Advanced Silicone Seal Rings for Lens Modules

This is a precision seal ring especially used in lens modules of the on‐vehicle camera modules. The camera is one of the key parts and keeps operating safely and steadily to play functions involved with driving safety, that is, vision. Since the function of vision involves long‐time test on road, the lenses suffer exposure from various harsh conditions when used in on‐vehicle vehicles, for example, sand and dust attacks, falling down at rainy snow weather, shaking vibration on bumpy roads, being moved by vehicle engine rooms at high temperature, and others. On condition of providing reliable waterproof and dustproof sealing effects, this seal ring can protect the lens itself from harm from the external conditions (sand and moisture), etc. Performance of the seal ring is directly related to image of on‐board vehicle image; it helps avoid equipment failure or camera malfunctioning due to entering harmful impurity in camera or shaking of the lens assembly by road shaking and helps increas…
