Product Description

CCSi designs and manufactures high quality specimen cutting dies completely inhouse at our facility in Akron, OH. Our complete vertical integration allows CCSi to provide exceptional quality dies at competitive prices.

Our process starts with high, quality American made tool steel. We then grind, machine, harden, wire EDM, sharpen, and dimensionally certify the dies. The wire EDM manufacturing process creates perfectly vertical interior walls. This allows the die to be sharpened repeatedly without altering the dimensional characteristics of the sample and provides excellent long term value.

All CCSi dies come with the serial and model number laser engraved for easy identification. Also included is a rugged, foam lined carrying case for protection while the die is not in use.

Our standard dies have no adapters and are intended for use in a “clicker” style press.

CCSi manufactures these high quality UltraLife Specimen Cutting Dies for the comparison of the fatigue characteristics and rate of heat generation of rubber vulcanizates when subjected to dynamic compressive strains, as indicated in ASTM D623 ‘Standard Test Methods for Rubber Property – Heat Generation and Flexing Fatigue In Compression’.

ASTM D623 employs two distinct instruments, the Goodrich Flexometer in Test Method A and the Firestone Flexometer in Test Method B. The test specimens are also dramatically dissimilar. The Method A test specimen is prepared using a circular cutting die, although it is permissible to mold the specimen to the specific dimensions.

The Method A specimen is required to have a thickness of 25 ± 0.15 mm (1.0 ± 0.01 inch). This requires that a test piece be molded prior to cutting with the specimen die. CCSi manufactures laboratory quality molds for this purpose and for molding the specimen directly.

While most CCSi cutting dies are available with mallet handles, arbor press mounts, or press adapters, the Method A specimen cutting die is equipped with a special integral 0.375 inch diameter shaft. This facilitates mounting in a drill press, or similar device, as it is necessary to rotate the die while cutting the specimen.
