Laser Marking for Metal
How Laser Marking Works
Laser marking makes marks that stay on metal. The laser beam hits the metal and changes it. You can make words, numbers, logos, or codes. The process is quick and gives sharp marks. Laser machines can mark many items fast. You use a computer to control the laser. This helps you get the same mark every time. You can change settings for deep or light marks. Laser marking works on many metals. Some examples are aluminum, steel, stainless steel, anodized aluminum, magnesium, lead, zinc, and copper.
Pros and Cons
Laser marking gives clear and sharp marks. The marks last for many years. You do not need ink or chemicals. The process is clean and safe if you follow rules. You can mark many shapes and sizes. The laser does not touch the metal, so it does not hurt it. Laser marking is fast and saves time.
Tip: Always wear laser safety glasses when using laser marking.
You must follow safety rules. Here are some important steps:
- Use laser safety covers and locks.
- Put up laser warning signs.
