Oil Coating Compression Molding Silicone Rubber Keypad

In the manufacturing process, we meticulously print symbols and graphics onto the surface of the rubber keypad. To enhance its durability and texture, we then apply a fine mist of protective oil, resulting in a smooth and matte finish. For keypads with silkscreen printed characters and symbols, we opt for an oil coating, while laser-etched

Oil Coating Compression Molding Silicone Rubber Keypad

Oil Coating Compression Molding Silicone Rubber Keypad

Oil Coating Silicone Keypads, also known as matte smooth silicone keyboards, provide essential surface protection. This protective oil cover safeguards rubber keypad surface symbols and characters against abrasion and scratches, extending the product’s lifespan. During manufacturing, symbols and graphics are printed on the rubber keypad’s surface. Following this, a fine mist of protective oil is sprayed on, resulting in a matte and smooth texture. Oil coating is commonly applied to keypads with silkscreen printed characters and symbols, while laser-etched silicone keypads are typically PU coated. This versatile approach ensures the durability and quality of silicone keypads.

Surface Protections Choices for Silicone Rubber Keypads

Besides oil coating, three other surface protection options exist: PU (polyurethane) coating, epoxy coating, and plastic keycaps. While oil coating is the most cost-effective, PU and epoxy coatings offer superior durability with their solid surface protection.

Both oil-coated and PU-coated silicone keypads feature matte surfaces. In contrast, epoxy-coated rubber keypads have a clear, attractive resin layer. Plastic keycaps, though effective, are pricier due to molding and labor costs.

These protective methods serve the shared purpose of prolonging keypad life, preserving icons and graphics, and maintaining silicone button colors.

Silicone Keypad Varieties Based on Graphic Processing Methods

  1. Backlit Keypads:

In illuminated keypads, characters or graphics are meticulously laser etched onto the silicone button surface. This precision process allows LED light to diffuse through the laser etched graphics, ensuring uniform illumination. Pantone colors and RAL colors are both available options for laser engraving, providing a wide range of design possibilities.


  1. Silkscreen Printed Silicone Buttons:

Silkscreen printing involves applying ink to the surface of silicone buttons, followed by a drying process. This method is commonly used for rubber keyboards. Both Pantone colors and RAL colors are applicable for creating vibrant and detailed designs on the silicone keypad surface.

We offer comprehensive keypad solutions and expert suggestions tailored to your specific design and production requirements, ensuring high-quality, customized silicone keypads for various applications.
