The Technical Group of Mixing, Kneading and Forming plans and conducts a factory tour and a lecture meeting under the slogan of “take a lesson from the past, get the latest knowledge” and “leading-edge technology”. In addition, the group tries to establish the evaluation method of mixture, kneading and forming. Such an evaluation method is important in pharmaceutical and ceramic areas where mixing and forming are key processes. The group organizes a subcommittee within it, and proceeds with the investigation toward the goal of standardization “evaluation method of kneading state”
Current level of technology, trend and activities in future
- Uniform mixing and kneading: Compound equipment, multiple function and accurate control of operations are demanded in response to the diversity of mixing and kneading materials and the need of high-mix low-volume production. To meet such demand, equipment design based on numerical simulation such as DEM (Distinct Element Method) is being developed. Also, uniform mixing and kneading for cohesive powders and minor constituents is required..
- Micro and nanoscale mixing and kneading: Mixing and kneading is the key technology for particle compounding. Nanoscale accurate agglutination of different kinds of particles and uniform dispersion in matrix is indispensable in the industrial usage of pharmaceutical products, battery, electronic materials and nanoscale materials such as carbon-nanotube. Not only mechanical methods but also surface-chemistry-based methods which control mutual interaction between particles and between particles and matrix are necessary. At the same time, technology which restrains contamination occurring in the process of nanoscale mixing and dispersion is needed.
- Highly controlled forming: Near-net shaping which restrains change of shape in the forming process is demanded. Precisely controlled forming operations, microscale mixing, surface modification and design/control of particle size distribution and particle shape are important as the technology for more sophistication and means which restrain obstacle in the forming process.
- Standardization of evaluation methods of mixing, kneading and forming: It will be a future assignment to predict properties and qualities of compact products from the raw state of materials and from characteristic properties of mixed and kneaded materials. A proper evaluation method of mixing and kneading should be established for efficient development of equipment and setting the operational conditions. The group examines the evaluation method of mixing state and characteristic properties of kneading machine, and will try to standardize the evaluation methods based on such work.
