Unlike with heat marks, where no material is displaced, laser engraving involves a process where the laser beam actually removes material from the part. The result can be a very shallow to very deep mark, and can be performed on almost all materials. Deep engraving can be achieved using high wattage lasers or multiple passes using a lower wattage laser.
What types of material can be laser engraved?
- Metals, plastics, ceramics, and organic materials can be engraved with a laser.
What types of laser sources are used for engraving?
- Fiber and YVO4 lasers can engrave on metals, some ceramics and hardened plastics.
- Green and UV lasers are best for semiconductors, silicon, ceramics, glass and some plastics.
- CO2 lasers are best for ceramics, glass, wood and other organic materials
What industries or applications use the engraving process?
- Laser engraving can be found in every industry including automotive, aerospace, electronics, firearms, oil and gas, packaging, heavy construction, and more.
- Deep engraving is beneficial for parts that will experience high wear or require after mark painting or coating.
