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 technology: In response to the needs for diversification of materials to be mixed and kneaded, and for high-mix low-volume production of a wide variety of products, complex and multifunctional equipment and precise control operation technology are required. For this purpose, equipment design based on numerical experiments such as DEM simulation is underway. In addition, mixing and kneading technology for uniform mixing and kneading of highly adhesive and cohesive powders and trace components is required.
Automation of mixing and kneading operations: Due to the decrease in the working population and other factors, there is a serious shortage of labor, and unmanned and automated powder operations are needed from the perspective of preventing contamination caused by humans.
Highly controlled molding: Near-net shaping that minimizes shape change during molding is required, and precisely controlled molding operations and particle design such as fine mixing, surface modification, particle size distribution and particle shape are important for the refinement and advancement of molding operations and for controlling obstacles during molding. In particular, metal 3D printer technology has recently attracted attention in which a laser or electron beam is controlled and irradiated by CAM software onto metal powders laid in layers and the layers are piled up while being partially melt molding. It is necessary to respond to this new powder molding method.
Standardization of evaluation methods for mixing, kneading, and molding conditions
The future challenge is to predict the characteristics and quality of molded products from the characteristics of the raw material powders and mixed/ kneaded products. It is necessary to develop an appropriate evaluation method for mixing and kneading conditions, which are important for the development of efficient equipment and the setting of operating conditions, and standardization of evaluation methods for kneading conditions and kneading machine characteristics, including those discussed in this technical group.
