Two-layer plastics, specially developed laser engraving materials, and certain metals such as anodized aluminum are particularly suitable for laser engraving. Two-layer plastics are especially common because removing the top layer creates a clear color contrast. It is important that the material is explicitly designed for laser processing, as not every plastic reacts in the same way.
Laser engraving works contact-free using focused energy, whereas mechanical engraving removes material with a milling tool.
Laser engraving is particularly suitable for:
- fine details
- small font sizes
- high production volumes
- fast processing
Mechanical CNC engraving is suitable for:
- greater engraving depths
- tactile markings
- certain metal applications
- specific contours or material requirements
Both processes have their place and are selected depending on the application.
For outdoor signage, materials must be UV-resistant, weather-resistant, and mechanically stable. Suitable materials include:
- UV-stabilized two-layer plastics
- multi-layer materials with enhanced weather resistance
- anodized aluminum
- stainless steel
Material selection depends on location, climatic exposure, and the desired service life.
Service life depends largely on the material used, the engraving technique, and the environmental conditions. High-quality two-layer plastics or engravable metals can remain legible for many years when properly processed, even under industrial stress.
Influencing factors include:
- UV radiation
- abrasion
- chemical exposure
- temperature fluctuations
- mechanical stress
A two-layer plastic consists of a thin top layer and a contrasting base layer. During engraving, the top layer is removed, revealing the underlying color. This creates a permanent, high-contrast marking. This material is frequently used for nameplates, control cabinet labeling, and industrial signs.
