DIANET Horizontal Magnetic Field Molding

OUTLINE

Manufactured by an integrated process extending from raw materials to finishing, our DIANET is a samarium-cobalt (SmCo) magnet offering high performance, accuracy, and quality.
DIANET used in stepping motors for wristwatches, but they are used in other, ever expanding, applications, including microelectronic parts for audio and
telecommunications devices; reflow-mounted thin, compact devices; and microelectromechanical systems (MEMS).

  Modlding Model Sample, Drection Of Magnetic Field

FEATURES

  • Superior heat resistance and reflow mountable
  • Superior corrosion resistance, without deterioration of magnetic properties
  • No processing-related deterioration of magnetic properties, thus ontributing to equipment downsizing and reduced energy consumption
  • Useful in applications having a dimensional tolerance on the scale of microns, made possible by our proprietary precision processing technology
  • Minimum magnetic characteristic variations, made possible by our proprietary manufacturing technology, thus contributing to device stabilization
  • Simple, ultra-precise compact shape, so cost performance is excellent, made possible by our proprietary near net shape processing technology

APPLICATIONS

  • Watch rotor
  • Coreless motor
  • Motors such as high-performance compact actuators
  • Telecommunications devices
