Sdu Plastic Dowel Pre-inserted railway dowel is a kind of embedded plastic railway fastener. It is mainly installed and fixed in pre-made products (such as concrete sleepers, bridges, buildings, etc.). After the dowels are being tied with the pre-made products, it is then ulitized by bolts or screws for fixing and fastening with other objects.
Railway dowel material: nylon fiberglass (PA66+GF), plastic (HDPE), cast iron, etc.
The production process is: injection molding by injection molding machine, which is the same as the railway insulator. Cast iron parts are produced by ductile casting iron.
Below are two kinds of materials that used for manufacturing rail screw dowels: HDPE and PA66 Nylon with glass fiber.
How much do you know about a railway insulator?Rail dowels serve as the foundation for the rail fastening system, pre-inserted into the concrete sleeper before the rest of the system is assembled. They guarantee a strong connection between the rail fastening system (including screw spikes, guide plates, and rail clips) and the concrete sleeper.Similar to rail pads or insulators, rail dowels also insulate the fastener parts from the ties, preventing electrical conductivity.
Rail dowels are typically made from materials like PA66 or HDPE, depending on the specific technical requirements of the fastening system.
Sud 25 rail dowel, Sud 26 rail dowel, Sdu9 rail dowel and SduS3 rail dowel are quite popular in the market.
