The CCSi ASTM D624-A Specimen Cutting Die is engineered to produce the crescent-shaped tear specimens required for ASTM D624, Die A, used to measure tear propagation resistance in conventional vulcanized rubber and thermoplastic elastomers. This die is manufactured to standard (inch) dimensions; metric (mm) sizing is available on request.
Manufactured entirely in-house in Akron, Ohio, each die begins with premium American-made tool steel before undergoing precision grinding, machining, heat treating, wire EDM, sharpening, and final dimensional certification. Wire EDM manufacturing produces perfectly vertical cutting walls, allowing the die to be resharpened multiple times without affecting specimen dimensions for exceptional long-term value.
Die A cuts a crescent-shaped specimen that is nicked with a razor prior to testing; the applied force runs along the major axis, perpendicular to the nick, to measure how readily the tear propagates. This version does not include an integral nicker — nicking is done separately, either by hand with a razor or using CCSi’s specimen nicking apparatus.
If you’d rather have the nicking feature built into the die itself, see the ASTM D624-A (With Nicker) Specimen Cutting Die.
Every CCSi cutting die includes:
- Laser-engraved model and serial number for traceability
- Protective foam-lined carrying case
- Standard configuration for clicker-style presses
- Precision dimensional certification
Optional accessories include ISO-17025 Certification, Arbor Press Adapter, Mallet Handle, NAEF brackets and ejectors, and custom mounting solutions.
