High-Precision Custom Press Brake Tooling & Dies

Custom Press Brake Tooling FAQ

Q1: Which press brake brands fit your customized tools?

Q2: What raw materials and hardness grades are available for custom molds?

We mainly adopt premium 42CrMo4 alloy steel. Other alloy grades are available for heavy wear working scenarios, you can contact our team to get tailored material solutions. All products go through full-length induction quenching and tempering treatment, with hardness kept between 45 to 50 HRC, stable in accuracy and anti-deformation performance for long service use.

Q3: Is customized tool design available for irregular bending shapes?

Yes. Our technical team designs special goose neck punches, sharp angle tools and multi-V molds according to your product sketches when standard tools fail to meet processing demands. 2D and 3D design drawings will be submitted for your confirmation before formal production.

Q4: How to guarantee stable bending angle accuracy?

Key working surfaces of every tool are finely polished strictly. Height and V groove size follow tight tolerance control, keeping unified bending angle effect along the whole equipment working range.

Q5: How long does it take to finish customized press brake tools?

Production cycle ranges from 15 to 25 days, decided by product complexity. Rush order service is accessible for sample making. Finished goods will be coated with anti-rust oil and packed in solid wooden cases to meet international shipping requirements.

Q6: What regular segmented sizes apply to European standard bending tools?

Common European standard segmented specifications:835mm combined set (10 pieces): 10mm, 15mm, 20mm, 40mm, 50mm, 100mm, left 100mm, right 100mm, 200mm, 300mm 415mm combined set: 10mm, 15mm, 20mm, 40mm, 50mm, 100mm, 180mm

Custom Press Brake Tooling: For Complex Bending

Tailored Custom Solutions

• Every project has unique challenges (e.g., tight radii, deep box bending).

• We use advanced CAD/CAM technology to make tooling that fits your machine perfectly.

• This reduces setup time and ensures smooth use.

Core Parts & How It Works

Upper Die

• Installed on the machine’s moving slider (applies pressure).

• Its shape (straight, sharp, gooseneck, arc) decides the workpiece’s outer shape.

Lower Die

• Fixed on the machine’s workbench (supports the workpiece).

• It usually has a V-shaped groove.

• Groove width affects bending force, fillet size, and forming effect.

Working Principle

1. Place the metal sheet on the lower die.

2. The slider drives the upper die down to press the sheet.

3. The sheet bends to match the dies (permanent shape change).

4. After reaching the set pressure/stroke, the upper die moves back.

5. Take out the finished workpiece.

Key Features of Press Brake Tooling

• Strong & Wear-Resistant: Made of alloy steel (e.g., 42CrMo). Heat-treated to be hard (HRC45-HRC50) and durable.

• Customizable: Make punches/dies in special shapes (arc, gooseneck) or V-grooves (8mm, 16mm, 24mm) for your needs.

• Good Compatibility: Tooling fits your machine and workpiece perfectly (size, shape, requirements).

• Standard Options: Conventional tooling fits common machines (Amada, Trumpf, Wille). Special tooling can be customized.

Common Types of Press Brake Tooling

By Forming Shape

• Standard Straight Edge: For regular straight bending (most common).

• Sharp Angle: For small angles or springback correction (high precision).

• Gooseneck: For U-shaped/deep channel workpieces (avoids interference).

• Arc: For curved or rounded workpieces.

• Irregular: Custom-made for special workpiece drawings.

By Application

• Standard Sheet Metal: For mild steel, galvanized steel (cost-effective).

• High-Strength Steel: Thick, hard material for stainless steel/alloy plates.

• Thin Material: Precision-made to prevent warping, damage, or scratches.

By Installation Interface

• Amada/Promecam: Fits Amada machines.

• Trumpf/Wila: Fits Trumpf and Wila machines.

• New Standard: Universal (fits most domestic machines).

How to Choose Press Brake Tooling

1. Match Material Characteristics

• Different metals have different springback (mild steel = little springback; stainless steel = more springback).

• Use the right punch angle to fix springback (e.g., 86°~88° for mild steel; 85° for stainless steel).

• Tooling material: 42CrMo (hardness HRC45-HRC50, strong and tough).

2. Follow the "8x Principle" (Lower Die V-Groove Width)

• Core rule: V (groove width) = 8 × T (material thickness) – best for 3-8mm plates.

• Adjust for thin plates (T＜3mm): V=6T (smaller fillet).

• Adjust for thick plates (T＞8mm): V=10T~12T (reduces bending force).

3. Check Pressure Tonnage

• Tooling must handle the machine’s pressure (no overloading – it breaks tooling/machines).

• Calculate pressure using material thickness, tensile strength, and V-groove width.

• Machine tonnage must be 10%-15% less than tooling’s maximum capacity.

4. Choose the Right Punch Shape

• Standard punch: Regular straight bending.

• Sharp punch: Small angles or springback correction.

• Gooseneck punch: U-shaped/deep channel workpieces (avoids interference).

• Custom punches: For circular/irregular workpieces (match drawings).

5. Ensure Machine Compatibility

• Punch shank must fit the machine’s clamping system (Amada, Trumpf, etc.).

• Tooling height must match the machine’s slider stroke and worktable height.

Important Notes

• Don’t ignore springback (causes wrong angles).

• Follow the "8x rule" (prevents workpiece cracking and tooling damage).

• Check machine compatibility (prevents installation failure).
