Color Coated Rubber Keypads
The OEM Silicone Button Color Coating Rubber Keypad, also known as a multi-color silicone keyboard, involves clear rubber keypads coated with various colored inks. This process creates vibrant and multi-colored keypads, perfect for backlighting applications. By laser-etching legends and graphics onto the colored surface, these keypads achieve precise and durable symbols that are ideal for various devices.
Advanced Coating Technique for Uneven Surfaces
For rubber keypads with uneven surfaces, traditional methods like silkscreen printing are inadequate for creating detailed graphics. Instead, the color painting method is employed. This involves applying different color layers sequentially onto the silicone keypad surface, followed by laser etching the desired symbols. This method ensures that the graphics are clear and distinct, even on irregular surfaces.
Detailed Coating Process
The process begins with applying the first color layer. For instance, to create a keyboard with a black background and white symbols, a white color layer is first sprayed onto the keypad surface. Next, a black coating is applied over the white layer. Finally, a laser is used to etch the surface, revealing the white symbols beneath the black coating. This multi-layered approach not only enhances the visual appeal but also ensures the durability of the symbols.
Ensuring Optimal Backlighting
When creating color-printed keypads, it’s essential to apply more than one layer of ink to avoid light leakage, especially for backlit keypads. A single layer of printing is insufficient for maintaining vibrant colors and preventing light from seeping through the keypad. Therefore, at least two layers of printing and coating are applied to ensure the colors remain bright and the keypad functions optimally under backlighting conditions.
Preventing Color Mixing
For rubber keypads with multi-colored buttons, preventing color mixing is crucial. One effective method is using additional key caps to cover unnecessary buttons during the coating process. This ensures that the color coating is applied only to the intended buttons, keeping them separate and preventing unwanted color blending. Once the coating process is complete, the key caps are removed, leaving the buttons with their designated colors intact.
By utilizing these advanced techniques, the OEM Silicone Button Color Coating Rubber Keypad delivers high-quality, multi-colored keypads that are both visually appealing and functional, making them an excellent choice for various applications.
