MOVING DIE RHEOMETER : HIWA 900

The HIWA 900 Rheometer is used for measuring the curing characteristics of rubber vs. time at constant temperature . In Hiwa 900 Rheometer , rubber paste is placed between dies under constant temperature and mechanical deformation is continuously applied to it by an oscillating die . The oscillation of die can be adjusted mechanically at angles ±0.5°, ±1°, ±3° . Before test execution , dies is heated up to predefined temperature . After placing of specimen , two die sealing plates are closed by a pnumatic cylinder. Rubber starts to cure and die starts to oscillate . The necessary torque for oscillating motion is increased gradually by curing of rubber paste . The magnitude of torque is measured by electronic system and simultaneously the torque - time curve is monitored by computer. After ending of test the two dies are opened by pnumatic cylinder and the cured specimen can be drawn out easily . The machine is fully controlled by a software via a computer attached to the machine . The software is so designed that training can be done in very short time and It is userfriendly.
