Practical Applications and User Guide for CHAOERO Multi V Die

What Is a Multi V Die?

A Multi V Dieis a type of press brake lower die that integrates multiple V-shaped openings in one tool body.

The operator can simply rotate the die body to select the proper V width without changing the die.

This flexible design greatly reduces setup time and improves bending efficiency for multi-size production.

A typical multi V die includes 4–6 different V openings, such as V8 / V12 / V16 / V20 / V25 / V32, suitable for different plate thicknesses or bending radii.

CHAOERO Multi V Diescan be customized in length (3m, 4m, or 6m)and segmented to match various press brake setups.

CHAOERO Multi V Die’s Advantages

In traditional bending, every sheet thickness requires a different die, which takes time and interrupts continuous production.

CHAOERO Multi V Dieallows fast switching between V openings by rotation, without disassembly.

Main Advantages

1. Shorter Setup Time and Higher Efficiency

• One die for multiple uses:A single multi V die includes several V openings (e.g., V8, V10, V12, V16).
  Operators can switch to the proper opening by sliding or rotating the die—no frequent die changes needed, saving time and increasing productivity.
• Fewer setups for complex parts:For multi-bend components, the multi-slot design reduces tool changes and simplifies the bending process.

2. Lower Overall Cost

• Reduced investment:Buying one multi V die costs far less than purchasing several single V dies.
• Less storage and space:One die replaces many, saving warehouse space and simplifying tool management.

3. Wide Material Compatibility
A single die can handle sheet thicknesses from 1mm to 10mm, suitable for stainless steel, aluminum, and carbon steel.

4. Improved Machine Utilization and Flexibility
Multi V Dies enable quick response to multi-size, small-batch production, providing greater flexibility for diverse customer needs.

CHAOERO Multi V Die – Application Cases

Case 1: General Sheet Metal Fabrication Factory (Saudi Arabia)

Customer Issue:
Each time a different thickness part was processed, the operator had to stop, remove the old die, install a new one, and realign the setup.
This took a long time, required many different single V dies, and caused high tooling costs. The factory could not react quickly to urgent sample changes, losing orders due to low flexibility.

CHAOERO Solution:
Adopted a CHAOERO Multi V Die.

Results:

• Die change time reduced from 30 minutes to under 5 minutes.
• Improved bending accuracy and repeatability.
• One die covered all thickness requirements, improving efficiency and market competitiveness.

Case 2: Elevator Decoration Panel Factory (Brazil)

Customer Issue:
Elevator interior panels use stainless steel or pre-coated sheetsthat must remain flawless after bending—no marks or scratches allowed.
Shapes are complex and vary in bend angle and size.

CHAOERO Solution:
Used a CHAOERO Multi V Diewith R-radius groovesand polished surfacesto protect the material finish.

Results:

• Completely eliminated surface marks.
• Reduced scrap rate and ensured premium appearance.
• One die supported multiple bending requirements.

Case 3: Construction Machinery Parts Manufacturer (India)

Customer Issue:
Producing cabin brackets and support frames using 8mm–12mm carbon steel platesrequired durable dies and high stability.
Frequent die changes were inefficient and unsafe due to the heavy weight of single V dies.

CHAOERO Solution:
Implemented a CHAOERO Heavy-Duty Multi V Die (V30/40/50 three-slot model).

Results:

• Extended die life and maintained accuracy.
• Reduced replacement costs and improved operator safety.
• Ensured continuous, efficient thick-plate bending.

How to Use CHAOERO Multi V Die

1. Identify the V Opening– Each slot is labeled (e.g., V12, V20).
2. Rotate the Die– Loosen the clamping system and rotate to the required opening.
3. Lock Position– Secure using alignment pins or quick clamps.
4. Adjust Parameters– Reset bending stroke and tonnage according to V width.
5. Test Bend– Verify sample accuracy before mass production.

Tip:For standard bending, choose the V opening by the formula V = 6t to 10t(t = sheet thickness).
