Скачать или смотреть Step Four in Neodymium Magnet Production Pressing and Pre Sintering Preparation

“Continue the journey with us in the production of sintered neodymium magnets as we reach the crucial pressing stage. This video explores how qualified magnetic powder is carefully placed into molds and pressed to form the initial shapes of the magnets, known as ‘green bodies’ or ‘compacts’.

Process Overview:

1. Filling the Molds: We start by filling the molds with the fine magnetic powder prepared in previous stages.
2. Pressing: A top press comes down to compact the powder into the shape of the magnet, forming the green body.
3. Wrapping in Plastic Film: Each compact is then wrapped in a thin plastic film to prepare it for isostatic pressing, which helps to enhance the density of the compact.
4. Isostatic Pressing: The wrapped compacts are subjected to further pressing under equal pressure from all directions to improve their density and strength.
5. Plastic Film Removal: Post pressing, the compacts are placed in a vacuum environment to remove the plastic film, preparing them for the final sintering process.

This video will give you a detailed look at how these steps are meticulously performed to ensure the highest quality of the magnets before they head into sintering, the final phase that fully solidifies their structure.
