Railway & mass transit
Railway & transit thermoforming
Rail and bus interiors need large flame-retardant parts to EN 45545 fire standards — and thermoforming is the economical way to make them. Indu Thermoformers forms interior panels, ducts, ceilings and seat components in EN 45545 HL3 and UL 94 V-0 grades, on the largest thermoforming bed in India.
Large, fire-rated interior parts
Rail and bus programmes need big interior panels, ducts and ceiling sections in materials that pass EN 45545 fire, smoke and toxicity requirements. Injection moulding these at rail volumes is uneconomic; thermoforming forms them at cabin scale on soft tooling, and our large bed means panels other formers must split and join, we form whole — stronger and cleaner.
HL3 and V-0 materials for transit
We form Shield FR ABS and halogen-free FR polycarbonate in EN 45545 HL3 and UL 94 V-0 grades into interior wall and ceiling panels, HVAC ducting, seat-back shells, window masks and equipment covers. Weight savings versus metal carry through the vehicle's service life, and documentation supports transit qualification.

Materials for railway thermoforming
Why Indu for railway thermoforming
In-house sheet extrusion
We extrude the sheet we form — grade, colour and thickness controlled from the pellet, with no outside vendor in the loop.
Largest bed in India
Thin- and thick-gauge lines, including the largest thermoforming bed in the country for oversized parts.
Tooling in 2–4 weeks
Moulds and trim fixtures designed and cut in-house on 5-axis CNC — fast, and cheap to revise.
ISO 9001 & full docs
8-gate inspection with COA, MTC, FAIR and PPAP-level documentation on request.
Frequently asked questions
Do you offer EN 45545 HL3 fire-rated materials?
Yes — Shield FR ABS and halogen-free FR polycarbonate in EN 45545 HL3 and UL 94 V-0 grades, with documentation to support rail and transit qualification.
Can you make large rail interior panels?
Yes — we run the largest thermoforming bed in India, so oversized wall, ceiling and duct panels can be formed as single parts rather than split and joined.
Why thermoform rail interiors instead of injection moulding?
Rail volumes are low and parts are large, so injection tooling rarely pays back. Thermoforming forms cabin-scale parts on soft tooling in weeks, at a fraction of the cost, while cutting weight versus metal.
