< Flow control forming, teeth shape forming, precise shearing > An innovative plasticity manufacturer by cold forging and press technologies

Sprocket (Driven)

  • · We achieved near-net-shaped product from parts former slag to cold forging process.
  • · We developed clear press cut technique on outer gear as well as succeeded in reducing the machining process cost drastically to abolish automatic lathe turnings on gear.
  • · We also guarantee the tolerance against frictional wear and tipping.
