Marking of non-metal parts in the automotive sector
The non-metallic materials in the automotive industry are mostly black plastics, and the materials are relatively simple. The colors of the 1064nm end pump laser with high peak power are often whiter.
The contrast is clearer and the cost is lower; when the fiber laser is processing such originals, the color is often gray-black, the contrast is not good, and the scorching is very serious.
The pulse width of the end pump laser is 6 ~ 20ns, so it is low thermal effect and higher peak power.
Metal materials are very advantageous, although there is no way to change the UV optical device ratio, but the advantage of end pump compared to fiber laser
very obvious.
The fiber laser pulse width is too wide, the peak value is too low, it only has advantages in metal processing efficiency, but not for non-metal processing.
Application Context for Marking of non-metal parts in the automotive sector
UV and precision laser applications are sensitive to material absorption, thermal effect and edge quality. Before choosing a system, CNMarking normally evaluates the sample material, expected mark contrast and whether cutting, etching or surface marking is required.

How to Choose a Similar Marking Setup
Before selecting a machine, prepare a short sample brief with the following information. This helps CNMarking recommend the right laser, dot peen, scribe or automation configuration instead of only matching a picture.
- Material type such as glass, sapphire, plastic or coated surface
- Required line width, edge quality and visual contrast
- Fixture accuracy and camera positioning needs
- Batch size and inspection requirement

FAQ
Can CNMarking test my own samples before I choose a machine?
Yes. For most marking, cleaning and welding projects, sample testing is the fastest way to confirm contrast, depth, speed and fixture requirements before final configuration.
What information should I send for a quotation?
Please send the material, part size, marking or cleaning area, required result, production volume and any automation or traceability requirements. Photos or short videos of the current process are also helpful.
