Common Sheet Metal Design Mistakes That Increase Cost

Jun 20, 2026

In real production, we often see designs that are "manufacturable-but unnecessarily expensive."

In many cases, small adjustments in the design stage can save significant cost.

Here are 3 common issues:

1. Bend Flanges That Are Too Short
If the flange length is less than 2× the material thickness,
it becomes difficult-or even impossible-to form properly.

2. Holes Too Close to Bend Lines
Holes placed too close to bends can deform or crack during forming.
It's important to leave enough distance.

3. Unnecessary Tight Tolerances
Some dimensions don't affect assembly but are specified too strictly,
which directly increases manufacturing cost.

A good design is not just functional-it should also be easy to manufacture.

If you're unsure whether your design is production-friendly,
we can help review it early and avoid costly revisions later.
