Advantages:

1)      Directional Flow: The elliptical hole provides a larger effective opening in the long axis direction, which is suitable for particle directional screening or fluid diversion needs.

2)      Strong Anti-deformation Ability: The hole shape has a smooth arc, uniform stress distribution, and is resistant to high-frequency vibration and lateral load impact.

3)      Aesthetic Adaptability: The elliptical hole is flexibly arranged to create a dynamic visual effect.
