Thermoformed EV battery components
Indu Thermoformers manufactures thermoformed EV battery components in India — CCS (cell contacting system) trays, battery module covers, cell separation structures and BESS enclosure parts. Formed in halogen-free flame-retardant polycarbonate (UL 94 V-0 from 0.25 mm, CTI 600, 38 kV/mm dielectric strength) that we extrude in-house — so battery programmes get high-voltage insulation parts with material traceability from the pellet.
What we make
Materials

Why source from Indu
The right FR polymer
Halogen-free PC-FR — V-0 at 0.25 mm, CTI 600, 38 kV/mm — extruded in-house with lot traceability.
Fast iteration for fast programmes
Soft tooling in 2–4 weeks lets battery designs iterate between builds without steel-tool penalties.
Precision that assembles
5-axis CNC trimming against datums for cell, busbar and fastener locations.
Documentation battery OEMs need
COA, MTC, PPAP-level submissions and UL yellow-card material data.
Common questions
What is a CCS tray and why is it thermoformed?
A cell contacting system (CCS) tray locates busbars, FPCs and sense leads over the cells of a battery module. Thermoforming it in PC-FR gives precise cavity location, V-0 flame retardance and high-voltage insulation at a fraction of injection-mould tooling cost — and lets the design change as the module evolves.
Why does CTI 600 matter for battery parts?
CTI (comparative tracking index) measures resistance to surface tracking at high voltage. CTI 600 — the highest class — permits tighter creepage distances between conductors, letting battery designers pack cells and busbars closer while meeting IEC 60664 insulation rules.
Can you support BESS (battery energy storage) programmes?
Yes — module enclosure shells, compartment liners and separation structures in Shield FR PC and FR ABS, with the material documentation and repeatability grid-scale programmes demand.
