Recycled Powder Core | Resource circulation and CO₂ reduction through the reuse of used cores

Using recycled powder cores to address waste reduction and CO₂ reduction while maintaining magnetic properties and moldability.

Amid demands for addressing CO₂ emissions and resource circulation of products, there are cases where companies hesitate to switch materials due to concerns such as "I want to use recycled materials, but will the magnetic properties decrease?" and "Will there be constraints on shape design and strength?" Balancing environmental impact reduction with product performance is a challenge in design and procurement. Daimat proposes a recycling technology that crushes used powder cores, processes them into powder, and then reshapes and heat-treats them back into powder cores. ■ Maintaining properties even with recycled materials ▼ Magnetic properties are equivalent to virgin materials ▼ Mechanical properties are also equivalent to virgin materials ▼ Molding properties are comparable, allowing for three-dimensional shape formation ■ Addressing resource circulation ▼ Used powder cores are crushed and processed for reuse as raw materials ▼ Connecting waste to reuse contributes to the realization of a circular economy ▼ Can be proposed as a material option for CO₂ reduction We also anticipate applications in areas requiring three-dimensional shapes, such as cores for axial gap motors. Documents summarizing the re-resource process of used powder cores and a comparison of properties with virgin materials, as well as more detailed benefits of introducing and utilizing recycled materials, can be downloaded below.
