- MIL-A-8625 Type III anodize process cert
What Madison Defense Buyers Should Know
UW-Madison defense research prototypes need fast iteration
DARPA and Army Research Lab funded programs at UW move quickly. Your machining partner needs 3-5 day prototype capability.
Oshkosh Defense programs drive regional machining demand
When JLTV or FMTV production accelerates, Wisconsin machining capacity tightens. Have a backup supplier with fixed lead times.
ITAR registration is required even for university defense work
DoD-funded research programs handle controlled technical data. Your supplier must be pursuing ITAR registration regardless of the customer type.
When Your Local Shop Can't Keep Up
When a prime contract surges volume, smaller buyers get pushed back. We give you fixed lead times, ITAR compliance, and mil-spec documentation — every time. Madison's defense sector demands it.
