Moving Die Rheometer (MDR)

Moving Die Rheometers | ASTM D5289 & ISO 6502-3 Rubber Cure Testing

A moving die rheometer measures how a rubber compound cures by oscillating a sealed die cavity and recording the torque rise as crosslinks form. Compounders, tire plants, and QC labs read minimum torque, maximum torque, scorch time, and t90 from the cure curve. Qualitest supplies rotorless curemeters built to ASTM D5289 and ISO 6502-3. Each removes the rotor cleanup step that slows oscillating disc testing.

The range covers two configurations. One is a high-capacity automated system for shift-length unattended runs. The other is a precision instrument with micrometric die gap control and a compact loader. Both report the full cure parameter set through PC software.

Applications

Moving die rheometers sit in the mixing room, the QC lab, and the compound development bench wherever vulcanized elastomers are produced. The cure curve drives cycle time and release decisions across all three settings.

Tire Manufacturing: sets press cycle times from measured t90 on tread, sidewall, and inner liner stocks.
Compound Development: compares cure rate and torque rise as accelerator, sulfur, and filler loadings change.
Technical Rubber Goods: verifies batch consistency in seals, gaskets, O-rings, and molded parts before production molding.
Hose and Belt Production: confirms that layered compounds vulcanize together within one press cycle.
Wire and Cable Jacketing: checks scorch safety on continuous vulcanization compounds to avoid premature crosslinking in the extruder.
Automotive Component Supply: produces traceable cure curves for PPAP and IATF 16949 documentation.
Incoming Material Inspection: screens purchased masterbatch against a reference curve before it reaches the mixer.
Cellular and Sponge Rubber: tracks cavity pressure alongside torque to study expansion during cure.

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.
