D-RPA 3000
Dynamic Rubber Process Analyzer
The MonTech Rubber Process Analyzer (RPA) is the most advanced dynamic rubber rheometer for attaining key data on rubber and polymer molecular properties.
Manufactured with the latest advancements in rubber rheological technology, the MonTech rubber process analyzer assists mixers and rubber product manufacturers in taking back control of their materials. The RPA reveals key properties for problem solving including the analysis of raw elastomer or compound molecular properties. Additionally, the RPA will aid in the discovery of processing indicators, vulcanized dynamic performance, process simulations and much more. Where traditional rubber rheology cannot detect challenges or material differences, the RPA finds them, identifies them, and gives users more control on how to use their rubber materials. Whether located in high-end R&D laboratories, production laboratories, or the mixing floor, the MonTech RPA is built for long-term accuracy and reliability.

Motor Matters
The heart of the Rubber Process Analyzer is its motor. Where others started, we have advanced the technology forward. Our patented Direct Drive Motor, designed exclusively for RPA applications, enables the largest dynamic range of any RPA. Featuring low friction ceramic bearings, an unbeatable data resolution, and a high-torque gearless actuator, our motor proudly stands out as the best with zero failures globally. Choosing the MonTech RPA means choosing the right motor for long term accuracy and reliability.
- Oscillatory Strain: 0.0001 – 360 ° Arc
- Oscillatory Frequency: 0.001 – 100 Hz
- Optional: Rotations Per Minute 0.01 – 900 RPM
Load. Test. Remove. Repeat.
Automation should make your life easier, not harder. Production laboratories with high testing throughput depend on reliable automation to match the number tests to accomplish. Engineered robotics, or linear film feeding, guide the sample with ease onto the die cavity where testing may commence.
Automation Types:
- Tray Autoloader: 24, 48 or 100 samples per tray
- Linear Autoloader: 5 or 10 sample linear feeding
Industrial Electronics That Endure. Controls That Deliver.
The leaders in rubber product manufacturing demand the highest standard in industrial electronics. Whether on the mixing line or operating in a QC or R&D laboratory, directing the operation of the RPA, is its PLC. Designed by one of the top three European producers of industrial PLCs, the RPA’s PLC is considered an industrial standard across high-tech industries and advanced automation applications. It’s fully digital with no analogue signal processing. If something goes wrong, the modular concept enables quick replacements if necessary and is available for remote diagnostics.
Frames Engineered
for Accuracy
The machine frame plays a major role in the long-term accuracy and stability of RPA data. Each MonTech RPA frame is built from aerospace grade aluminum and stainless steel including an 80 mm thick baseplate, 50mm pullrods, an 80 mm crosshead and 20mm thick side panels. This results in a superior frame stiffness which significantly improves repeatability, correlation, reduces damping abilities in high-frequency tests, all the while reducing the signal-to-noise ratio.
Fan-less Design: The frame’s design mitigates any form of potential heat build-up in the electronics cabinet. With no need for fans, and the frame’s sealed housing, carbon black contaminated electronic failures are a challenge of the past.

Optional Features
-
Easily improve productivity.
Linear automation systems are ideal for online testing, utilizing a fast and reliable direct conveyor feeder with the lower film as a transportation carrier.
5 or 10 Samples.
Ideal for online automated testing, this system features automated sample loading and unloading with a linear queue of either 5 or 10 test samples at a time.
Linear automation systems are always the preferred choice for very sticky materials such as silicones or glue that sample loading arm systems might not be able to handle.
Maximum Efficiency
Tray automation systems allow users to queue larger amounts of samples and leave the testing system running totally unattended over long periods. With MonTech's patented direct sample hadling system, sample placement accuracy and test result repeatability is significantly increased. Samples are handled and monitored by a high-volume vacuum system, ensuring perfect sample pickup, transporation and drop-off - even for less than ideal test samples.
24, 48, or 100 Samples Tray
This system features automated sample loading and unloading with a direct tray-to-chamber handling system.

- Designed for calibrating MDR Torque
- Certificate of ISO/IEC17025 Accredited Calibration Included
MDR torque measurements are performed by a high-resolution DMS strain gage sensor inside the machine which should be calibrated at regular intervals. The MDR Torque Calibration Standard is specifically designed to accurately calibrate this strain gage sensor with a high degree of precision. The concave surfaces of the standard are precision-machined to fit the bi-conical dies of the MDR. This design allows the standard to be self-seating – minimizing cosine error and ensuring accurate and precise calibration.

The system includes a combined force / torque transducer and a 2-channel amplifier system for real-time simultaneous measurements of torque and force. This system measures the normal force to calculate pressure within the rheometer's die cavity. The force transducer and amplifier are balanced automatically before each test. Measuring the pressure and torque simultaneously is an easy way to quantify the expansion/contraction of the compound before, during, and after vulcanization.

The advanced cooling system features a liquid cooling system with an external chiller unit. The cooling system works as an addition to the pneumatic cooling system. If lower temperatures are required, the chiller unit will begin cooling down the dies to as low as -40°C. Both dies are separately chilled and cooled by the external unit connected to the instrument. The liquid cooling system is able to run anything from sample curing down to glass transition testing.
The heating system of the dies remains unchanged; instruments equipped with this chiller unit maintain the functions of a Moving Die Rheometer or Rubber Process Analyzer.
This technology is patented worldwide by MonTech
