Your part looks perfect in CAD. Then the quote comes back twice what you expected.
We see it constantly — parts designed for function, not for how they'll actually be made.
Before you send drawings to any fabricator, run through these 5 checks:
✅ Bend radius — inside radius should equal material thickness for air bending. Tighter radii = custom tooling, added cost, longer lead time.
✅ Fl**ge length — minimum is 5× material thickness. Shorter flanges mean inconsistent bends and higher per-part cost.
✅ Hole placement — holes within 5× material thickness of a bend line will distort. Those perfect circles in CAD come back oval.
✅ Dimensions — program OD (outside diameter) dimensions. Easier for operators to verify against the flat blank.
✅ Material callouts — "18 gauge" means something different for steel vs. aluminum. Be specific.
The best parts aren't fixed after quotes come back high. They're designed with fabrication in mind from the start.
