Laser marking machines can be integrated into production lines or operated as standalone devices, and they are controlled through computer software that allows for precise control over the marking process.
Overall, laser marking machines are versatile tools widely used in various industries, such as automotive, aerospace, electronics, medical, jewelry, and promotional item manufacturing, to achieve permanent, high-quality markings on a wide range of materials.

Advantages of laser marking ceramics

Ceramics is a complex and fragile inorganic non-metal. The marking of fragile products such as ceramics and glass has always been a very challenging task. Traditional marking of ceramics has always been a very restrictive technology, requiring a high level of experience in terms of tools, climate, and operators.
There are several advantages over traditional laser marking of ceramics:

  1. High-quality marking: Compared to conventional ceramic marking, laser marking of ceramics is more accurate. The laser beam can quickly leave a clear mark on the material's surface without damaging the ceramic's integrity.
  2. Versatility: Laser marked ceramics are highly versatile and can be used for complex designs on both glazed and unglazed ceramics. Make Logos, serial numbers, barcodes, etc., on the surface or the underside of the ceramic with minimal effort.
  3. Non-Contact marking: the laser head does not come into contact with the ceramic during the operation of the laser marking machine. This reduces the risk of material damage and ensures that the ceramic surface remains clean throughout the engraving process.
  4. High Precision and Accuracy: The special control system of the laser marking machine determines a more precise marking result. It is possible to mark very small fonts or complex designs on ceramics. Laser marking has a significant advantage over traditional engraving regarding clarity and accuracy.
  5. Speed and efficiency: laser marking machines are extremely fast and accurate. Laser marking of ceramics is highly productive and fast, making it ideal for use in small businesses.
  6. Personalization: laser marking makes creating many personalized and creative engravings on ceramics easy. The flexibility of individual markings and personalized messages can meet the needs of most customers.
  7. Wear and tear resistant: the marks left by laser marked ceramics are generally permanently preserved. Even the slightest friction in everyday life will not damage the engraving marks.
  8. Eco-Friendly and Non-Toxic: Laser marking is a clean and eco-friendly marking method. It does not involve the use of inks, solvents, or other chemicals typically associated with traditional marking methods. This makes it a safer and more environmentally friendly option.

Overall, laser marking ceramics provides a reliable, precise, and versatile solution for permanent marking on ceramic products. It offers numerous advantages in terms of quality, customization, speed, and durability, making it a preferred choice in various industries such as manufacturing, arts and crafts, and product branding.

Types of Laser marking ceramic

The following three methods are commonly used for laser marking of ceramics:

  1. Melting: The marking principle used when marking ceramics with infrared marking machines is to melt the ceramic. A fiber laser with sufficient energy at infrared wavelengths can easily melt ceramic materials. And this is also the preferred method for marking ceramics.
  2. Etching: Laser etching of ceramics makes obtaining high contrast etch marks easy.
  3. Absorption coating: This is an uncommon method of laser marking ceramics. Primarily, an absorbing material is applied to the ceramic surface. When the absorbing wavelengths interact with the coating material, the laser energy is absorbed into the coating material. This produces a contrast in color with sharp colors.

The process of laser marking ceramics

Laser marking on ceramic is a process that uses a laser beam to create permanent marks or patterns on ceramic surfaces. It is a popular method for adding serial numbers, barcodes, logos, or decorative designs to ceramic products. The laser beam interacts with the ceramic material, causing localized heating and vaporization, which creates the desired mark.
Here's a general overview of the laser marking process for ceramics:

  1. Preparation: Clean the ceramic surface to remove any dirt, dust, or oils that could interfere with the marking process.
  2. Choose the right laser system: Different types of lasers can be used for ceramic marking, such as CO2 lasers or fiber lasers. The selection depends on factors like the desired marking speed, precision, and the type of ceramic being marked.
  3. Adjust laser settings: Set the laser parameters based on the specific characteristics of the ceramic material, such as its composition, color, and surface finish. This includes adjusting the laser power, marking speed, and focus.
  4. Marking design: Prepare the design or pattern you want to mark on the ceramic surface using appropriate software. This can include text, graphics, or codes like barcodes or QR codes.
  5. Positioning: Align the ceramic item properly on the marking platform or fixture to ensure accurate marking placement.
  6. Laser marking: Activate the laser system and direct the laser beam onto the ceramic surface according to the desired design. The laser beam will remove or change the color of the ceramic material in the marked areas.
  7. Quality inspection: After marking, visually inspect the marked area to ensure the quality.

Notes on Laser Marking of Ceramics

A hard and fragile material such as ceramic requires us to use some techniques in the marking process to give a better marking result.

  1. Laser: fiber and CO2 lasers are recommended as they are more likely to leave deep marking marks on ceramics.
  2. Laser power: the higher the power, the clearer the marking marks.
  3. Marking speed: the speed should be manageable speed when marking ceramics. Otherwise, it will be difficult to leave a clear marking mark.
