In the realm of industrial marking and engraving, two prominent technologies have emerged as frontrunners: dot peen marking machines and 50W fiber laser deep engraving machines. These technologies play a crucial role in various industries by leaving permanent marks on surfaces. 

Dot Peen Marking Machine: 

Dot peen marking is a mechanical process that creates marks through the controlled impact of a stylus onto the material's surface. This technology finds its applications in industries such as automotive, aerospace, and electronics. Dot peen marking machines offer several advantages, including:

  1. Serial Numbering: Dot peen machines are used to mark serial numbers on parts for traceability and quality control.

  2. Component Identification: They are employed to engrave part numbers and identification codes on components.

  3. Barcodes and Data Matrix Codes: Dot peen technology is capable of marking barcodes and 2D data matrix codes for efficient tracking.


  1. Cost-Effective: Dot peen machines are generally more affordable than laser engraving systems.

  2. Durable Marks: The marks produced are relatively deep and durable, ensuring long-lasting visibility.

  3. Low Maintenance: These machines have fewer complex components, leading to lower maintenance requirements.


  1. Limited Graphics: Dot peen machines are not well-suited for intricate graphics or images.

  2. Noise and Vibration: The mechanical impact can result in noise and vibration during the marking process.

  3. Lower Marking Resolution,contents are hard to be identified.

Fiber Laser Deep Engraving Machine: 

Fiber laser deep engraving is a non-contact process that uses a high-powered laser beam to vaporize or ablate material from the surface, leaving behind permanent marks. This technology is mainly applied to metals due to its precision and versatility.

  1. Firearm Engraving: The 50w fiber laser deep engraving machine for metal is used for intricate designs and serial numbering on firearm components.

  2. Industrial Components: Deep engraving is used for branding, part numbers, and aesthetic markings on various industrial components.


  1. High Precision: 50W 100W fiber laser deep engraving machine on metal exceptional precision, allowing for intricate designs and fine details.

  2. Versatility: The non-contact process is suitable for various metals, including steel, aluminum, and titanium.

  3. No Direct Contact: Since no physical impact is involved, there's no risk of deformation or mechanical stress on the material.

Advantages over Dot Peen Marking:

  1. Intricate Graphics: Laser engraving can reproduce complex graphics, logos, and images with high accuracy.

  2. Speed: Laser engraving is generally 10X faster, especially for intricate designs.

  3. Non-Destructive: The non-contact nature of laser engraving ensures minimal risk of damaging delicate components.
