The working principle of laser coding machine is to focus the laser on the surface of the marked object with high energy density, vaporize the substance on its surface through combustion and etching, and accurately burn out patterns or characters by controlling the effective displacement of the laser beam, thus leaving permanent marks. Laser marking can print all kinds of characters, symbols and patterns, and the size of characters can range from millimeters to microns, which is of special significance to the anti-counterfeiting of products.

Laser engraving can be roughly divided into three types.

Carving principle of laser inkjet printer

Advantages of laser inkjet printer:

The average trouble-free life of laser light source can reach 65,438+000,000 hours. The laser light source needs little maintenance and has no environmental pollution, which saves a lot of costs compared with traditional ink printing.

2. The laser logo never fades, and there are no problems such as unclear logo caused by the external environment, which enhances brand awareness.

3. It can be recognized in various styles such as QR code, barcode, picture and text.

4. Prevent date tampering and counterfeit and shoddy products.

5. Labor saving, no need to change ink from time to time, stable code spraying, and no influence on the normal operation of the production line.

The latest identification security traceability technology has been applied to the product identification and anti-counterfeiting fields in food and beverage, biomedicine, auto parts, bathroom products, cable pipes, building materials, electronics, aerospace, hardware tools and other industries, and the application experience in various industrial scenes has been mastered, and we are committed to providing users with stable and reliable products and services such as laser coding and visual inspection, and helping modern enterprises to continuously improve their product quality assurance capabilities.

20 17 Wuhan Cable No.2 Factory changed the ink into a laser inkjet printer.

Laser code spraying equipment is also constantly updated and iterated, which has increased a lot of convenience in the process of development. What we can intuitively feel is that

The red light is fixed in focus, so you don't need that ruler to measure the focal length.

Red light preview can preview the code spraying effect before laser code spraying, and it also saves a lot of unnecessary waste.

Early warning function to prevent spray leakage.

It can meet the requirements of laser code spraying on various curved surfaces.
