We have independently developed a device that can continuously bond different materials online. It is capable of adhering at a speed of 1 shot per second (fastest) with an accuracy of ±0.1 mm (MIN). 【Applications】 It is used for bonding the main LCD panel fixing tape and dustproof cushions of mobile phones. *For more details, please contact us.

• Processing Contract

This is a processing method that wraps a conductive film around the core material without compromising its flexibility, using Otis's unique technology. It can be used in limited spaces for applications such as shield springs and contacts, demonstrating excellent conductivity. We can customize the material, thickness, length, and width freely to meet various customer needs. *For more details, please contact us.

• Processing Contract

To improve the brightness and contrast of the LCD, optical elastic resin (UV curing) or high transparency double-sided tape is used to fill the air gap between the cover panel and the LCD, or to bond the touch panel and the LCD. Our company has established an environment and equipment that allows for trial bonding with either method. Additionally, we have experience in building bonding lines for actual mass production, so please feel free to consult with us. *For more details, please contact us.*
