Oscillating Disc Rheometer
Oscillating Disc Rheometer shows a typical Cure Curve obtained in the software test screen. The curve of Torque V/s Cure Time depicts all the vulcanization characteristics of the Rubber Compound and that can be determined directly. XY Plot of Torque (F) against real cure time is called Rheometer graph. Rheometer graph is displayed in real time and at the end of test time, software and displayed on the screen.

- Helps reducing the time taken to process and minimum wastage
It is an instrument consisting of a motor driven disk within a die cavity formed by two dies maintained at specified conditions of temperature and die closure force. It measures the effect of temperature and time on viscosity of rubber or compound.
MOONEY VISCOSITY
It is a measure of the viscosity of a rubber or compound determined in a Mooney shearing disk viscometer. It is indicated by the torque required to rotate the disk embedded in a rubber/compound specimen and enclosed in the die cavity under specified conditions.
Viscosity of rubber or compound plays vital role in deciding its processing behaviour. In Rubber Industry rubber or compound have to undergo
MOONEY VISCOMETER
various processing before it can be vulcanized into its final form. Deviation in viscosity of the compound will critically alter its processibility specially in terms of calendering, extruding or injection moulding. It is necessary that viscosity parameter be maintained within specified limits.
To do this Mooney Viscometer is of vital importance. In fact viscometer has manifold advantages.
Micro Vision’s high precision instrument – Moving Die Rheometer offers sensitivity and reliability of measurement for the evaluation of Vulcanization properties of rubber.
Using world class technology, it has been developed to determine the elasticity of vulcanization, the cure rate, cure speed and examine the behavior of rubber mixture post. vulcanization, All the more, with MV’s Moving Die Rheometer , the viscous and elastic fraction of the rubber mixture.
With the help of our product, an expert can easily monitor the initial trough ie. processing behavior of the compound and the final shape of the curve.
Principle
How does it works ?
The rubber test piece is contained in a unique designed bi-conical die capacity and also maintained at a stable die temperature, Through the oscillating lower die ot small rotary amplitude. a precise transducer will measure the reaction torque of vulcanizing rubber, MV’s accurate temperature control and torque measurement ensures the later temperature response, greater repeatability and reproducibility of test result
Resulting in measurement of accurate scorch time and cure time, it can accurately measure and analyze the viscous and elastic properties of vulcanizing rubber.
MDR Prime has been engineered to match international standards and is comparable with leading global brands, German/USA-manufactured MDR systems in terms of technology, components, and performance.
The system incorporates a high-precision torque sensor from Interface Inc., directly mounted on the upper die. This configuration ensures lossless torque measurement. In many conventional designs, the torque sensor is mounted on the lower shaft, which can introduce torque losses and lead to fluctuations in repeatability, particularly when testing soft compounds with low torque values.
MDR Prime has been designed with superior fit and finish, developed specifically for export markets and refined through valuable feedback from Indian customers. The machine delivers highly accurate and consistent results comparable to imported international machines.
The development of MDR Prime is the result of extensive research and continuous improvement, building upon over 15 years of experience manufacturing the MDR Basic model and addressing its operational limitations.
All components used in MDR Prime conform to international quality standards and are selected to ensure long service life, operational stability, and minimal maintenance requirements, providing reliable performance over extended periods of operation.
