Plant Walkthrough

Six production zones, one continuous flow

A bus enters as steel coils and laser-cut blanks, and leaves as a road-worthy electric coach — every step happens inside this site.

Fabrication Bays

Trumpf & Prima 5-axis 3D laser cutting, HSG 2D laser, plasma cutting (3 × 13 m) and stretching machines feed precision blanks into the bus build line.

Robotic Body Shop

Robotic welding cells with dedicated jigs and fixtures deliver consistent body-in-white quality across steel and aluminium structures.

Press Shop

ISGEC MPS press line (350–600 T) handles structural panels in-house — feeding the same Tier-1 grade sheet metal PSR ships to leading OEMs.

Paint & Pre-treatment

Three dedicated paint booths with ovens and eco-friendly pre-treatment chemistry for corrosion resistance and long-life gloss finishes.

Trim & Final Assembly

Interior, seating, glazing, lighting and HVAC integration with five overhead cranes managing sub-assembly flow across the line.

Quality & Roadworthiness

Shower-test cabin, structural & electrical QA, plus an on-site roadworthiness loop where every bus is signed off before dispatch.
