MobilityMiniaturization and Light Weight

Achieved process reduction and structural freedom through phenolic resin molding,
contributing to the miniaturization and weight reduction of metal substitute parts.

Line of high dimensional accuracy
Phenolic molding compound SiON®

We continue challenge for realization of "Non-machining process" which has been hoped for long time.

Advantage

  • Excellent dimensional accuracy in continuous molding process
  • Low dimensional change in environment for use
  • Low CTE
  • Low anisotropy
  • Collarless is possible by high creep resistant
