Overview
30 Degree Press Brake Die Capabilities & Versatility
Precision Sheet Metal Bending
Our 30 degree forming press brake die provides the deep relief required for acute angle forming, return bends, and tight-clearance geometries. By maximizing space around the punch tip, this tooling eliminates workpiece collision issues common with standard 88° or 90° dies.
Air Bending Versatility: 30° Acute Folds to 90° Bends
Through air bending, a single 30-degree acute die handles a broad spectrum of bend angles without swapping lower tooling:
30° Acute Bends: Produces sharp, high-precision acute angles in standard and high-tensile sheet metal.
45° to 60° Intermediate Angles: Enables controlled over-bending to offset aggressive material springback.
90° Universal Bends: Forms precise 90-degree right angles, significantly cutting down machine setup time and tool inventory requirements.
Stage-One Pre-Hemming Integration
Our acute tooling works seamlessly as a stage-one pre-hemming tool for two-step hem creation:
1. Pre-Bend (Stage 1): The 30° acute die creates an initial tight pre-fold in the sheet metal edge.
2. Flattening (Stage 2): A dedicated flattening die or combination hemmer closes the fold to form a smooth, secure seam.
Precision Surface Grinding & Tolerances
- Profile Accuracy: Precision CNC ground to tight ±0.01 mm profile tolerances along the full tool length.
- Consistency: Delivers flawless angle accuracy and uniform flange heights across long production runs.
- Surface Quality: Smoothly finished V-groove working radii minimize friction and prevent surface galling on sensitive sheet materials.

Technical FAQs for 30 Degree Press Brake Dies
How to Select the Proper V-Opening for a 30 Degree Acute Die?
Selecting the correct V-opening for a 30 degree press brake die requires accounting for deeper punch penetration during acute air bending. While standard 90° air bending typically uses an 8x sheet thickness rule, 30° acute bending demands a wider V-opening to accommodate punch clearance and prevent sheet binding against the die shoulders.
| Material Thickness | Recommended V-Opening | Minimum Flange Length |
|---|---|---|
| 0.8 mm – 1.2 mm | 8 mm – 10 mm | 5.5 mm |
| 1.5 mm – 2.0 mm | 12 mm – 16 mm | 9.0 mm |
| 2.5 mm – 3.0 mm | 20 mm – 25 mm | 14.0 mm |
| 4.0 mm – 6.0 mm | 32 mm – 50 mm | 28.0 mm |
For high-tensile materials with significant springback, we recommend stepping up to the next wider V-opening to reduce required bending tonnage and safeguard working edges.
Can a 30-Degree Press Brake Die Form Standard 90-Degree Bends?
Yes. In air bending operations, a 30 degree forming press brake die offers exceptional process flexibility. Because the sheet metal only makes contact with the two ground shoulder radii of the die, you can air bend any angle from 30° up to 179°, including standard 90° bends.
However, bottoming or coining a 90° bend inside a 30° acute die profile is not possible. If your production line transitions directly from acute pre-bending to flattened seams, explore our specialized hemming dies to streamline your two-stage bending process.
How Is Die Accuracy Guaranteed Over Long Tool Lengths?
We ensure precise linear accuracy across full-length rails and sectional sets through strict CNC manufacturing protocols:
- Precision Surface Grinding: Critical working edges and seating bases are CNC precision ground to profile tolerances within ±0.01 mm per meter.
- Matched Sectional Sets: Standard segmented sets (such as 835 mm or 415 mm split tooling) undergo matched-set grinding to guarantee seamless height alignment across extended bed lengths.
- 100% CMM Verification: Every tool undergoes Coordinate Measuring Machine (CMM) dimensional checks and laser profile inspection prior to shipment.
- Dual-Zone Heat Treatment: High-grade 42CrMo alloy steel cores (47–50 HRC) are paired with deep induction hardened working zones (55–60 HRC) to stop long-term wear and angular deviation.
What Is the Lead Time for Standard vs. Custom Segmented 30° Dies?
Lead times depend on profile complexity, clamping configuration, and stock availability:
| Tooling Type | Standard Stocked Specifications | Average Lead Time |
|---|---|---|
| Standard Stock Sets | 835 mm, 415 mm, or pre-segmented sets (Amada, Promecam, Wila styles) | Ships within 24 to 48 hours |
| Custom V-Width / Height | Custom V-openings, altered heights, or ground shoulder radii | 10 to 15 business days |
| Engineered Custom Sets | Specialized sectional cuts, non-marking urethane pockets, heavy-duty geometries | 15 to 20 business days |
Our technical team provides 2D DXF/DWG layouts and 3D STEP models within 24 hours for custom orders, allowing virtual press brake collision verification before machining begins.
