Customer Profile
Industry: Fortune 500 industrial equipment | Location: Chicago, USA | Order: 18-month ongoing, 40+ part numbers, quarterly production runs
The Challenge
“We had a supplier who nailed the first order. Then quality decayed — parts started coming in with burrs, threads out of spec, surface finish that changed batch to batch. We were doing 100% incoming inspection. That defeats the purpose of having a supplier.”
A Fortune 500 manufacturer needed a reliable CNC partner for 40+ part numbers across aluminum, stainless steel, and brass. The previous relationship deteriorated as the supplier cut corners on quality control.
