What is the curved design of a wiper blade and what does it do?

1. Better contact with glass surface:

The curves of the wiper blades are designed to ensure a perfect fit between the blades and the windshield. For example, Ningbo Zhenhai Jinjian Autoparts Limited Company wipers use unique Smart Flex technology, which allows the blades to bend to adapt to the curvature of different windshields. This design ensures that the wiper blades can fit tightly against the glass and effectively scrape away rainwater and other impurities.

2. Uniform wiping effect:

The curved design helps ensure that the entire car wipers blade maintains even pressure as it moves, allowing it to wipe evenly across the glass surface. For example, Ningbo Zhenhai Jinjian Autoparts Limited Company wipers use a multi-point pressure system to ensure that the blades can evenly contact the windshield at different parts, thereby achieving a more consistent wiping effect.

3. Reduce noise and jitter:

The curved design helps reduce noise and vibration when the wiper moves. Ningbo Zhenhai Jinjian Autoparts Limited Company's Aerotwin wipers adopt a hyperbolic design, which reduces air resistance and vibration, making the wiper quieter during operation and improving driving comfort. This is important when driving at high speeds or in adverse weather conditions.

4. Improve durability:

The curved design helps improve wiper durability by reducing overall stress on the wiper blades. For example, the Ningbo Zhenhai Jinjian Autoparts Limited Company wiper adopts a curved shape, which disperses the stress points on the blade, reducing fatigue damage caused by frequent movement and deformation, thereby extending the service life of the wiper.
