Precision punching and pressing of thin film materials that are prone to wrinkles and creases, such as dust-proof and waterproof mesh and metal foil. We specialize in fine and small-scale processing.
We process components for dust and water resistance in the microphone and speaker parts of smartphones and similar devices. By combining materials such as dust and water-resistant mesh, resin, cushioning, and double-sided tape through punching and bonding processes, we create products that consist of multiple layers of precision-engineered components. As the main product becomes more compact, the individual components are also being miniaturized and slimmed down. This requires precise processing of difficult-to-work-with materials, such as functional films, that are thin. Our company manufactures presses, molds, and jigs in-house, allowing us to customize equipment and flexibly respond to various processing conditions. Additionally, we have experience handling over 10,000 types of materials, including functional materials. If you are facing challenges with processing films, thin materials, or bonding and laminating different materials, please feel free to contact Oatis.
