4x4 Translucent Silicone Button Keypad Manufacturer

Yuanyi is a manufacturer of a 4x4 translucent silicone button keypad. The 4x4 silicone rubber button keypad comprises 16 soft buttons arranged in a 4x4 grid and is generally made of transparent silicone material and molded. It is usually printed with conductive ink on the bottom and is compatible with 3mm or 5mm LEDs. When the button is pressed, the conductive circle contacts the printed circuit board to complete the circuit, providing a backlight effect for your musical instrument or electronic product. Our silicone button keypads can be used alone as backlit panels. Sometimes their surfaces are combined with an embossed polyester film layer to increase tactile response and achieve a better tactile feel.
 
We also provide customized services for your silicone button surface, including silk screen legend, laser etching, matte smooth coating, epoxy coating, PU coating, Plastic button cap, etc.

Production Process of 4x4 Translucent Silicone Button Keypad


Step One: Use the right materials


To use suitable specifications of silicone rubber materials, conductive ink, and vulcanizing agents. The right hardness is key to soft silicone keys.


Step 2: Molding


After preparing the correct specifications of the silicone rubber material, use a specific mold and compression molding process to start production. Temperature, pressure, and vulcanization time are crucial to the quality of the silicone buttons keypad.


Step 3: Secondary vulcanization (Optional)


After high-temperature vulcanization, the product undergoes secondary vulcanization to remove residues and improve performance. The product is usually placed in a vertical oven and baked at 180-200°C for 2-4 hours.


Step 4: Surface treatment (Optional)


To meet the performance or appearance requirements of some customers for the surface of silicone buttons, different processes or methods are usually used to process the product's surface, such as silk screen printing, spray laser engraving, PU coating, matte smooth coating, etc.


Step 5: Trimming


To make the silicone buttons perfect, the excess burrs of the silicone buttons are usually trimmed manually. This is sometimes done using a punch press.


Step 6: Final inspection, packaging


All products will eventually undergo random inspection by our quality department. Unqualified products will be scrapped directly. Qualified products will enter our finished product warehouse before packaging.
