What Is a 30 Degree Press Brake Die?

A 30 degree Press Brake Die is a lower press brake tool with a 30° V groove or acute angle forming profile. It works together with an upper punch to bend sheet metal into sharp angles or prepare parts for secondary forming.

In press brake bending, the die angle does not always have to match the final bend angle. For air bending, the punch angle and die angle only need to be smaller than the desired final angle after considering springback. This is why a 30 degree die can be used for more than one bending angle when properly selected.

Key Features

Acute Angle Forming

The 30° die profile is suitable for acute angle bending and sharp sheet metal forming. It is commonly used when the required bend angle is smaller than a standard right-angle bend.

Suitable for Hemming Preparation

A 30 degree press brake die is often used for the first bending step before hemming. The sheet metal is first bent to an acute angle and then flattened in a second operation to form a hemmed edge.

Air Bending Flexibility

With the correct punch, V-opening and machine control, a 30 degree die can be used for different bending angles through air forming. This makes it useful for workshops that need flexible forming capability.

Precision-Machined V Groove

The die groove is machined with controlled angle accuracy and surface finish to support stable bending results, reduce deformation and improve repeatability during sheet metal forming.

Durable Tool Steel Material

The die can be made from high-strength tool steel, alloy steel or customized material according to production load. Optional heat treatment can improve wear resistance and tool life.

Custom Design Available

Custom die length, V-opening size, working height, angle, segmentation and clamping style can be produced according to your press brake model and bending requirements.

Common Specifications

Applications

The 30 degree Press Brake Die is suitable for many sheet metal fabrication applications, including:

• Acute angle sheet metal bending

• Hemming pre-bending

• Stainless steel bending

• Carbon steel forming

• Aluminum sheet bending

• Electrical cabinet manufacturing

• Metal enclosure production

• Door and panel forming

• HVAC sheet metal parts

• Automotive sheet metal components

• Machinery covers and guards

• General press brake fabrication

Why Use a 30 Degree Press Brake Die?

A 30 degree die gives fabricators more forming flexibility than a standard 90 degree die when working with acute angles or hemming operations. It is especially useful when parts require a sharp bend, a pre-bend before flattening, or controlled springback compensation.

For sheet metal workshops, the main benefits include:

• Better support for acute angle bending

• Suitable for hemming preparation

• Flexible air bending capability

• Reduced need for special one-purpose tooling

• Stable forming accuracy with proper setup

• Custom options for different press brake systems

How to Choose the Right 30 Degree Press Brake Die

1. Confirm Sheet Thickness

The V-opening should be selected according to the material thickness. A larger V-opening generally produces a larger inside radius and requires lower bending force, while a smaller V-opening creates a sharper bend but may increase tonnage requirements. The V-opening has a major effect on bend radius, bending force, minimum leg length and surface marking.

2. Check Material Type

Carbon steel, stainless steel and aluminum have different forming behavior. Stainless steel usually needs higher bending force, while aluminum may require careful tooling selection to reduce cracking and surface damage.

3. Match the Press Brake Tooling System

The die must match the press brake table, clamping system and tooling standard. Common options include European style, American style, WILA style and custom press brake tooling systems.

4. Consider the Bending Process

If the die is used for hemming preparation, the die angle, punch tip, V-opening and flattening tool should be planned together.

5. Choose the Correct Die Length

Full-length dies are suitable for long bending parts, while segmented 30 degree press brake dies are better for box bending, small parts and flexible production.

6. Confirm Hardness and Surface Treatment

For high-volume production, hardened working surfaces can improve wear resistance and extend service life.
