Engraving
Engraving cuts text, numbers, scales and logos into a part's surface by CNC milling, laser engraving or chemical etching, producing deep, durable markings. It is used for dials, scales, nameplates, tools and moulds.
What it is
CNC engraving uses a small cutter to machine characters and graphics to a set depth, often filled with paint for contrast. Laser engraving removes material with the beam; chemical etching dissolves exposed areas through a mask for fine detail on plates.
Engraved marks survive painting, heavy wear and harsh environments better than surface marks.
Typical applications
- Nameplates and data plates
- Scales, dials and indicators
- Tool and die identification
- Mould cavity markings
- Control panel legends
Suitable materials
- Steel and stainless steel
- Aluminium and brass
- Tool steels
- Plastics and laminates
Points to consider
- Specify depth and font; small text limits cutter size.
- Paint filling improves readability.
- Chemical etching suits fine detail on plates in volume.
- Supply vector artwork for logos.
Frequently asked questions
What is engraving used for?
Durable identification and graphics such as nameplates, scales, dials and tool markings.
Is engraving deeper than laser marking?
Yes. Engraving removes material to a depth, while marking mostly changes surface colour.
Can engraved text be colour filled?
Yes. Paint filling engraved characters gives high contrast and readability.
