In today’s fast-paced manufacturing world, laser marking machines have become essential for industries requiring precision, durability, and efficiency in marking. These machines offer a non-contact, permanent marking solution, ensuring high-quality results across various materials. Whether for branding, identification, or regulatory compliance, laser marking technology is the go-to solution.
What is a Laser Marking Machine?
A laser marking machine is a device that uses a focused beam of light to create permanent marks on surfaces. This process alters the material’s properties or appearance without damaging it. The most common laser marking methods include:
• Annealing Marking – Used mainly for metals, producing high-contrast marks without affecting the material.
• Carbon Migration – Creates dark marks on metals by causing carbon to migrate to the surface.
• Foaming – Used for plastics, creating light-colored marks.
• Coloration – Produces different colors on certain materials, such as titanium and stainless steel.
• Engraving – Removes material to create deep, long-lasting marks.
