What are the features of a handheld laser marking machine?

The handheld laser marking machine is a portable marking device that integrates a laser, a scanning mirror system, a control system and a power supply. Its core features are reflected in portability, flexibility, operation mode and application scope. 
High portability and flexibility
The main body of the device is of handheld design, with a small size and light weight. It breaks away from the limitations of traditional fixed optical path laser machines on the position and size of the workpiece. The operator can move the marking head to specific positions of large workpieces, assembled equipment or irregular curved surfaces for marking, achieving the operation mode of "device finding the workpiece". 
2. Simple operation, intuitive human-computer interaction
The equipment is usually equipped with a high-definition OLED touch screen. Users can directly set marking parameters, edit text or graphics on the handheld terminal. Some devices support wireless connection and can be remotely controlled via smartphones or tablets, reducing the operational barriers. 
3. Marking Accuracy and Speed
Using a galvanometer scanning system, the marking accuracy is quite high, typically reaching the millimeter level. The marking speed is determined jointly by the scanning speed of the galvanometer and the complexity of the marking content. For simple patterns and text, high-speed marking can be achieved. 
4. Wide material adaptability
Depending on the type of laser used (mainly fiber lasers and ultraviolet lasers), the range of materials that can be marked is extensive. 
Fiber laser handheld marking machine: Suitable for most metal materials (such as stainless steel, aluminum, copper) and some plastic products. The marking effect mainly consists of etching and oxidation color change. 
Ultraviolet laser handheld marking machine: Suitable for marking on heat-sensitive materials and highly reflective materials, such as glass, ceramics, ABS plastic, PCB boards, etc. The marking principle is "cold processing", enabling precise and stress-free marking. 
5. Long service life and low maintenance cost
The core components of the laser are semiconductor pump sources or fiber lasers. Their designed service life is long, typically reaching 100,000 hours. The overall structure of the equipment is compact, and there is no need for regular consumables. The daily maintenance cost is relatively low. 
6. Powerful software functions
The built-in or included marking software supports a variety of functions, including: automatic sequential number and date code marking; reading and marking barcodes and QR codes; importing vector graphic files such as DXF, PLT, and AI; and performing simple graphic drawing and text editing. 
7. Non-contact processing
The marking process involves a physical or chemical reaction between the laser beam and the material surface. There is no mechanical stress, and it does not cause compression deformation of the workpiece or wear of the tool. It is suitable for marking of precision components and soft materials. 
8. The Permanence and Anti-counterfeiting Feature of Markings
Laser marking is achieved by altering the structure of the surface material or removing part of the material. The resulting markings are permanent and are not easily worn or tampered with, thus having a high anti-counterfeiting capability. 
9. Energy conservation and environmental protection
The equipment operates with low power consumption, and the marking process does not produce consumables such as ink and chemical solvents, making it a clean and pollution-free processing method. 
The main features of the handheld laser marking machine can be summarized as being portable and flexible, intuitive to operate, having a wide range of applicable materials, leaving permanent and environmentally friendly marks, and having efficient software support. These features make it an effective supplement and alternative solution to fixed equipment in fields such as industrial identification, component traceability, and anti-counterfeiting.
