Silkeypad Color Matching Capabilities
We use Pantone's globally standardized color system for matching the color of the rubber keypads themselves, or the color of any graphic artwork applied to them. In fact, extremely subtle color changes cannot be detected by the human eye, but Silkeypad exceeds industry standards and accurately matches each color to reduce chromatic aberration.
Silkeypad can mold not only opaque pigments but also translucent pigments. The amount of pigment injected into silicone rubber directly affects the clarity of the final product. We use advanced instruments to test the surface finish, transparency and color of the samples. These high-precision machines enable our technicians to efficiently analyze, formulate and control the color of liquid silicone keypads.
We can accurately match the pigments of molded parts with our high-quality silicone-based inks. Silicone-based inks form a permanent bond when applied to silicone rubber products. Silicone inks are mixed and metered to the nearest hundredth of a gram to ensure color accuracy and repeatability for silicone rubber buttons.
High-quality pigments, precision hardware, advanced software and experienced lab technicians help us match and manufacture colors on-site. This greatly improves the consistency and repeatability of our silicone buttons keypads while also speeding up color matching lead times.
Multi-Color Keyboard Production Methods
Silicone rubber can be easily matched to RAL and Pantone colors and can even be customized based on color samples provided by the customer. There are three main methods of producing this type of silicone rubber keypads:
Injection molding materials of different colors in the same mold
This is one of the most economical methods and is achieved by injecting different colors of silicone rubber simultaneously into the same mold. Although there may be some flow between different colors, this flow can be minimized by controlling the position of the rubber in the mold and controlling the weight of the colored material.
Pre-molded buttons in different colors
Ideal for designs that require clear connecting lines between the base keyboard color and different button colors. This method involves pre-molding colored buttons in separate button molds and then loading them into the main keyboard mold as a secondary operation.
Spray the button with the desired color
This method can be considered if the first two methods are not feasible. Silicone-based spray that can be matched to RAL and Pantone reference colors. Spray the buttons made of silicone rubber and use a mask made of silicone rubber to protect the unsprayed parts. This method is more expensive because spraying the keyboard is less efficient, especially if multiple colors need to be sprayed and the operation needs to be repeated.
