The Sealing Lens is a specialized rubber component engineered to fit the unique streamlined curvature of modern vehicle headlamps and taillights. Unlike standard flat gaskets, this product is precision-molded to match the exact 3D profile of your lighting design.
By ensuring a perfect gap-free fit, Kingtom's sealing lens protects internal electronic components and reflectors from oxidation and water damage, ensuring the longevity and safety of the vehicle's lighting system.

Kingtom Engineering Capabilities
★
Precision Mold Design: For sealing lenses, curvature is key. Our in-house tooling workshop ensures the mold matches your 3D drawing tolerances within ±0.05mm.
★
Rubber Mixing Technology: We customize rubber formulas to prevent "blooming" (white residue) which can affect the aesthetics of clear lamp lenses.
★
Mass Production Stability: Capable of handling Tier-1 automotive volume with consistent quality checks (CCD inspection available).
FAQ
Q: How do you ensure the rubber seal doesn't deform during installation?
A: We optimize the hardness (durometer) and cure rates of the rubber. Additionally, we can design anti-stretch backings or provide installation fixtures to ensure the seal maintains its shape along the lens curve.
Q: Do you perform aging tests on the materials?
A: Yes. Before mass production, we conduct rigorous accelerated aging tests (high/low temperature, UV exposure, and ozone testing) in our internal lab to ensure the seal lasts the vehicle's lifespan.
Q: What is the expected mold life for these parts?
A: Our high-quality steel molds typically support 300,000 to 500,000 shots. We perform regular maintenance and cleaning to ensure flash-free parts throughout the mold's lifecycle.
Q: Can you help if our current design is failing water leak tests?
A: Absolutely. Our engineering team can analyze your leakage points and suggest modifications to the gasket's cross-section or compression ratio to resolve sealing issues.
