Herausforderung · The bracket had moved to a second supplier after the first die began producing burred pierced holes; rework had climbed to roughly 12% of each lot and the customer was paying for hand deburring on every shipment.
Unsere Änderung · We rebuilt the progressive die in our own tool room — 11 stations, revised punch-to-die clearance for the 2.0 mm SPCC, and a countersink station added inside the die so the chamfer no longer needed a second operation.
Ergebnis · Burr-related rework fell to 0.4% over the first three months of production. Removing the off-line deburring step cut piece cost by about 18% while tightening the pierced-hole tolerance to ±0.05 mm, and every release now ships with a first-article inspection report.
