Manual Hydraulic Dumbbell Punch (Specimen Cutter)

Manual Hydraulic Dumbbell Punch: Effortless Sample Cutting

Preparing tensile test specimens from rubber or soft plastic sheets requires force and precision. If the sample edges are rough or nicked, the material will tear prematurely during testing, leading to false data. The Manual Hydraulic Dumbbell Punch is the ideal solution for laboratories that need to cut standard “dog-bone” shapes without the high cost of a pneumatic press.

Hydraulic Power for Clean Cuts

While mechanical lever presses struggle with thicker or harder rubbers (Shore A > 70), this machine uses a Manual Hydraulic System to generate significant cutting force with minimal operator effort. Key benefits include:

• High Cutting Force: Easily cuts through multi-layered rubber, leather, and semi-rigid plastics.
• Interchangeable Dies: The system accepts various cutting dies (knives) to produce different shapes, such as Dumbbells, Rectangles, or Crescents.
• Durability: Rugged construction suitable for harsh industrial environments, from small workshops to mass production quality control.

Versatility in Material Testing

This punch is essential for preparing samples for:

• Tensile Testing: Cutting ASTM D638 or ISO 37 Type 1/2/3 dumbbells.
• Tear Testing: Preparing “Trouser” or “Angle” tear specimens.
• Compression Set: Punching out standard discs.

The Next Step: Testing

Once your high-quality samples are cut, they are ready for mechanical characterization. This machine is the perfect companion to our Universal Testing Machine (UTM), ensuring your test results are based on perfectly dimensioned specimens.

International Standards Compliance

Depending on the cutting die installed, this machine prepares samples compliant with:

• ISO 37: Rubber, vulcanized or thermoplastic — Determination of tensile stress-strain properties.
• ASTM D638: Standard Test Method for Tensile Properties of Plastics.
• ISO 527 and ASTM D412.
