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​
