A batch of lithium-ion battery cells fails stress testing at a Melbourne manufacturing facility. The cause isn’t faulty chemistry or contaminated materials – it’s inconsistent mixing during electrode slurry preparation. Each technician’s approach varies slightly, creating microscopic variations that compound into performance differences across the entire batch. The result: delayed shipments, wasted materials and questions about process reliability.
This scenario reflects challenges facing Australian manufacturing as the country builds its battery industry and medical device capabilities. In sectors where precision matters most, the humble mixing process has become a critical bottleneck.

Battery development, pharmaceuticals and advanced manufacturing share a common vulnerability: they depend on exact material preparation. When mixing fails, the consequences cascade through entire production runs.
Australia’s National Battery Strategy acknowledges these current production and quality challenges in domestic battery manufacturing. The 2024 strategy emphasises the need for standardisation and process consistency to strengthen the domestic industry. Meanwhile, Australian battery companies like Redflow have experienced early failures requiring warranty replacements, often traced back to variations in electrode preparation.
In pharmaceutical manufacturing, the Therapeutic Goods Administration enforces Good Manufacturing Practice standards that mandate batch consistency. Problems typically arise from inadequate process controls, poor equipment maintenance or lack of validated procedures. When mixing varies between operators or shifts, the entire batch can fail quality standards.
The issue extends beyond human error. Traditional mixing methods using blades or impellers can introduce air bubbles, create uneven distribution and generate heat that damages sensitive materials. Each variable adds uncertainty to what should be a predictable process.
Planetary Mixing Technology
Planetary mixing addresses these problems through a blade-less approach that combines two types of rotation. The mixing container revolves around a central axis while simultaneously rotating on its own axis – similar to how planets orbit the sun whilst spinning.
This dual-axis mechanism creates complex three-dimensional flow patterns that ensure thorough mixing without traditional mixing blades. Materials experience consistent forces throughout the container, eliminating dead spots and reducing operator-dependent variations.
The technology excels with high-viscosity materials, powders and pastes that challenge conventional mixers. Research published in Chemical Engineering Science demonstrates that blade-less planetary mixers achieve efficient mixing through combined rotation and revolution, providing productivity gains via faster mixing cycles and better consistency.
The Australian Distribution Deal
THINKY Corporation Japan has appointed AusOptic International as its official distributor for planetary mixers across Australia and New Zealand, effective 1 June. The partnership will supply THINKY’s mixing technology to battery development, medical device manufacturing, pharmaceuticals, aerospace and defence sectors.
AusOptic brings three decades of experience supporting scientific and telecommunications sectors. The Sydney-based company already serves clients in telecommunications, data centres and scientific equipment across the region, providing local service and technical support for network infrastructure and photonics research.
‘The precise and repeatable control of THINKY Mixer technology enables enhanced formulation quality, elimination of human error, and reduced variation attributable to operator skill’, said Kevin Ledley, AusOptic’s CEO. ‘This collaboration combines THINKY’s technical expertise and global leadership in material preparation with AusOptic’s dedicated local support for Australia and New Zealand’s growing industries.’
The New ARE-312 Model
The latest ARE-312 industrial planetary mixer replaces THINKY’s successful ARE-250 model with several technical improvements. The new system delivers 20% better mixing and defoaming efficiency whilst generating less heat through a low-heat DC motor that operates 10% faster.
Computer connectivity represents a significant advance for production environments. The ARE-312 includes comprehensive data logging capabilities and an enhanced user interface with 20-program memory. This connectivity aligns with broader laboratory automation trends that emphasise AI, robotics and data integration to improve reliability and throughput.
The timing reflects growing demand for connected laboratory equipment. Laboratory technology trends in 2024 show increasing adoption of cloud-based systems and digital integration that enhance data accessibility and analysis capabilities.
Impact Across Manufacturing Sectors
Both small and large manufacturers use planetary mixers, but their needs differ significantly. Desktop units suit laboratory research and small-batch production, whilst industrial models handle larger volumes for commercial manufacturing.
The replacement of the ARE-250 with the ARE-312 signals THINKY’s recognition that industrial users need more than just mixing capability. They require data integration, process validation and repeatability that meets regulatory standards.
Battery manufacturers particularly benefit from consistent electrode slurry preparation. Variable mixing creates performance differences that become apparent during testing or field use. Medical device manufacturers face similar challenges with adhesives, encapsulants and biocompatible materials where consistency affects safety and efficacy.
The aerospace and defence sectors – both targeted by the AusOptic partnership – work with advanced composites and specialised materials that demand precise preparation. Traditional mixing methods often introduce contamination or inconsistencies that compromise performance.
The Connected Manufacturing Reality
Computer connectivity changes mixing from a manual process into part of integrated production systems. Data logging capabilities enable manufacturers to track every batch, identify trends and validate processes for regulatory compliance.
This connectivity matters increasingly as Australian manufacturing moves toward Industry 4.0 approaches that emphasise data-driven decision making and process optimisation. The ability to remotely monitor mixing parameters, receive alerts for deviations and maintain detailed batch records supports quality management systems.
For manufacturers scaling production, repeatability becomes critical. The 20-program memory allows operators to recall exact mixing parameters for different formulations, reducing setup time and eliminating guess-work. Enhanced user interfaces reduce training requirements and minimise operator error.
Looking Forward
Improved data logging and operator repeatability translate directly into higher quality and less wastage for manufacturers. The Melbourne battery facility that struggled with inconsistent electrode preparation could log every mixing cycle, identify optimal parameters and ensure every operator follows identical procedures.
As Australia expands its advanced manufacturing capabilities, precision in fundamental processes like mixing becomes increasingly important. The combination of proven planetary mixing technology with modern data connectivity addresses both current quality challenges and future scalability requirements.
