Moving Die Rheometer (MDR)

Moving Die Rheometer Range

Two instruments cover the range. They differ mainly in automation capacity, temperature ceiling, and how far the test conditions can be varied.

Automatic Moving Die Rheometer - QualiMDR™ A

A rotorless curemeter for high-throughput laboratories, with a feeder holding 15, 30, or 120 specimens for shift-length unattended running. Torque reaches 225 dNm and the sealed cavity pressurizes to 8,300 kPa, covering truck tire stocks and soft silicones alike. An optional variable frequency mode (0.001 to 50 Hz) adds frequency and strain sweep work. An MES interface pushes results into plant systems.

MDR Moving Die Rheometer – Rheocheck MD Drive

A precision curemeter for laboratories that prioritize measurement traceability over batch volume. Micrometric vernier adjustment sets the die gap to ISO 6502-3 requirements, and PID controllers hold die temperature to 0.1 °C resolution up to 250 °C. A supplied torque calibrator lets operators verify readings on a routine schedule. The 5-position loader and SQL-backed data management suit regulated QC environments.

How to Choose the Right Moving Die Rheometer

• For shift-length unattended testing: choose the QualiMDR™ A, whose 15, 30, or 120 sample feeder covers a full production run without an operator at the machine.
• For traceable calibration and audit-ready records: choose the Rheocheck MD Drive for its supplied torque calibrator, SQL database, and calibration report tied to primary standards.
• For high-temperature cure profiles: the Rheocheck MD Drive reaches 250 °C, above the 210 °C standard ceiling of the QualiMDR™ A.
• For heavily loaded or very soft compounds: the QualiMDR™ A spans 0.01 to 225 dNm, with an optional 0.01 to 50 dNm range for silicone and latex stocks.
• For frequency and strain sweep research: the QualiMDR™ A variable frequency option covers 0.001 to 50 Hz and arcs from 0.001° to 90°.
• For cellular rubber and expansion studies: both accept a cavity pressure channel that records pressure alongside torque.
• For a lab that runs a handful of tests per day: the Rheocheck MD Drive with its 5-sample loader avoids paying for capacity you will not use.
