Honseninsert magnet is made of permanent neodymium magnets, combining with steel, rubber or nylon can be made almost any shape to fix embedded part in precast concrete production. As using, the magnetic surface fix on the platform or steel shuttering, another side fix the embedded part, because of the high suction force, the embedded part can stay accurately in the precast concrete element. Honsen series insert magnets products with the advanced magnet protection system, can effectively protect the magnet from corrosion from outside material, improve the abrasion resistance, then improve the service life of the magnet.
