TRUMPF Type Size I RE25×4 Rectangular Punch & Die Tooling

The TRUMPF Type Size I RE25×4 Rectangular Punch & Die Tooling is designed for precision rectangular hole and profile punching in sheet metal fabrication applications using TRUMPF-style Size I tooling systems.

The tooling shown on this page is an RE25×4 rectangular punch and die set manufactured as a representative sample of our TRUMPF Type punching tooling capability. In this designation, RE represents a rectangular punching profile, while 25 × 4 mm identifies the nominal length and width of the punched feature.

Both punch and corresponding lower dies are shown in the product images, demonstrating a complete tooling solution for rectangular sheet metal punching.

The RE25×4 specification is a sample rather than a fixed limitation. Different rectangular dimensions, die clearances and special punching geometries can be manufactured according to customer drawings and actual sheet metal processing requirements.

Technical Specifications

What Does RE25×4 Mean?

RE25×4 identifies the shape and nominal dimensions of this punching tool.

RE refers to a rectangular profile, while 25 × 4 mm represents a rectangle approximately 25 mm long and 4 mm wide.

The RE25×4 configuration shown here is intended to demonstrate our manufacturing capability for narrow rectangular punching profiles.

Other rectangular dimensions and length-to-width ratios can be manufactured according to the required hole geometry.

Rectangular Punch & Die for Sheet Metal

Rectangular punch tooling is commonly used when a component requires a straight-sided opening rather than a round or obround hole.

During punching, the rectangular punch and lower die work together as a matched tooling system. The punch passes through the sheet material toward the die opening, shearing the material along the rectangular cutting profile.

Accurate punch geometry and appropriate die clearance are therefore important factors in achieving consistent punching results.

Our RE25×4 tooling can be supplied as the required punch, lower die or corresponding punch-and-die tooling according to the customer's application.

Custom Lower Die Clearance

For the same RE25×4 punching profile, the required lower die specification may vary depending on the sheet material and thickness.

The die clearance can therefore be customized according to the actual punching application.

When ordering, customers can provide:

• Sheet material
• Material thickness
• Required hole dimensions
• Required punching profile
• Existing tooling information
• Workpiece drawing

These parameters can be used to determine an appropriate punch and die configuration.

Custom Rectangular Punching Sizes

The 25 × 4 mm rectangular profile is only the sample specification shown on this page.

We can manufacture other rectangular punching dimensions according to customer requirements. This allows the tooling to be matched to mounting slots, ventilation openings, assembly features and other rectangular features incorporated into sheet metal components.

Customers requiring a non-standard rectangular profile can provide the required length and width directly or send us the component drawing.

Standard & Special Punching Profiles

Our TRUMPF Type punching tooling capability extends beyond rectangular profiles.

Common punching shapes include:

• RO – Round
• SQ – Square
• RE – Rectangle
• OB – Obround / Oblong
• Slot profiles
• Polygonal profiles
• Keyhole-type profiles
• Notching profiles
• Irregular contours
• Special-shaped punching profiles

For complex components, custom punch and die tooling can be manufactured according to DXF, CAD or finished-part drawings.

This makes it possible to produce tooling not only for standard holes but also for application-specific sheet metal features.

Typical Applications

TRUMPF Type Size I rectangular punch tooling can be used for manufacturing components such as:

• Electrical cabinets
• Switchgear panels
• Control panels
• Sheet metal enclosures
• Machinery covers and guards
• Equipment housings
• HVAC sheet metal components
• Mounting plates
• Metal brackets
• Industrial equipment panels
• Automotive sheet metal components
• Custom fabricated metal parts

The narrow RE25×4 rectangular profile can be particularly useful for components requiring rectangular slots, mounting openings or other straight-sided punched features.

Custom TRUMPF Punch Tooling from Your Drawing

The RE25×4 tooling displayed on this page is one example of our custom TRUMPF Type punch tooling manufacturing capability.

Customers are not limited to the dimensions or shape shown.

For a customized punching application, simply provide the required profile and dimensions or send us the DXF, CAD or finished sheet metal part drawing, together with the material and sheet thickness.

Based on these requirements, we can manufacture the corresponding punch and lower die with the required shape, dimensions and die clearance.

From standard round, square, rectangular and obround tooling to complex special profiles, customized punching tools are available for different sheet metal fabrication requirements.
