Built for Precision Bending Performance
Our sheet metal bending tooling combines high core toughness with hard wear zones to maximize tool life under continuous production:
- Induction-Hardened Working Edges: Deep induction hardening on high-wear radii prevents structural fatigue while maintaining core ductility.
- Tight Tolerances: Precision grinding eliminates angular variation across long sheet sections or segmented tooling setups.
- Low-Friction Surface Finish: An ultra-smooth Ra < 0.8 µm finish minimizes surface friction, protecting sensitive alloys and reducing galling. For specialized tool geometry requirements, we design fully tailored custom press brake tooling built to your exact forming specifications.

CAMT Custom Engineering & 3D Bending Simulation Workflow

CAD Submission & Analysis
Submit your 2D files (DXF/DWG) or 3D models (STEP/IGES). We evaluate part geometry, bend sequence, flange heights, and sheet thickness to determine the exact punch and die setup needed for your sheet metal bending tooling.
3D Bending Simulation
We run full press-stroke 3D simulations to identify potential interference between the sheet metal, ram, and bed. This digital modeling verifies clearance for deep channel profiles, narrow return flanges, and complex offsets prior to manufacturing.
Tonnage & Springback Calculation
Our engineering team calculates exact bending force requirements based on material tensile strength, yield, and sheet thickness. We build springback compensation directly into the tool geometry to hit target bend angles consistently. To review material selection limits and structural properties, refer to our press brake tooling material guide.
Precision CNC Tooling Fabrication
Each CNC precision ground press brake die is manufactured from certified alloy tool steel through multi-axis CNC milling, vacuum heat treatment, and deep induction edge hardening. grinding achieves ultra-tight tolerances and smooth contact surfaces.
CMM Quality Inspection
Every finished die section undergoes comprehensive quality testing before packaging:
- Dimensional Precision: Verified across full tool length to ±0.01 mm using CMM optical measurement.
- Hardness Profile: Induction-hardened working edges rated at HRC 55–60, with a shock-absorbing core at HRC 28–32.
- Surface Polish: Roughness profiling ensures an Ra < 0.8 µm finish to eliminate friction drag and surface marking on bent parts.
Frequently Asked Questions (Technical FAQ)
What is the advantage of a multi bend press brake die over standard single-V dies?
A multi bend press brake die allows operators to process multiple material thicknesses or perform progressive channel bends in a single machine setup. Unlike standard single-V dies that require constant tooling swaps, a 10-way multi-V die block or custom multi-stage profile minimizes machine downtime, speeds up production cycles, and easily accommodates complex, narrow-return flanges.
How do I select the correct V-opening for a multi-V bending die?
Selecting the correct V-opening depends on material thickness (t), yield strength, and the required inner bend radius. We generally recommend applying the 8x t rule for air bending mild steel:
| Material Thickness (t) | Recommended V-Opening (V) | Typical Application Scenarios |
|---|---|---|
| 0.5 – 1.2 mm | 6 mm – 8 mm | Thin-gauge HVAC ducting, light chassis |
| 1.5 – 2.5 mm | 12 mm – 16 mm | Electrical enclosures, switchgear cabinets |
| 3.0 – 4.0 mm | 22 mm – 32 mm | Heavy metal furniture, structural channels |
| 5.0 mm and above | 8x t to 10x t | Infrastructure components, thick plate |
For specialized profiles or acute angles, review our full range of press brake V-dies to match your machine tonnage and springback parameters.
Can CAMT customize multi-bend tooling for specific press brake clamping systems?
Yes. We manufacture and precision-grind custom multi-bend tooling to match any press brake clamping system on the market:
- WILA / Trumpf / New Standard: Self-seating pin and button-clamping systems

- American Standard: Conventional press brake tang geometries
- Brand Compatibility: Direct fit for Amada, Bystronic, LVD, Cincinnati, and Durma machinery
How does CAMT prevent sheet metal scratching during multi-bend operations?
We protect sensitive materials like stainless steel, aluminum, and pre-painted sheet metal through three main features:
- Ultra-Smooth Surface Finish: CNC precision grinding achieves a surface roughness of Ra < 0.8 µm, drastically lowering friction drag.
- Deep Induction Hardening: Edge hardness reaching HRC 55–60 prevents galling and material pickup on the die shoulders.
- Non-Marking Accessories: Compatible geometry designed to work seamlessly with protective polyurethane die film.
