How do High-Quality DPSS Lasers print black letters and white letters on a white plastic case?

How does the laser marking machine for white plastic laser make black words and white words? The principle of the laser marking machine is to instantly vaporize the surface of the material through the high temperature generated by the laser focusing, and it is generally the color of the material itself. The color of laser marking mainly depends on the nature of the material, and secondly on the power of the laser (that is, the power, speed, spacing, and frequency). - Generally speaking, fiber laser marking machine can print white characters on metal, and metal laser marking can adjust various colors such as black and white, yellow, etc. When printing white, the parameters of laser marking need to be adjusted. Ordinary laser marking machines can only print gray or black-gray text information on aluminum products. The one that can make aluminum black is a special fiber laser marking machine.

Features of laser marking machine:

uv laser | green laser | Ultraviolet lasers | uv dpss laser | nanosecond laser | UV laser source | Solid State Lasers

1. It adopts an integrated overall structure, equipped with an automatic focusing system, and the operation process is user-friendly.

2. The electro-optical conversion efficiency is high, and the power consumption of the whole machine is less than 500W, which is 1/10 of that of the lamp-pumped solid-state laser marking machine, which greatly saves energy consumption.

3. Galvo type high-precision marking head, the marking effect is fine and can be processed repeatedly, and the marking speed is faster.

4. The marking software is powerful, compatible with files of Coreldraw, AutoCAD, Photoshop and other software; supports PLT, PCX, DXF, BMP, etc., and can be used directly

Automatic coding, printing serial number, batch number, date, barcode, QR code, automatic skip number, etc.

5. The laser beam is thin, the consumption of processing materials is small, the processing heat affected zone is small, the processing efficiency is high, and it is controlled by computer and easy to realize automation.

6. Strong environmental adaptability, can work continuously and normally in environments such as vibration, shock, dust, humidity, etc. It is easy to realize the coupling with the optical fiber, and can realize long-distance work.
