China Suppliers Factory for Plastic Parts: Angle Gauge Plates, EVA Rail Pads, and Plastic Bowls
Basic Information
These standard-compliant rail pads are core elastic components installed between the rail foot and base plate, responsible for absorbing wheel-rail impact, reducing vibration transmission and avoiding metal wear between contact surfaces. Each batch is attached with material test reports and compliance certificates to meet local railway operation approval requirements.
Customized Materials
- EPDM Rubber: For general heavy-haul and commuter lines.
- Thermoplastic Polyurethane (TPU): For 300km/h+ high-speed rails.
- High-Hardness Nitrile Rubber: For North American 40t axle load heavy-haul freight lines (AREMA Chapter 5 specifications).
Core Performance
- Impact Absorption: 25%~70% adjustable rate.
- Durability: Less than 10% permanent compression deformation after 10 million load cycles.
- Temperature Range: Operating capability from -40℃ to 70℃.
- UV Resistance: 500+ hours UV aging resistance for open-air lines.
Compatibility & Options
- Fastening Systems: Compatible with Pandrol Fastclip, Vossloh SKL series, and AREMA tie plate systems.
- Adjustability: Customizable thickness, hardness, and surface texture to fit different rail profiles and gauge adjustment demands.
- Vibration Reduction: Low-damping versions cut vibration transmission by up to 15dB for noise-sensitive urban transit.
Frequently Asked Questions
Q: What materials are used for these rail pads?
We offer three customized materials: EPDM rubber for general heavy-haul/commuter lines, TPU for 300km/h+ high-speed rails, and high-hardness nitrile rubber designed for North American 40t axle load heavy-haul freight lines.
Q: What fastening systems are these rail pads compatible with?
They are fully compatible with mainstream standard fastening systems, including Pandrol Fastclip, Vossloh SKL series, and AREMA tie plate systems.
Q: How do the rail pads perform under long-term cyclic loading?
They exhibit excellent fatigue resistance, maintaining less than 10% permanent compression deformation after 10 million load cycles.
Q: Can these rail pads withstand extreme weather conditions?
Yes. They have an operating temperature range from -40℃ to 70℃ and feature 500+ hours of UV aging resistance for reliable performance on open-air lines.
Q: Are there custom options for noise-sensitive areas?
Yes, we provide low-damping customized versions for urban transit lines that can reduce vibration transmission to surrounding areas by up to 15dB. Thickness, hardness, and surface texture can also be customized.
Q: Do you provide quality certification for railway authority approvals?
Yes, every batch is delivered with material test reports and compliance certificates to meet local railway operation approval requirements.
