A long-time white-goods customer moved this year to a single-source arrangement on the wire grades we produce for their oven grill assemblies.
The rationale on their side: tensile scatter between shipments from multiple vendors was creating downstream setup problems on their robotic bending cell. Standardising on us removed that variance.
On our side, it means we plan their material two weeks ahead and hold a small consignment near their plant. Simple, quiet arrangement. Working well.
