Tungsten Steel Mould for Magnetic Materials

This tungsten carbide mold is specially designed for powder compaction of magnetic materials, made of high-quality cemented carbide raw material. The die adopts tungsten carbide insert construction, and punches are available in non-magnetic tungsten carbide or steel material. The tungsten carbide insert features high hardness and outstanding wear resistance to maintain stable cavity dimension during long-term operation. Non-magnetic punches prevent magnetic powder adhesion during compaction, while steel punches provide better cost performance. Materials can be flexibly selected according to customers’ products and production conditions. The whole mold achieves micron-level dimensional accuracy with superior surface finish. It can effectively reduce magnetic powder sticking, ensure uniform density and stable shape of formed magnetic parts, greatly extend mold service life, and is widely used in mass production of various magnetic components including permanent magnet and soft magnet.
