ROTOR
automotive vacuum pumps
Core Technologies Held
Multi-stage Cold Forging Forming Technology → Rotor component for automotive vacuum pumps.
Usage and Key Functions
- A part that determines rotation speed and suction cycle by repeating contraction and expansion as it rotates around the axis of the cylinder, utilizing cam motion
- Exhibits superior performance in durability, high stiffness, high strength, and wear resistance, even under harsh conditions like vibration, moisture, and dust
- Secured forming technology that minimizes post-processing of forged products compared to conventional turning processes, based on the quantification of materials
