Automobile Damping and Silencing Sheet DC40-02A4

Short Description:

The automobile damping and silencing pad is an accessory used to reduce or eliminate the noise during brak-ing. It is an important component of the automobile brake pad. It is arranged on the steel back of the brake pad. When the brake pad is braking,it plays a certain damping effect on the vibration and noise caused by the brakepad pad pad. The brake system is mainly composed of brake lining (friction material), steel back (metal part) and damping and silencing pads.

Products Description

Automotive vibration damping and muffler pads are essential components within automotive braking systems, designed to mitigate or eliminate braking noise. These pads serve as a critical element of automobile brake systems and are integrated onto the steel backing of brake pads. During braking, they effectively dampen vibrations and reduce noise generated by the brake pads, ensuring smoother and quieter braking performance. The brake system comprises three primary components: the friction lining (friction material), the steel backing (metal part), and the vibration damping and noise-reduction pad.

Noise Reduction Principle
Brake noise originates from the frictional vibration between the friction lining and the brake disc. As sound waves propagate from the friction lining to the steel backing and subsequently to the damping pad, their intensity undergoes transformations. The phase impedance mismatch between these layers, combined with resonance avoidance, contributes to significant noise reduction. This principle ensures that the braking experience remains comfortable and noise-free, enhancing overall driving satisfaction.

Product Highlights

Our vibration damping and noise-reduction pads feature metal substrates available in thicknesses ranging from 0.2mm to 0.8mm and widths up to 1000mm. These substrates are coated with rubber layers of varying thicknesses, from 0.02mm to 0.12mm, offering single-sided and double-sided NBR rubber-coated options to cater to diverse customer needs. As a cost-effective alternative to imported materials, our products deliver superior vibration and noise-damping performance without compromising quality.

The material’s surface undergoes specialized anti-scratch treatment, ensuring high strength and resistance to scratches. Customers can choose from a range of surface colors, including red, blue, silver, and more, with guaranteed colorfastness. Additionally, we offer cloth-coated boards without textures, tailored to specific customer requirements, providing flexibility in design and application.
