In-vehicle lens housing with airtight sealing

Any device for vehicle requires high weather resistance. In case of vehicle mounted rear view monitors/cams, sealing structure with reliable weather resistant to protect camera system is required. Lens housings of the cameras we are supplying are a glass reinforced plastic case with geometric completeness for uniformed sealing pressure between lens and the case.

Even though some factors such as complex design and anisotropic material shrinkage caused deformation disturbing exact engaging of lens and housing, we applied precision compensation process with measurement and feedback for the molds, and then succeeded producing housings with better than 20 μm circularity.
