The technical group of mixing, kneading and forming plans and conducts a factory tour and a lecture under the slogan of “taking a lesson from the past” and “state-of-the-art” concerning the subjects that the group is involved with. In addition, the group aims at establishing the evaluation method of each state of mixture, kneading, and molding/casting in a pharmaceuticals and ceramics manufacturing where mixing and molding/casting are key processes. The group proceeds with the investigation to the goal of standardization in “evaluation method of kneading state” by organizing a subcommittee
Current level of technology, trend and activities in future
- Uniform mixing and kneading: Compounding and multiple function of equipment as well as accurate control of operations are demanded corresponding to the diversity of mixing and kneading materials and high-mix low-volume production. Simulation-based design of equipment by numerical analysis such as DEM simulation is being developed in the field of mixing and kneading. Also, mixing and kneading technologies for cohesive powders and minor constituents is demanded.
- Micro and nanoscale mixing and kneading: Mixing and kneading are the key technology for particle compounding. Nanoscale accurate agglutination of different kinds of particles and uniform dispersion in matrix is indispensable in the fields 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 shape which restrains change of shape in the forming process is demanded. Forming operations precisely controlled, microscale mixing, surface modification and design of particle size distribution and particle shape are important as technology for greater 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. It is also demanded to develop equipment efficiently and to develop the proper evaluation method of mixing and kneading necessary for appropriate setting of operational conditions. Evaluation methods of mixing state and characteristic properties of kneading machine have been examined in the group. The group will try to standardize the evaluation methods based on such work.
