1. A Small Component That Improves NVH Performance

The plastic mirror sound insulation pad is installed between the side mirror base and the door sheet metal. Although small, it plays an important role in improving vehicle NVH performance.

If this pad is missing or damaged, air leakage and wind noise may occur around the side mirror area. In addition, it helps prevent direct contact between the mirror base and metal surface, reducing the risk of paint scratches and wear.

Our factory has 14 years of experience manufacturing this type of component. We operate a 3,000 m² workshop with 35 skilled workers specializing in injection molding and precision parts production.

We use PP material, which offers good aging resistance, stable performance, and odor-free characteristics suitable for automotive interior and exterior applications.

2. Effective Sealing and Noise Reduction Performance

The pad is produced through molding or precision cutting processes depending on design requirements.

Available thickness options include 3 mm, 5 mm, and 10 mm, with 3 mm and 5 mm being the most commonly used specifications.

We focus strongly on vibration damping, wind noise reduction, and sealing performance. The pad helps prevent air, water, and dust from entering through the side mirror mounting area, improving overall cabin comfort.

High material density combined with strong adhesive backing ensures secure installation and long-term stability. The product is designed not to loosen or fall off during service life.

3. Long-Term Durability and Reliable Quality Control

The material is designed to maintain flexibility and stability over long-term use, without hardening, cracking, or powdering over time.

Our factory is certified to IATF 16949, and we implement strict quality control procedures throughout production. Each product is fully inspected before shipment.

We offer free standard samples (shipping cost borne by customer). The minimum order quantity (MOQ) is 1,000 pieces, with at least 300 pieces per size. Our monthly production capacity ranges from 1 to 3 million pieces, ensuring stable supply.

If you have any technical or customization requirements, our engineering team is available to support you.
