CCSi manufactures these high quality Specimen Cutting Dies for the determination of fatigue life of rubber compounds undergoing a tensile—strain cycle, as described in ASTM D4482 ‘Standard Test Method for Rubber Property — Extension Cycling Fatigue’.
ASTM D4482 is also referred to as the “fatigue—to—failure” test, as a function of the popular instrument used to perform the test.
ASTM D4482 describes a procedure in which a test specimen is cyclically strained, at a fixed frequency, over a series of maximum extensions (flexing). The flexing causes cracks, usually initiated by a naturally occurring flaw, to grow and cause complete rupture of the test specimen (failure). The number of cycles required to cause failure is recorded as fatigue life.
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.
