SILICONE KEYPAD PARTNER
The silicone membrane keypad, also known as rubber membrane keypad or silicone rubber membrane keypad, is a type of keypad commonly found in electronic devices. Made from a flexible and durable material called elastomeric silicone rubber, these keypads are critical components in various devices such as remote controls, medical devices, and machinery. They are manufactured through either silicone keypad compression molding or liquid silicone rubber (LSR) injection molding processes. These keypads play an important role in providing tactile feedback and allowing users to operate electronic devices smoothly.
Manufacturing Steps
Material Preparation: Begin by getting the clear, stretchy silicone rubber material ready.
First Molding: Use compression molding to shape the silicone into the basic button pad.
Adding Color: Put on black and white coatings to make the buttons look good.
Laser Labeling: Use lasers to mark the buttons with letters or symbols accurately.
Printing Designs: Print detailed patterns or images on the buttons for a cool look.
Protective Coating: Put a tough polyurethane coating on the buttons to make them strong and smooth.
Extra Strength: Apply epoxy coating to make the buttons even tougher and last longer.
Smooth Finish: Trim off any rough edges or bits to make the buttons neat and tidy.
Sticky Backing: Stick on a special adhesive layer so you can easily attach the buttons to your devices.
Conductive Silicone Keypad Membrane:
Types: Silicone Button Membrane comes in two types: conductive and non-conductive.
Non-Conductive Type: These silicone membrane keypads don’t conduct electricity and are used as keycaps for electronics. They allow for backlighting either by placing LEDs underneath the silicone keypad or using methods such as laser etching.
Conductive Type: These silicone rubber keypads conduct electricity and use methods such as printing with conductive ink, carbon pills, metal domes, metal pills, and nickel pills under the keys. Different methods have different levels of resistance, so customers can choose the best one for their keypad needs. Conductive ink printing and carbon pills are popular choices for conductivity.
