Introduire

A hood rubber cushion bumper is a shock-absorbing rubber cushion that is typically placed at the connection point between a car’s hood and body. Its primary role is reducing noise and vibration caused when the hood is closed, by absorbing and dissipating energy generated from road vibration, wind resistance, and bumps during driving. By doing so, it enables a reduction in the potential for collision and friction between the hood and the body, which prevents hood damage, noise, and vibration. This rubber cushion is typically made from durable rubber and has good elasticity and longevity. It can withstand pressure and vibration, providing long-lasting protection against direct contact between metal surfaces on the hood and body. This reduces the risk of scratches, scuffs, and corrosion, improving both appearance and protection.

Données techniques

Norme de certification

• ISO/TS 16949: ISO/TS 16949 is the automotive industry’s quality management system standard, developed to ensure that suppliers satisfy the quality criteria and standards of automobile manufacturers. Hood Rubber Cushion Bumper manufacturers may need to gain ISO/TS 16949 certification to demonstrate that their quality management system satisfies industry standards.
• ASTM standards: The American Society for Testing and Materials (ASTM) has created a number of standards relating to the qualities of rubber products and test techniques. Hood Rubber Cushion Bumper manufacturers may refer to standards such as ASTM D2000 (Standard for Rubber goods) to guarantee that their goods’ material properties, physical properties, and chemical properties fulfill specifications.
• Reach and RoHS directives: Manufacturers of such seals selling on the EU market may need to guarantee that their products meet the criteria of the Reach and RoHS directives. The RoHS directive prohibits the use of hazardous compounds in electronic and electrical equipment, while the reach directive restricts the use of chemical substances.
• Specific car manufacturers frequently have their own standards and requirements that vendors must achieve in order to become their certified supplier. Product manufacturers may be obliged to meet the specifications of a specific vehicle manufacturer and gain permission or certification from them.

Avantages et fonctions

1. Cushioning and shock absorption: The hood rubber cushion bumper cushions and absorbs shock at the mounting locations of the car hood. When the hood is closed, it absorbs energy from road vibrations, wind resistance, and bumps, decreasing vibration and noise. This improves ride comfort while also reducing impact on the hood and body.
2. Protect the hood and body: The rubber bumper serves as a barrier between the hood and the body. It prevents noise, vibration, and hood damage by reducing collision and friction between the hood and the body. Simultaneously, it can reduce direct contact between metal surfaces, lowering the likelihood of scratches, wear, and corrosion.
3. Noise and vibration reduction: The Hood Rubber Cushion Bumper reduces noise and vibration when the hood is closed. It has the ability to absorb and disperse vibration energy, reduce noise and vibration communicated to the automobile, improve the driving experience, and lessen the impact on other vehicle components.
4. Longevity and Durability: This rubber bumper is typically made of a robust rubber substance that has good flexibility and durability. It has a long service life and can handle pressure and vibration from long-term operation and varied climatic conditions.
5. Simple Installation and Maintenance: The Hood Rubber Cushion Bumper is simple to install and replace, requiring no special equipment or knowledge. This makes car repair and maintenance easier and more efficient.
