Features of Rail Plastic Dowel

Electrical Insulation

The primary function of rail plastic dowels is to provide electrical isolation between the rail and the fastening components, such as rail clips or screw spikes. This prevents the flow of electrical current and reduces the risk of interference with signaling and communication systems.

Corrosion Resistance

By isolating the rail from metal fasteners, rail plastic dowels help prevent galvanic corrosion that can occur when dissimilar metals come into contact in the presence of moisture.

Ease of Installation

Rail plastic dowels are easy to install. They are inserted into the pre-drilled holes, and the fasteners are then secured through the dowels and into the sleeper.

Compatibility

Dowels are designed to match the specific rail profile and fastener type used in the rail system. This ensures proper alignment and fit.

Fire Resistance

Rail plastic dowels are often designed to be fire-resistant, which is crucial for ensuring the safety of the rail infrastructure and nearby structures.

Applications of Rail Plastic Dowel

Alignment and Fastening

Rail plastic dowels are often used to align and fasten components in assembly processes. They can help ensure that parts fit together accurately and securely.

Panel and Board Assembly

Rail plastic dowels are used in the assembly of panels, boards, and partitions in various industries. They can help maintain the correct spacing and alignment of these components.

Electronic and Electrical Applications

Plastic dowels can also be used in electrical and electronic applications to secure and insulate components or to maintain precise spacing between them.

Automotive and Aerospace

Rail plastic dowels can be found in vehicle assembly and aerospace applications, helping with component alignment and attachment.

Decorative or Ornamental Work

In some cases, plastic dowels are used for decorative or ornamental purposes. They can serve as embellishments in art and craft projects.

Precautions for Installing Rail Plastic Dowels

● When transporting, loading, unloading, and stacking sleepers, the bolts should be screwed into the rail screw dowel. Or use the plastic plug to seal the dowel opening, in order to prevent debris from falling into the dowel.
● Before assembling the fasteners, the surface of the concrete turnout should be cleaned. The dowel should be clean and free of debris, the bottom of the dowel should not be blocked by debris or mud, and grease should be applied inside the dowel to prevent the bolts from rusting.
● When assembling fasteners, the inappropriate accessories must be polished and repaired. Hitting hard with a hammer which lead to damages to the fasteners and dowel is not allowed.
● When assembling fasteners, the bolt torque should be controlled at 250~300N·m.
● When assembling fasteners, do not use force rods and other tools to assemble, otherwise the acceleration force will exceed the maximum bearing capacity of the nylon rail screw dowel and damage the dowel.
