Linear Automation

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.

Autoloading Tray

Tray Automation

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.

Die Cavity Pressure Measurement System

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.

Die Cavity Pressure Control System

With this option, cavity pressure can also be controlled either to a programmed or an on-line calculated pressure level. The closing force and die gap are designed as a variable, independent axis so that the cavity pressure can be controlled. This system is especially suitable for test sequences that include curing and a cool-down of the sample for a dynamical mechanical analysis. This system can be utilized to compensate for material shrinkage to avoid any slippage in the test chamber. This technology is patented worldwide by MonTech.

  • Isothermal Cure

    Isothermal cure experiments are the most common quality control test in rubber and elastomer processing. With over 3500 data points available on MonControl, all characteristics including minimum / maximum elastic torque, scorch times, cure times and reaction rates are precisely calculated.

    Pass / fail statuses and tolerance gates can be easily set and evaluated with each test.

    Isothermal Cure
  • Cure with Simultaneous Sponging / Foaming / Blowing Reaction

    Taking place during the curing process, foaming reactions produce cellular membrane-like structures within mixes and are vital part of compound development. The cellular matrix created during the foaming reaction reduces density, increases thermal and acoustic insulation, and affects the stiffness of the mix.

    MonTech rheometers are optionally equipped with a precision normal force transducer in the die cavity. This advanced transducer reveals interrelations between the simultaneous cure and foaming reaction.

    MDR simultaneous curing
  • Non-Isothermal Cure

    MonTech MDRs and RPAs can be programmed to follow any non-isothermal temperature profile to simulate mixing, milling, extrusion, compression molding, injection molding and storage conditions.

    Non-isothermal test sequences are executed in a single test and can be included with other dynamic tests for the most accurate data discerning material behavior.

    non-isothermal cure
  • Advanced Cure Kinetics Modeling

    Test data from similar static or dynamic test sequences executed at different temperatures are evaluated and modeled for an advanced cure kinetics analysis.

    Information acquired includes: Reaction Rate, Order of Reaction (n), Rate Constant (k), Activation Energy (E) and Incubation Time (ti).
