Features of laser marking aluminum black

1. Adopting high quality light source, good spot quality, uniform optical power density, stable output optical power, which can realize precision processing.

2. the electric light conversion efficiency is very high, more than 30%, low cost, energy saving. The whole machine power is only 600W/h.

3. Scanning head built-in red light is used to preview the marking position, easier and more accurate to find the laser focus.

4. Auto focus function can be added to adjust the height of the laser focus according to the different heights of the products on the workbench.

5. Suntop fiber laser marking machine has passed strict aging test before leaving factory, 24 hours continuous output of laser beam to ensure 100% stability of the machine.

Details of laser marking aluminum black

1. Laser source

Using well-known brands of fiber lasers such as Raycus, MAX, and IPG, the performance is stable and the photoelectric conversion efficiency is high. There is no need to maintain the laser and beam transmission system, which can save a lot of maintenance costs and time.

2. High-speed galvanometer

High-precision laser scanning vibrating head, fast and clear, high stability.

3. High Lens Lens

The use of quartz high-transparency coating field lens greatly improves the light-gathering ability of the edge beam, high light transmittance, and good marking effect.

4. Control panel

Original JCZ EZCAD software and control card, USB interface, swift and stable transmission.

5. Professional software

The software system is powerful, and can optimize a variety of data according to different processes to meet the application process requirements of most industries in the market.

Advantages of laser marking aluminum black

● High contrast: After laser marking, black marks appear on the aluminum surface, which contrasts sharply with the natural color of aluminum, making the mark content clear and easy to read and improving the visual effect.

● Strong durability: The black mark after laser marking adheres firmly to the aluminum surface and is not easy to wear, fade or fall off, and has high durability.

● Anti-corrosion performance: The black laser marking layer can enhance the anti-oxidation and anti-corrosion properties of the aluminum surface, improving the durability and service life of the product.

● High precision: Laser marking technology has high precision and meticulous processing capabilities, which can achieve fine and clear black marks and is suitable for applications that require high-precision marking.

● Non-contact processing: Laser marking is a non-contact processing technology that will not damage the aluminum surface and maintain the original performance and appearance of the aluminum material.

● Efficient processing: Laser marking is easy and fast to operate, and has high work efficiency. It is suitable for mass production and rapid processing requirements, and improves production efficiency.

● Make customized products: They can be designed into different shapes, patterns or text as needed to realize personalized customized products and enhance the added value of the product.

● Environmental protection and energy saving: The laser marking process does not require the use of chemicals, produces no waste water, waste gas and chemical waste, and complies with environmental protection requirements.
