Commercial Engagement

How We Work With New Buyers

"Most of our long-term relationships started at an expo or through a referral — and that's still how we prefer to start. This page exists so you can check our capability before that first conversation, not replace it."

Meet us at an upcoming expo

We regularly exhibit and walk the floor at major industrial exhibitions across India and Germany.

Next: IMTEX / Elektrotec Pavilions

Illustrative example

An automotive Tier-2 supplier needed a re-sourced SG-iron bracket at IATF-audited quality after their previous vendor failed an audit. Rangan ran a trial pour, passed dimensional and material inspection within 3 weeks, and moved to production volume the following quarter.
