What is Laser Marking? & What is Laser Engraving?

Laser marking is a permanent process that uses a high energy density laser beam to irradiate the part, vaporize the surface material or change the color, so as to create a lasting mark on the surface. The common types of laser marking including engraving, annealing, carbon migration, discoloration, and etching. Laser marking can print all kinds of characters, symbols, patterns, etc. The process generally completed by fiber, pulsed, or continuous wave laser machine.

Laser engraving is a kind of laser marking method, which through lasers to engrave an object like CNC turned part.

The Advantages of Laser Marking Process - Laser Marking Benefits

1. Automation and High Speed

As the laser marking process can be automatically performed with high speed and high efficiency, once marking can be completed in seconds, we can save lots of times or deal with large amounts of products in a short period of time, applying different laser marking techniques according to different applications would be faster.

2. Cost-Effective

The efficient and automatic process can not only save time but also reduce costs. Operators only need to set up the laser marking machines to make them complete the work automatically, instead of handling the system manually, so it can cut lots of labor and operational cost, the main cost resource is the electricity consumption.

3. Precision and Lasting

Laser marking and engraving service can print extremely accurate and precise marks, characters and patterns on small turning parts. The marking is clearly shown on the surface and lasting permanently, and will not fade due to environmental influences such as touch, acid and reducing gas, high temperature, low temperature, etc.

4. No Damage & No Pollution

Laser marking is non-contact processing, which can print marks on any regular or irregular surface, and the workpiece will not generate internal stress after marking, so as to ensure the original accuracy of the workpiece and not cause damage to the material. In addition, the whole process is safe and environmental-friendly, no corrosion to the working surface, no wear, no poison, and no pollution.

5. Anti-counterfeiting

The marks engraved by laser marking technology are not easy to copy and change, can prevent forgery. 

6. Wide Application

Laser marking can process many kinds of metal and non-metal materials. 

Laser Marking Materials - What Can Be Processed By Laser Marking?

Laser marking machines can work with a collection of common or uncommon materials as below.

Metals: aluminum, anodized aluminum, steel, stainless steel, magnesium, chromium, precious metal, brass, copper, titanium 

Plastics: ABS, PMMA, PA, PBT, PC, PE, PES, PET, PI, POM, PP, PPS, PS, PUR, PVC
