Laser Marking Machine Selection Guide
I. Fiber Laser Marking Machine (Primarily for Metals)
1. Marking Effects on Different Materials:
- Stainless Steel: Black, white, or color marking.
- Carbon Steel: Gray or black marking.
- Aluminum (Standard): White or gray marking.
- Anodized Aluminum: Black or white marking.
- Painted Metal Aluminum Sheets: White or gray marking.
- Copper (Red): Light purple marking.
- Brass (Yellow): White or light yellow marking.
- Galvanized Steel: White or black marking.
- Gold: Light yellow marking.
- Silver: Black or light white marking.
- Plastic Paint Removal: Exposes base color or creates transparent effects.
- Stone: Surface-breaking deep engraving (exposes base color).
- Laminated Wood: Surface-layer marking.
- Ceramics (Material-dependent): Varies by composition.
- Note: Suitable for some plastic parts with moderate marking requirements.
2. Key Configuration Points:

II. UV Laser Marking Machine (Primarily for Plastics, Leather, Glass, Jade)
1. Marking Effects on Different Materials:
- Plastics: White, gray, or black (material-dependent; samples recommended).
- Leather: White, black, or gray (material-dependent; samples recommended).
- Glass: Rough or satin finish.
- Jade: Rough texture, satin finish, or deep engraving.
