Die meisten Mehrkosten im Blech werden konstruiert, nicht gefertigt. Diese vier Regeln fangen die häufigsten ab.
1. Keep the inside bend radius equal to the material thickness. A radius smaller than the thickness needs a special punch, and on higher-strength steels it cracks the outer fibre. If your drawing says R0.5 on 2 mm steel, expect a question from us.
2. Keep holes at least 2.5× thickness away from the bend line. Closer than that and the hole deforms into an oval. If the hole must be close, we can pierce it after bending — but that is a second operation and a second setup.
3. Use the same bend radius everywhere on the part. Every different radius is a different tool change on the press brake, and setup time is real money on short runs.
4. Watch for a flange shorter than 4× thickness. It will not clear the die shoulder and cannot be formed on a standard V-die.
None of these are absolute — we bend parts that break every one of them. But each violation adds either a tool, an operation or a scrap risk, and it is much cheaper to know at the drawing stage than after the first article.
Ein Werkzeug kostet einmal Geld, Laserzeit kostet bei jedem Teil. So finden wir den Break-even an einem echten Bauteil.
