Spraying laser engraving is the most common production process for controller silicone buttons, for the following reasons.
1. Silicone key manufacturers say that most of the controller keys used on mechanical equipment have LED light beads at the bottom, and the surface of the keys needs to have light transmission requirements, and the light transmission of the spray laser engraving process is the best.
2. The spraying laser engraving process is more advanced. The spraying process can make an ordinary silicone key into a high-end key with good texture and feel. The laser engraving process can make the characters have a bumpy feeling and permanent wear resistance. The overall performance has been greatly improved in an instant.
