Typical Applications

This 85° R0.25 high press brake upper punch is designed for workpieces that require higher closed-profile, semi-closed, or deep bending geometries.

Typical applications include:

• High closed-profile bending
• Deep closed-section bending
• Semi-closed profile bending
• Thin sheet metal bending
• Precision sheet metal forming
• Narrow opening components
• Deep channels and box-shaped parts
• Electrical cabinets and enclosures
• Machinery components
• Precision brackets
• Metal housings
• Complex sheet metal profiles
• Multi-step bending operations

The 150 mm overall height provides a longer working reach than standard 97 mm or 120 mm upper punches. This makes the tooling particularly suitable when the workpiece has a higher closed profile or deeper formed section and a conventional-height punch may not provide sufficient access.

The R0.25 small radius allows the punch to form a relatively small inside bend radius, making it useful for applications where a compact bend radius is required.

The 9 mm load-bearing section provides a balance between tooling strength and accessibility. It is suitable for closed-profile applications where some clearance is required while maintaining an 80 ton/m load capacity.

For thin sheet metal, the small R0.25 radius can also be advantageous for precision forming. Actual bending results will depend on material type, sheet thickness, bending length, die opening, bending method, and machine parameters.

This tooling can be manufactured for applications involving major press brake brands and tooling systems, including Amada, TRUMPF, LVD, Bystronic, and WILA, according to the specific machine interface and tooling requirements.

Product Details & Manufacturing Quality

The punch is manufactured from 42CrMo alloy steel, providing high strength, toughness, wear resistance, and durability for repeated press brake operations.

The working section is heat treated to approximately HRC 54 ± 2, helping maintain dimensional stability and wear resistance during continuous production.

The main design feature is the combination of a 150 mm high tooling profile and R0.25 small tip radius.

Compared with conventional R1 punches, the R0.25 configuration can produce a smaller forming radius, making it suitable for applications where the workpiece requires a more compact bend geometry.

The 150 mm overall height is particularly important for this product. It allows the tooling to reach and form higher closed profiles where standard-height upper punches may have insufficient working reach.

The 9 mm load-bearing section provides a practical balance between accessibility and strength, while the 80 ton/m load capacity makes it suitable for a broad range of medium-duty industrial bending applications.

Actual allowable bending force should always be evaluated according to the workpiece material, thickness, bending length, die opening, bending method, and press brake specifications.

Standard & Custom Press Brake Tooling

We manufacture standard press brake tooling and customized punches and dies for different bending machines and workpiece requirements.

For customers producing higher closed-profile or deep-formed components, selecting the correct punch height is especially important. A standard 97 mm or 120 mm punch may not always provide sufficient reach or clearance.

If you have a workpiece requiring a high closed bend, you can send us your 2D/3D drawing, bending drawing, sample, or machine specifications.

Our engineering team can provide a free press brake tooling design service and recommend the appropriate punch and die configuration.

Customization options include:

• Overall tooling height
• Total tooling width
• Load-bearing section width
• Tip width
• Tip radius
• Punch angle
• Tooling length
• Clearance and relief areas
• Closed-profile bending structures
• Gooseneck punches
• Special-shaped punches
• Machine-specific tooling dimensions
• Customized upper and lower tooling sets

We can also evaluate closed-profile clearance, bending sequence, tool interference, flange geometry, bend radius, and required bending force before production.

This allows us to provide a complete custom press brake tooling solution for high closed-profile and complex sheet metal bending.
