MDR Moving Die Rheometer
The MDR Elite-6300 measures the cure profile of rubber compounds at constant strain and frequency. Engineered for high-throughput laboratories, it brings precision, repeatability and data integrity to compound development and production quality control.

Engineered for Unwavering Repeatability.
Constructed with a highly rigid four-post frame to eliminate deflection, paired with a precision-sealed cavity that guarantees identical testing conditions from the first cycle to the last.
Direct drive
A direct drive motor applies precise oscillation with Dyna Pro software control, eliminating the need for mechanical spacers or routine re-calibration.
Live cure curve
Elastic torque, viscous torque and tan δ are all drawn live on one graph as the test runs, not reconstructed afterwards.
Rotorless cavity
Optimised thermal recovery. The absence of a rotor ensures dies return to the set temperature significantly faster after loading compared to traditional oscillating disc rheometers.
Sealed under pneumatic load
High-pressure pneumatic seals ensure acute die alignment, firmly securing the cavity on every load to prevent compound extrusion and maintain exact volume.
Isothermal and non-isothermal
Upper and lower dies are controlled separately, so the cavity can hold an isotherm or follow a programmed ramp. Non-isothermal cure needs the cooling option.
Grooved biconical dies
Cruciform-less dies featuring optimised groove profiles strictly minimise slippage on stiffer stocks, ensuring torque readings reflect pure material properties.
Every cure parameter
ML, MH, MH−ML, scorch time, maximum cure rate and the time it occurs all come off one run, alongside more than a hundred other process parameters.
Engineered for Minimal Downtime.
Designed with user-replaceable seals and straightforward calibration protocols, empowering your facility's technicians to maintain peak operational efficiency without requiring idle time for external service visits.

Discuss Your Rubber Cure Testing Requirements.
Tell us about your rubber compound, test method and laboratory workflow. DAK Engineering can help you select the MDR configuration and reporting options for your cure testing requirements.
The MDR answers how a compound cures. If you also need to know how it processes before cure and how it behaves after — across strain, frequency and temperature, on one specimen — that is the Rubber Process Analyser.
