OEM rubber seal

Material

These custom components are made of EPDM (Ethylene‑Propylene‑Diene Monomer) rubber, a high‑performance synthetic elastomer. We adopt premium‑grade EPDM compound mixed in‑house, with adjustable hardness ranging from 40‑90 Shore A to satisfy diverse working‑condition requirements.

Key Features

• Outstanding resistance to ozone, ultraviolet rays, weathering and thermal aging, suitable for long‑term outdoor exposure.

• Excellent compression‑set resistance, maintaining stable elasticity even under long‑time compression load.

• Good shock‑absorbing and vibration‑damping performance; fine tolerance control for complex notched & stepped geometric profiles.

• Smooth black surface with sharp, clean edges, minimal flash and burrs from precision compression molding.

• Resistant to water, dilute acids and alkalis; stable physical performance within a wide operating temperature range.

Core Advantages

1. Superior weather durability: Resists cracking and performance degradation caused by sunlight and climate change, extending service life for outdoor‑used assemblies.

2. Reliable vibration & noise control: Effectively buffers impact, absorbs vibration and eliminates metal‑to‑metal abnormal rattling noise in mechanical and automotive assemblies.

3. High forming accuracy: Custom‑molded structure fits mating parts perfectly, playing stable roles in positioning, clamping and gap compensation.

4. Flexible customization: Formulation, hardness, dimension and shape can be tailored per customer drawings or samples.

5. Strict in‑house quality control: Raw‑material inspection, in‑process monitoring and finished‑part testing guarantee consistent batch‑to‑batch quality.

These custom‑molded EPDM rubber components are engineered for multi‑functional industrial and automotive applications.

Thanks to EPDM’s outstanding resistance to ozone, UV radiation, weathering and aging, these precision‑shaped rubber parts perform reliably under harsh outdoor and under‑hood operating conditions. Their special notched, multi‑step geometric profiles are designed for positioning, clamping, locating and gap filling.

They are widely adopted across multiple scenarios:

1. Automotive industry: Used for body assembly, chassis systems and interior‑exterior trim. They serve as positioning stoppers, cushioning buffers, anti‑rattle dampers and gap fillers to eliminate abnormal noise and absorb vibration between metal‑to‑metal mating parts.

2. General machinery & equipment: Act as locating blocks, anti‑shake pads and limiting bumpers for mechanical assemblies. They absorb impact energy, reduce mechanical vibration and prevent metal‑on‑metal collision and wear.

3. Construction hardware & electrical equipment: Applied as buffer spacers and shock‑absorbing locating inserts. They compensate for assembly tolerances, dampen vibration transmission and offer long‑term weather‑proof performance.

Customized according to customer drawings or physical samples, these EPDM molded parts can be tailored for specific installation space, load‑bearing requirements and environmental conditions. They effectively reduce equipment noise, extend component service life and stabilize overall assembly performance.
