Laser Engraving
Considerations
Laser Engraving
- Suitable for crisp geometric textures and automotive decorative parts.
- Produces clearer, sharper edges than film exposure.
- Processing is slower and more costly.
- The mold requires high initial machining accuracy and repairs are more involved.

Technical Comparison
| Process | Suitable Textures | Considerations |
|---|---|---|
| Sandblasting | Fine EDM-like textures | Produces an even tactile surface. Scratch resistance and production life require review, and parting lines need careful protection. Processing is comparatively straightforward and efficient. |
| Film Exposure | Regular patterns with protected mirror-finish areas | Photoresist thickness, washing and repeat exposure require careful control. The resulting surface offers comparatively good scratch resistance. |
| Coated Texturing | EDM-like and larger dot textures | Provides longer service life and better scratch resistance than basic sandblasted textures. Local texture damage can be repaired comparatively efficiently. |
| Film Transfer | Leather-like and multilayer automotive textures for instrument panels, door panels and similar components | Multiple layers create depth and visual continuity. Repeated etching can affect parting lines, so an appropriate processing margin is recommended. |
| Laser Engraving | Crisp geometric textures for automotive decorative parts | Produces clearer, sharper edges than film exposure, but processing is slower and more costly. The mold requires high initial machining accuracy and repairs are more involved. |
