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 Specimen Cutting Dies for determining the cracking resistance of vulcanized rubber exposed under dynamic strain conditions to a chamber atmosphere containing ozone at a fixed partial pressure, as described in D1149 ‘Standard Test Methods for Rubber Deterioration—Cracking in an Ozone Controlled Environment’. The effects of sun or ultraviolet light are excluded.

ASTM D1149 Method B describes four procedures, Method B1 (exposure of straight specimens),  Method B2 (exposure of bent loop specimens), Method B3 (exposure of tapered specimens), and Method B4 (expoure of triangular specimens). Methods B1-B3 use die-cut samples; Method B4 uses a molded sample.

The method B3 die is 25 x 137 x 6mm radius (1.5 x 5 x 0.25 radius)

These determine, in a comparative sense, the degree of ozone resistance of a material under the accelerated conditions of the tests.

CCSi provides the OREC™ Ozone Chamber, which is suitable for performing the Dynamic Ozone Test, as well as molds and cutting dies used in other ozone test procedures.
