FAQ

What is SMC rail transit part? What core components does it consist of?

SMC rail transit part is a high-performance thermosetting composite component specially developed for the rail transit industry, made of unsaturated polyester resin (or epoxy resin), glass fiber (content 30%-50%), low-shrinkage additive (LSA), flame-retardant additive, anti-aging additive and other auxiliaries, formed by high-temperature and high-pressure compression molding. It integrates the advantages of lightweight, high strength, excellent insulation, flame retardancy and weather resistance, and is widely used in key parts of rail transit vehicles and lines, providing safe and reliable support for the stable operation of rail transit systems.

What are the common application scenarios of SMC parts in the rail transit industry?

SMC parts are widely used in rail transit vehicles and line facilities, covering multiple core scenarios: ① Vehicle interior and exterior parts: Window frames, carriage wall panels, ceilings, seats, tea table tops, bathroom components (washbasins, waterproof chassis); ② Electrical system components: Cable troughs, electrical control cabinets, battery boxes, insulation brackets, traction system enclosures; ③ Track line components: Return rail supports, signal responder enclosures, cable brackets, manhole covers along the line; ④ Special functional parts: Anti-collision components, sound insulation panels, vibration-damping brackets, which are suitable for high-speed rail, subway, intercity railway, tram and other rail transit types.
