Preventing contamination in image sensors.

Dustproof Rubber

Seal rubber  Packing

Yamauchi provides dustproof rubber that prevents foreign particles from contaminating the imaging area of the automatic operation sensing camera, and dustproof and waterproof packing for the automotive backup camera.

Dustproof Rubber写真
  • High precision dustproof shield parts produced in our clean environment.

    The image quality of the automatic operation sensing camera greatly deteriorates with even just fine contamination on the imaging sensor (CCD, CMOS). In particular, since the camera on the back monitor installed outside the vehicle is constantly exposed to dust and rainwater, high quality dustproofing is required.
    In order to prevent the invasion of contaminants such as dust and water, Yamauchi utilizes original analytic techniques to optimize the shape design for seal performance and provides dustproof rubber (seal rubber, seal driver) produced in a thoroughly clean process. This plays an important role in improving the image quality of camera devices.


Quality control on production lines specialized in cleanliness for dustproof performance.

A clean environment is vital for the production of dustproof rubber. Yamauchi ensures its dustproof rubber is produced at the highest level of cleanliness in a quality controlled environment during all processes from rubber mixing to visual inspection.

Proposal of the optimal shape by shape simulation

Yamauchi can propose the optimal shape corresponding to the needs of each product by predicting the repulsive force and the sealing of dustproof rubber using analytic technology specialized for a non-linear model.

Implementation of fully automated visual inspection system

Yamauchi implemented automated visual inspection system with 2D, 3D camera to assure the superior quality of dust proof rubber parts for single or stereo type camera used for ADAS (Advanced driver-assistance systems) and operating picking, carrying, and packaging process by robot autonomously.
