Shanghai Xinyang precision mould, what is laser?

to be exact, it's called laser. Look at the mobile phone interface or notebook interface. There are many symbols. That is not sprayed with a paint brush. You must use a laser to carve. Adjust the laser intensity according to the material of the abrasive tool. For example, if you carve stainless steel with the laser intensity of aluminum alloy, the laser can't engrave it in a year. If you are going to work, you still need to wear radiation-proof glasses. You need to pay attention to the damage to the glasses. Don't worry about carving it on your hands.
