45 degree Press Brake Die is a lower bending die or die set with a 45° forming angle. It works together with an upper press brake punch to form acute bends, special profiles or pre-bending shapes in sheet metal.

This type of die is often used in:

• Acute angle bending

• Air bending

• Special sheet metal forming

• Cabinet and enclosure fabrication

• Metal panel production

• Custom press brake forming jobs

Compared with standard 90° press brake dies, a 45° die is more suitable for parts requiring sharper angles or special forming geometry.

Key Features

45° Acute Angle Design

The 45 degree forming angle supports sheet metal parts that require sharper bends than standard right-angle bending. It is suitable for customized fabrication and special profile forming.

Suitable for Air Bending

A 45 degree die can be used in air bending when the tooling, material thickness and press brake parameters are correctly matched. Air bending allows different final angles to be achieved by controlling punch depth and springback compensation.

Precision-Machined Die Profile

The die profile is processed with accurate angle control and dimensional consistency. This helps improve repeatability, reduce angle deviation and maintain stable bending quality.

Durable Tool Steel Material

The die can be produced from high-strength tool steel, alloy steel or customized material. Optional heat treatment improves wear resistance for long-term press brake operation.

Custom V-Opening Available

The V-opening can be designed according to sheet thickness, bend radius, material type and tonnage requirement. For air bending, the V-opening is one of the main factors that determines the natural inside bend radius.

Compatible with Different Press Brakes

Custom designs are available for CNC press brakes, hydraulic press brakes and mechanical press brakes. Tooling style can be adjusted to match European style, American style, WILA-style or other clamping systems.

Common Specifications

Applications of 45 Degree Press Brake Die

The 45 degree Press Brake Die is suitable for various sheet metal bending and forming applications, including:

• Stainless steel sheet bending

• Carbon steel plate bending

• Aluminum sheet forming

• Electrical cabinet manufacturing

• Metal enclosure production

• Machinery cover fabrication

• Door and panel bending

• HVAC sheet metal parts

• Automotive sheet metal components

• Elevator panel production

• Metal furniture parts

• Custom fabrication workshops

• Small-batch and mixed-order bending production

Why Choose a 45 Degree Press Brake Die?

A 45 degree die is useful when standard 90° dies cannot meet the required bending angle or forming shape. For manufacturers that process different sheet metal parts, it provides greater flexibility for acute angle forming and custom bending jobs.

Main advantages include:

• Better support for acute angle bending

• Suitable for customized sheet metal profiles

• Helps form sharp bends and special angles

• Can be used with air bending processes

• Supports custom V-opening and die length

• Available for different press brake tooling systems

• Helps improve bending consistency in repeat production

How to Choose the Right 45 Degree Press Brake Die

1. Confirm the Required Bend Angle

The die angle should be selected according to the target forming angle, bending method and springback. For acute angle bending, the punch and die must be properly matched to avoid angle error and material damage.

2. Select the Correct V-Opening

The V-opening affects the inside radius, required bending force, minimum flange length and surface marking. A larger V-opening usually creates a larger radius and lower forming pressure, while a smaller V-opening supports sharper bends but may require higher tonnage.

3. Check Sheet Metal Thickness

Different sheet thicknesses require different die openings and bending force. The die should be designed according to the actual thickness range used in production.

4. Consider Material Type

Carbon steel, stainless steel and aluminum behave differently during bending. Stainless steel normally requires more bending force, while aluminum may need careful radius control to reduce cracking.

5. Match the Press Brake Tooling Standard

Before ordering, confirm the press brake model, clamping system, die height, tang size and working length. This ensures the die can be installed and aligned correctly.

6. Choose Standard or Segmented Design

Full-length dies are suitable for long straight bending. Segmented 45 degree press brake dies are better for box bending, small parts and flexible production.
