CCSi UltraLife Specimen Cutting Dies: ASTM D1646 |
D1646 Upper Specimen Die

|
CCSi manufactures these high quality Specimen Cutting Dies for the techniques employed to measure certain properties using a Mooney Viscometer, as described in ASTM D1646 ‘Standard Test Methods for Rubber — Viscosity, Stress Relaxation, and Pre-Vulcanization Characteristics (Mooney Viscometer)’:
- Mooney viscosity, the shearing torque resisting the rotation of a rotor, embedded in rubber, within a die cavity;
- stress relaxation, upon abruptly stopping the rotation of the rotor, the torque or stress, on the rotor decreases at a rate dependent on the rubber and the temperature of the test;
- pre-vulcanization, when compounded rubber is tested at a temperature at which vulcanization may occur, the vulcanization reaction produces an increase in torque.
|
| It is necessary for the Mooney Viscometer test specimens to be formed in two halves, as they act as an envelope in which the rotor is encapsulated. The lower specimen half requires a centrally located orifice through which the shaft of the rotor passes. |
| The upper specimen half is a solid disc, which under the pressure and temperature of the Mooney Viscometer die cavity, combines with the lower specimen half to form a homogenous capsule. |
| The combined volume of the two specimen halves is stipulated as 25 ± 3 cm³. The volume may be calculated as a function of the mass, provided the relative density is known. Therefore, it is necessary to first determine the density of the subject material, then adjust the mass accordingly (± 3 g) after the specimens are die cut. |
| The CCSi lower Mooney viscometer specimen die is of a unique and innovative design, engineered to provide an orifice for the rotor shaft when the specimen is cut... a time saving feature. The orifice is actually a ‘bore through’, which facilitates the removal of the excess material. |

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. |
