In the world of modern materials manufacturing, internal mixers—also known as Banbury mixers—have become indispensable for processing high-viscosity compounds with speed, consistency, and superior homogenization. From rubber compounding to thermoplastic blending, these robust machines are the backbone of industries ranging from automotive and footwear to electronics and medical devices.
At Ollital, we specialize in the design and production of high-performance internal mixing machines that deliver industry-leading efficiency, repeatability, and reliability. Whether you operate a research lab, a small production line, or a large-scale industrial facility, our mixers are engineered to meet the most demanding material requirements.
An internal mixer is a batch mixing machine that uses twin rotors enclosed in a compression chamber to thoroughly mix rubber or plastic with fillers, oils, additives, and pigments. Unlike open mills or extruders, internal mixers allow high-pressure, high-shear mixing, enabling fast dispersion and uniform compound development—especially for high-viscosity materials like synthetic rubber or thermoplastic elastomers (TPEs).
Key benefits include:
l Short mixing cycles with high torque
l Consistent compound quality across batches
l Reduced dust and volatile emissions
l Improved operator safety
l Energy-efficient and automation-ready designs

l Improved filler dispersion and tensile properties
l Lower scrap rates and batch variability
l Cleaner, more ergonomic workspaces
Real-world example:
A Southeast Asian automotive supplier upgraded to our MX-V50 system and improved batch consistency for their EPDM compounds by over 30%, while reducing operator workload and dust exposure by half.
For high-output production environments, our internal mixers can be fully integrated into automated lines, including:
l Automatic weighing & dosing systems
l Conveyor feeding & discharge
l Downstream extrusion or pelletizing
l Real-time data logging for process monitoring
l SCADA integration for full plant visibility
Whether you’re scaling up or streamlining, we provide full system engineering and post-sale support to ensure a smooth integration.
