened to the concrete sleeper.
Insulation
Due to its good insulation performance, Rail Plastic Dowel can effectively isolate the current conduction between the fastener parts and the sleeper, reducing potential safety risks caused by electrical failures.
Improved stability
The use of Rail Plastic Dowel can enhance the overall stability of the track fastening system, reducing the damage to the track and sleeper caused by vibration and shock caused by train operation.
Widely used
the product is widely used in railway, subway, light rail and other rail transportation fields, especially in high-speed railway and heavy-haul railway, its importance is more prominent.
