ASTM D623 Specimen Cutting Die
UltraLife D623 Method A Die
UltraLife Cutting Dies by CCSi
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 D623Standard 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 (shown on the left), 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.
The Method B specimen is shaped as the ‘frustrum of a rectangular pyramid’ and therefore requires that it be molded (see below), for control purposes. CCSi manufactures molds for this application as well. Tests may also be conducted on specimens prepared from finished articles, requiring that they be roughly cut, then finished to the required dimensions by buffing or grinding.
CCSi features the Emerson Type Rubber Buffer and the Hung Ta™ Par-Marton Type Specimen Adjuster, both of which are suitable for this application and comply with the requirements of ASTM D3183Standard Practice for Rubber — Preparation of Pieces for Test Purposes from Products’.
CCSi UltraLife Specimen Dies: Quality Manufacturing
CCSi UltraLife specimen cutting dies are manufactured from homogenous, solid, high carbon content A2 tool steel. Each undergoes multi-axis precision grinding and conventional, plunge, or wire EDM (Electrical Discharge Machining) processes ... producing a world-class, close tolerance die.
Precision grinding and EDM processes ensure true parallelism and multi-plane dimensional accuracy. The quality of materials, design, and engineering serve to provide the highest specimen quality possible, over an extended service life.
Where highly technical manufacturing techniques and processes end ... old-world craftsmanship begins!
CCSi UltraLife specimen cutting dies are individually serialized, hand-honed, and mirror polished. A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection.
Each UltraLife specimen cutting die includes a detailed final report and certification to the applicable standard, traceable to NIST, and compliant with ISO 9001:2000 and ISO/IEC 17025. The specimen dies are placed in a plastic, blow-molded, ‘clam shell’ style case with a foam lining to protect the die during transport and storage.
