MDR 3000 Basic
Moving Die Rheometer

Rotorless moving die rheometer for rubber compound testing configurable to oscillations of
±0.2° (±2.8%), ±0.5° (±7%), ±1° (±14%), ±3° (±42%)

The MDR 3000 Basic rheometer is designed for measuring the viscoelastic properties of elastomeric and rubber compounds before, during and after cure according to ISO 6502, ASTM D5289 and DIN 53529.

The MDR 3000 Basic is used to determine the plasticity of vulcanization, the cure rate, and to examine the behavior of the rubber mixture at post-vulcanization. Further, it is possible to determine, the viscous and elastic fraction (S 'and S'') of the rubber mixture.

The determined measurements such as torque, viscous and elastic component for the upper and lower halves of the test chamber are displayed on the screen as a function of time. The acquired data gives exact information about processability, cure characteristics, cure speed, and behavior of the compound after vulcanization.

System Description


The testing instrument consists of the machine case, a PC with screen, keyboard and mouse as well as a printer.

The test chamber is equipped with a pneumatic closing device, with a closing force of 11.6 kN equipped. The opening of the test chamber is at any time possible. Between measurements, the test chamber can be manually closed in standby mode.

To protect the user a safety shield is lowered before the test chamber is closed. Between tests the test chamber can manually be closed in a standby mode. A delay time for opening the safety shield can freely be configured in the software. Furthermore there is the possibility of the attachment of a suction for produced waste gas to the back of the instrument.

The temperature of the two test chamber halves are independently measured by means of PT 100 RTDs and heating is controlled via software.

The rubber mixture sample is tested under torsion generated by rotational vibration of the lower test chamber. The lower test chamber generates sinusoidal rotational vibrations with fixed-angle amplitude. The oscillation amplitude can be adjusted to ±0.2°,0.5°, 1° or 3°. The torque is measured via a strain gauge torque transducer with very high resolution.

Due to the rugged construction of the MDR 3000 Basic, it can be used for quality control purposes not only in the laboratory, but also directly in the production area.

The data acquisition and the control of the testing instrument is made by the PC by means of the included MonControl analysis software. For the storage and analysis of the determined measurement data a modern SQL database structure is provided. Over 1,500 time and torque characteristics are available for the selection of the test results from the viscous and elastic portions of the mixture.

 

Test chamber system

The two test chamber halves form a closed, bi-conical system. That means the test chamber is formed by two conical test dies. This ensures a constant shear rate which is independent of the die radius in the sample.

The test chamber is equipped with a pneumatic closing system, which moves the upper test chamber half to the lower test chamber half to completely close the test chamber and keep the test sample during the test or cure under pressure. The default closing force is 11,6 kN at 4,5 bar air pressure.

During the test the lower die performs a sinusoidal movement with a mechanically fixed amplitude and a fixed frequency. This movement is generated by a high precision motor system with adapted gear head. This motor is regulated by a high-resolution motor controller - this controller is directly integrated into the motor housing. The drive system is safeguarded by motor overload protection and will be switched off if the maximum permitted torque is exceeded.

The measurement of the reaction torque is made by a DMS torque transducer with a very high resolution which is directly mounted above the upper test die. With this transducer it is also possible to measure the current pressure in the test chamber (optional).

The temperature control of both electrically heated test dies is made by the MonControl Analyses Software with a separate control system for each test die.

The temperature control and temperature measurement is performed by PT 100 resistance thermometers. For the heating of both test dies a heating film is used - one film for each test die. The heating film has a spiral shape with different distances between the windings. Therefore a heat concentration is prevented and a uniform temperature spreading is ensured.

Rheometer Volume Punch

For the exact production of test samples for the MDR 3000 Basic, the R-VS 3000 sample cutter for rheometers is an available option. This volume punch is used for rapid and accurate preparation of test specimens. The usage of a volume cutter is recommended because this ensures reliable and reproducible test results.
