laser engraving process

Laser engraving process

The laser engraving process is a new type of processing technology. Its main principle is to mark the surface of the material with a laser beam, thereby forming high-precision patterns and characters on the surface of the material. The use of laser engraving technology can effectively improve processing speed, precision and quality.

Laser engraving is widely used in major industries

3C digital/5G products

All electronic components marking, circuit board QR code marking, laptop keyboard marking, photography light logo marking, mobile power logo marking, cell phone components marking, memory card cover marking.

Auto parts/hardware marking

Automotive die-casting parts marking, hardware tools marking, automotive lamp marking, equipment parts components, bearing circle marking, precision drill bit marking.

Medical Devices/Precision Instruments

Scalpel markers, surgical forceps markers, medical instrument valve markers, weight markers, equipment catheter markers, precision instrument markers, and instrument work markers.

Jewelry/gifts/others

Hand jewelry markers, ring markers, portable steel decanter markers, watch markers, high-end fountain pen markers, thermos cup markers, wooden crafts, paper crafts, etc.

Container/Packaging Industry

Food packaging marking, pharmaceutical packaging marking, electronic packaging marking, etc. Applicable to various products and materials packaging.

Laser Engraving Applications
Laser Engraving Applications

The following is a typical process flow for metal marking using the laser engraving process:

  1. Material preparation: Prepare the metal material to be processed, determine whether its surface is flat and smooth, and polish it to make the surface smoothness as high as Ra0. 2μm, so as to ensure the quality and precision of the final laser engraving effect.
  2. Design pattern: Design the pattern that needs to be marked, convert it into G code, and output it to the laser engraving equipment controller, so as to realize automatic control.
  3. Adjust parameters: According to the process requirements, set the relevant parameters of the laser engraving equipment, including laser power, beam diameter, scanning speed, etc. Different materials and patterns need to set different parameters to achieve the best laser engraving effect.
  4. Processing laser engraving: use laser engraving equipment for processing, scan the laser beam along the designed outline, and engrave text, patterns, etc. on the metal surface by marking.
  5. Quality inspection: Carry out quality inspection on the processed parts to determine whether they are qualified or not, and record relevant parameters.

The typical process flow is as above, and the following is an example of a set of specific data: using laser engraving technology to mark the surface of stainless steel, the processing pattern includes text and patterns, the size is 50x50mm, the required character height is 0.8mm, and the resolution reaches 500dpi. In terms of equipment parameter settings, the laser power is 20W, the beam diameter is 0.02mm, and the scanning speed is 12000mm/s.

After the above-mentioned technological process is completed, the final laser engraving effect meets the requirements, with high character definition, perfect pattern, and smooth outline.
