Practical rules (general)
- Inside bend radius: as a starting point, equal to or larger than the material thickness in mild steel; we confirm per alloy.
- Minimum flange length: keep flanges long enough for the part to seat on the die; ask for the exact value by thickness.
- Holes near a bend: keep them farther than thickness plus radius, or they distort.
- Bend reliefs at corners to avoid tearing.
- Grain direction: bend perpendicular to the grain when possible, especially in aluminium.
These are reference rules; we confirm radii, angles and tolerances per part when quoting.
Our press-brake limits
- 3 m brake: carbon steel 1–6.35 mm; stainless 1–3 mm.
- 5.5 m brake: carbon steel 1–3 mm; stainless 2 mm.
- CNC bending with TRUMPF technology.
