Dustproof Rubber

Sealing Rubber   Shielding Rubberg

Dustproof rubber, which prevents foreign matter from adhering to the image sensor of a digital still camera or video camera, is produced in a clean environment.

  • High-Quality Dustproof Shield Components Are Produced in a Clean Environment.

    When fine foreign particles adhere to the CCD or CMOS image sensor of a digital still camera or video camera, the recording quality drops. This is why dustproof rubber components (sealing rubber, shielding rubber), despite their small size, play such an important role in improving image quality by preventing the entry of foreign particles. Yamauchi uses designs based on high-quality antistatic materials and advanced analytical simulation to provide your products with optimal dustproof rubber components.


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.
