QM310S Heating Internal Mixer

The QM310S heating internal mixer is a closed, high-filler mixing unit for rubber and plastic raw materials, aimed at formulation R&D and small-batch trial mixing; rotor shear disperses fillers evenly into the polymer.

The heated chamber with real-time torque/temperature monitoring lets operators observe powder uptake, dispersion and curing/plasticizing during mixing, supporting rheology R&D and formulation evaluation.

Closed mixing keeps dust low and batches small and flexible; paired with an open mill for sheeting and a curemeter for testing, it forms a complete mixing-to-evaluation process chain.

Closed mixing suits high-filler formulations with low dust and even dispersion.

Heated Chamber

The chamber is heated and temperature-controlled to simulate real processing thermal history.

Process Monitoring

Torque and temperature are displayed in real time and the whole mixing process is logged.

Rheology R&D

Observe powder uptake and dispersion to guide formulations and process windows.

Flexible Small-Batch

Small batches and fast cleaning, ideal for R&D and multi-formulation comparison.

Closed Internal Mixer
Small-Batch Trial Mixing for Formulation R&D

The QM310S heating internal mixer is a closed mixing unit for rubber and plastic raw materials; rotor shear disperses fillers, additives and polymers evenly for formulation R&D and small-batch trial mixing. The heated chamber with real-time torque/temperature monitoring lets operators observe powder uptake, dispersion and plasticizing during mixing to capture rheology and process-window information.

From formulation screening to process optimization - the internal mixer's closed mixing keeps dust low and batches small and flexible, while the torque curve reflects material dispersion in real time. Paired with the QM300 open mill for sheeting and a curemeter for testing, it forms a complete mixing-to-evaluation chain - a core instrument for polymer formulation R&D.

Designed for formulation R&D evaluation - closed mixing plus real-time torque monitoring for small-batch rheology and process windows.
