Powder molding! Densification of metal, alloy, and ceramic powders without binders.
By forming powder without a binder and without exposing it to high temperatures for extended periods, we achieve both "suppression of material performance degradation due to heat" and "densification (high density)!"
At Asahi Kasei Corporation, we utilize the explosive energy of explosives for the crimping and molding of dissimilar metals, as well as the fabrication of metal components. By using the ultra-high pressure generated by the explosive energy of explosives, we can achieve binderless compression molding of metal, alloys, and ceramic powders. This allows for increased density and enhanced performance. Additionally, since the compression using this technology occurs instantaneously, the materials are not exposed to high temperatures for extended periods, making it particularly effective for materials that may deteriorate at high temperatures. For more details on what types of powders can be compressed, please feel free to contact us.

Company information
BA Clad is a clad steel plate manufactured by Asahi Kasei using the explosive welding method, and it has received high praise in various fields since its launch. The explosive welding method utilizes the enormous energy released during an explosion to instantaneously bond metal plates together, thereby producing clad steel plates. BA Clad is used for plants and equipment in the chemical industry, petroleum refining, petrochemicals, and power generation, and is exported widely both domestically and internationally, either as flat plates or various components. It is used as corrosion-resistant and heat-resistant structural materials for power plant condenser tube sheets, heat exchanger tube sheets for chemical plants, shells, and end plates, among others, and its applications are continually expanding to include rolling mill liners, electrodes, ultra-low temperature joints, ultra-high vacuum joints, and structural joints for ships and LNG tankers. We propose solutions related to metal joining (dissimilar metal joining, similar metal joining) and cladding. We can provide joining characteristics such as material properties, joining strength, minimization of alloying at the joining interface, and joining area that are difficult to achieve with other joining methods, such as various welding techniques, diffusion bonding (roll bonding, HIP, etc.), friction joining (friction welding, friction stir welding (FSW)), electromagnetic pressure welding, brazing, plating, and thermal spraying.
