Learn about laser engraving and laser marking machines
Laser technology has revolutionized manufacturing and product identification. Laser engraving and laser marking machines are two important tools used by various industries to create permanent marks on different materials, especially metals. While both machines use laser technology, there are clear differences between the two processes. Understanding these differences is critical for businesses and manufacturers to choose the right technology for their specific applications.
What is a laser engraving machine?
A laser engraver is a tool that uses a high-power laser beam to remove material from the surface of a material, creating a deep and permanent mark. This process is often used to create intricate designs, logos, serial numbers and other detailed markings on metal surfaces. Laser engraving is a subtractive process, which means it removes material to create the desired mark.
What is a laser marking machine?
Laser marking machines, on the other hand, are designed to create marks on the surface of materials without removing any material. Instead, it changes the surface of the material, creating contrasting marks. Laser marking is commonly used to add serial numbers, barcodes, QR codes and other identification marks to metal and other materials. The process is non-invasive and does not compromise the integrity of the material.
main difference
The main difference between laser engravers and laser markers is the depth and durability of the marks they create. Laser engraving creates deep, permanent marks by removing material, while laser marking creates surface marks without altering the integrity of the material. Additionally, laser engraving is great for creating intricate designs and decorative marks, while laser marking is better for adding functional identification marks.
Application areas
Laser engraving machines are commonly used in industries such as jewelry manufacturing, trophy and prize manufacturing, and custom signage production. Capable of deep, detailed engraving, these machines are ideal for adding personalized designs to metal products.
On the other hand, laser marking machines are widely used in automobile, aerospace, medical device manufacturing, electronics and other industries. These machines are used to add serial numbers, part numbers and other identifying marks to metal components and products.
Material
Another important factor to consider is the type of material each machine can process. Laser engraving machines are versatile and can be used on a variety of materials, including metal, plastic, wood, glass, and more. They are particularly suitable for decorative engraving on metal surfaces.
On the other hand, laser marking machines are specially designed for marking metal and some non-metallic materials. They are optimized to create high contrast marks on metal surfaces without causing any damage to the material.
Technology and craftsmanship
On the technical side, laser engravers typically use higher power lasers and run at slower speeds to remove material and create deep engravings. The process involves the physical removal of material through evaporation or melting, resulting in a permanent mark.
Laser marking machines, on the other hand, use lower power lasers and operate at faster speeds to create surface-level marks. The process involves changing the surface of the material through oxidation, annealing or foaming to create contrasting marks without affecting the structural integrity of the material.
in conclusion
In summary, while laser engravers and laser markers both utilize laser technology to create marks on metal and other materials, they serve different purposes and have different functions. Laser engraving is great for creating deep decorative engravings, while laser marking is better for adding functional identification marks. Understanding the differences between the two processes is critical for businesses to choose the right technology for their specific marking and engraving needs.
