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."
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.

"One family, one foundry, in continuous operation since 1994. We still walk every new buyer's drawing through the shop floor ourselves before quoting."
