In the surface treatment process of silicone buttons, there is a technique that enables the patterns to "pop out on the buttons", giving the product a three-dimensional texture and a luxurious luster - this is the glue application process.
Soldering process
Dip molding is a processing technique where liquid resin is dripped onto the surface of a silicone key, and after curing, it forms a three-dimensional raised pattern. In simple terms, it is like "planting" a layer of transparent or colored crystals on the key surface, making the pattern become three-dimensional, full, and crystal-clear.
Dip coating process flow
Step 1: Net plate production - Create a net plate with a镂空 pattern for positioning
Step 2: Positioning printing - Print a containment wall in the area where glue needs to be applied to prevent resin from overflowing
Step 3： Glue application - Drop the resin onto the pattern area to form a hemispherical protrusion
Step 4: Solidification and shaping - The resin is heated in an oven or exposed to UV light to achieve solidification and final shaping.
Drip adhesive effect type
▶ Transparent glue: Reveals the underlying pattern, suitable for brand logos
▶ Colored glue: Resin has its own color, no need for underlying printing
▶ Glow-in-the-dark glue: Glows in the dark, suitable for products used at night
▶ Hardened adhesive: The surface is more durable, suitable for high-frequency contact keys
