Specimen Die - ASTM D1708 Micro Sample Cutting Die for Tensile Testing of Plastic Materials

Precision Sample Preparation for Micro-Tensile Testing

The ASTM D1708 Sample Cutting Die is engineered for the precise preparation of micro-tensile specimens used in the testing of plastics. Manufactured using state-of-the-art CNC and Wire EDM (Electrical Discharge Machining) technology, this die ensures defect-free edges—critical for accurate tensile data.

Hardened to 56 Rockwell C, this tool is designed for high-volume industrial applications where durability and edge retention are paramount. Each die comes with an Inspection Certificate (valid for 1 year) and is housed in a rugged protective case.

Ideal Applications

Key Features & Advantages

• ✔
  Superior Durability: Hardened tool steel (56 HRC) resists dulling, extending the lifespan of the die even when cutting abrasive plastics.
• ✔
  Wire EDM Precision: Unlike stamped dies which can leave micro-fractures on the sample edge, Wire EDM ensures a perfectly smooth cut, preventing premature failure during tensile tests.
• ✔
  Certified Accuracy: Every die includes a detailed Inspection Certificate verifying dimensions against the standard.
• ✔
  Protective Packaging: Shipped in a hard plastic case with custom foam padding to prevent damage during storage or transit.

Technical Specifications

🔧 Re-Sharpening & Maintenance Service

To maintain ISO/ASTM compliance, we recommend annual re-sharpening. Dull dies can introduce stress concentrations in samples, skewing tensile results.

• • Track Your Maintenance: The re-sharpen due date is clearly marked on the carrying case label.
• • Easy Process: Contact us to receive a case number. We will inspect, sharpen, and re-certify your die to factory specs.
