Managing four or five vendors across a single stamped assembly is a coordination problem that compounds with every revision cycle. Tolerances set in one shop get interpreted differently in the next, and by the time a fit issue surfaces, the paper trail is already a mess.
D&H Industries runs progressive die stamping, deep draw, welding, CNC machining, hardware insertion, and complete assembly under two roofs in Oconomowoc, WI (dhmetalstamping.com). That means a single revision gets applied once, not cascaded across a supplier network hoping everyone gets the memo.
ISO 9001:2015 certification covers both facilities, so the quality documentation that procurement needs for approved supplier lists is already in place. Press capacity runs from 100 to 2,000 tons across aluminum, stainless, cold-rolled steel, and high-strength materials, which covers a wide range of part geometries without splitting the work.
How many vendors are you currently managing across a single part family, and has consolidation ever come up as a real option or does it stay a whiteboard conversation?
