Powder molding! High-density formation of metal, alloy, and ceramic powders without binders.
By forming powder without a binder and without exposing it to high temperatures for long 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 from the explosive energy, we can achieve binderless compaction molding of metals, alloys, and ceramic powders. This allows for increased density and enhanced performance. Additionally, since the compaction using this technology occurs instantaneously, the materials are not exposed to high temperatures for extended periods, making it particularly effective for materials that may degrade at high temperatures. For more details on what types of powders can be compacted, please feel free to contact us.

Company information
BA Clad is a clad steel plate manufactured by Asahi Kasei using the explosive cladding method, and it has received high praise in various fields since its release. The explosive cladding 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, cryogenic joints, ultra-high vacuum joints, and structural joints for ships and LNG tankers. We offer 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, which 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 bonding, brazing, plating, and thermal spraying.
