Certification standards
ISO 9001, ISO/TS 16949, ASTM D2000, SAE J200, and RoHS are worldwide quality management system standards used in a variety of industries. ISO 9001 assures that manufacturers follow effective methods, whereas ISO/TS 16949 requires automotive parts to fulfill stringent quality standards. ASTM D2000 and SAE J200 provide unified rubber product classification and standardization techniques. RoHS Directive standards must be met by rearview mirror rubber cushions.
What is Rearview Mirror Rubber Cushion
A rearview mirror rubber cushion is a piece of rubber that is used to cushion and absorb vibrations and noise caused by the rearview mirror while driving. It is usually found at the bottom of the mirror bracket, where it comes into touch with the car body. The cushion absorbs energy from road vibration, wind resistance, and bumps, which reduces mirror shaking and provides a more steady driving experience. It is made of a tough rubber material that can handle pressure and vibration while providing a long service life. It also protects the mirror from direct touch with the metal surface between the mirror and the body, reducing scratches, scuffs, and corrosion. Overall, rearview mirror rubber cushions improve driving comfort and safety.
Advantage of Rearview Mirror Rubber Cushion
Rearview mirror rubber cushions are designed to reduce the impact of shock and vibration on the rearview mirror, providing cushioning and shock absorption. They absorb energy from road surfaces, wind resistance, and bumps, ensuring a stable position. This reduces vibration, providing stable vision and increased driving safety. The cushion also reduces noise and vibration by absorbing vibration energy, reducing transmission. It also protects the mirror and car body by preventing direct metal contact, reducing scratches, wear, and corrosion. The cushion is typically made of durable rubber material, able to withstand pressure and vibration, have a long service life, and are not prone to deformation or loss of function.
