Laser-engraved silicone keypads are mainly applied in high-end industrial electrical and electronic communication fields. The advantages are clear printing, wear resistance, corrosion resistance and not easy to be damaged.
Laser Etched Keypad, is also known an Laser Cutting Keypad,Laser Engraving Keypad,adopted laser carving surface treatment to process by radium. Laser Etched Keypad is a type of silicone keypad. A lot of key manufacturers use laser carving technology to apply in products that are often used in mobile phones, electronic dictionaries, remote control,etc. Laser Etched Keypad make the product more beautiful and natural.
The sample lead time is 2-7 days, the delivery lead time is less than 15 days. Monthly production capacity is over 500,000 pieces. If the mold needs to be made, the time will be calculated by case

The difference between laser etched silicone keys and silk-printed silicone keys:
1. Laser etching is also called laser laser engraving, is one of the silicone button surface treatment technology, mainly used in car key, instrumentation and control panel key, is to use optical principle on the surface of silica gel key-press processing, make the silicone button surface need pattern of characters and symbols, and screen printing surface printing technology is adopted.
2. Touch the characters of the radium keys, there will be a concave feeling, while the characters of the screen printing keys have a convex feeling.But concave convex feeling is very weak, need to experience carefully.
3. If the back of the key with light source irradiation, screen printing key characters will not be transparent, laser etched silicone keys will be transparent background light source.
