Portable Laser Marking System features-Suntop

The UV laser marking machine uses a cold light processing mode with a fine spot size, enabling high-precision, permanent marking and engraving on non-metallic materials such as plastic, glass, and PCB circuit boards. The marked characters are clear and free of burrs, and the process does not burn or damage the surface of the workpiece, making it suitable for the fine processing of small items such as electronic components, plastic casings, and glass ornaments.


The equipment operates stably and supports long-term batch production on assembly lines. Available in 3W and 5W models, it can print various patterns and markings, including logos, serial numbers, QR codes, and parameter codes. With no consumables and low maintenance costs, the markings are abrasion-resistant and fade-proof, meeting long-term industrial traceability requirements.


The machine features a compact design and is easy to operate, making it suitable for integration with automated production lines. We offer free sample marking for testing and provide customized marking solutions tailored to various industries.

Advantages of Laser Marking

1. Cold processing that does not damage the base material: UV cold laser processing generates minimal heat, so plastics, glass, and PCBs will not burn, crack, or yellow, and the appearance of the workpiece is fully preserved.

2. Ultra-fine, high-precision marking: With an extremely small spot size, it can engrave tiny QR codes, precision characters, and intricate logos, meeting the micro-marking needs of small electronic components.

3. Wide range of non-metallic materials: Compatible with various plastics, tempered glass, PCBs, ceramics, resins, lenses, and other materials, offering a single machine for multiple applications.

4. Durable, fade-resistant markings: Laser etching penetrates the surface layer of the material, making it resistant to friction, alcohol wiping, and aging, ensuring markings remain clear even with long-term use.

5. Zero Consumables, Low Cost: Requires no ink, ink cartridges, or stickers—only electricity—significantly reducing operating costs for long-term, high-volume production.

6. Industrial-Grade Stability and Durability: The laser features a long service life, supports 24-hour continuous operation on assembly lines, has a low failure rate, and requires minimal maintenance.

7. Supports Automation Integration: The compact design facilitates easy integration with assembly lines and rotary fixtures, enabling fully automated batch marking.

8. Multiple Power Options: Available in 3W, 5W, and 10W models to accommodate both precision marking on small parts and large-area engraving.

FAQ

1. How can i place an order?
Please provide the details of your requirements as clear as possible. So we can send you the offer at the first time.
For further discussion, it is better to contact us with WhatsApp / WeChat / email / phone, in case of any delays.


2. What kind of display we provide?
We have laser marking machine / laser welding machine / laser cutting machine / laser cleaning / CO2 laser cutting and engraving machine / laser accessories for you choose.


3. How about the warranty?
We have 2 years warranty and lifelong maintenance.


4. What is your terms of delivery?
We accept EXW, FOB, CFR, CIF, DDU, DDP, etc. You can choose the one which is the most convenient or cost effective for you.


5. Why choose UV laser marking instead of fiber laser?

UV laser adopts cold processing technology with ultra-low heat radiation. It will not burn, yellow or crack the material surface. It delivers finer and clearer marking effects on plastic and glass, which fiber laser cannot achieve.


6. What is the marking precision of the UV laser machine?

The machine features ultra-fine laser spot, supporting micron-level precision marking. It can print tiny fonts, mini QR codes and delicate patterns, fully meeting high-precision processing requirements of electronic industry.


7. Will the laser marks fade or wear off?

UV laser marking forms permanent etching on the material surface. The marks are scratch-resistant, alcohol-washable and anti-aging, without fading or falling off for long-term use.


8. Is the machine easy to operate?

Equipped with intelligent control system, simple operation and fast parameter setting. New operators can get started quickly. It also supports automatic assembly line integration for mass production.


9. Does the machine require consumables?

No consumables needed. Only electric power is required, with low later maintenance cost, which greatly saves production cost for factories.


10. Do you provide free sample testing?

Yes. We offer free custom marking test according to your materials and patterns, and provide professional marking solutions for your business.
