Laser marking machine has been used to mark products in many industries, and the mobile phone manufacturing industry is no exception. Today, I will take the iPhone, which is very familiar to everyone, as an example to explain the mobile phone laser pointer marking machine. From Apple 5, 5s, 6, recently released 8. Basically, every accessory of iphone products has the figure processed by laser marking machine.
For example, inside the iPhone 5 mobile phone case, IC and metal conductive bits, there are two-dimensional codes engraved with unique content to prevent imitation of counterfeit products. Then look at the black font of the manufacturer and the serial number area on the back of the Apple phone. At first glance, it looks similar to the ink. But in fact, it is neither ink coding nor silk screen printing. That’s right, this is also laser-treated. The shell of the Apple phone is alumina, commonly known as alumina black.
A mobile phone has green laser pointer marking everywhere, such as: Logo marking, mobile phone casing, mobile phone battery, mobile phone accessories marking, etc., and even inside the mobile phone that you cannot see, there are also laser marking of parts. The traditional method is to use screen printing to print on the surface. The silk screen printing ink is heavy, not delicate, difficult to follow, and the printing effect is not ideal. In addition, the ink used in screen printing is a heavy metal chemical element.
