When it comes to choosing a marking technology for your parts, you have a lot of different options to choose from. One of the most popular technologies is laser marking. This process is effective for both product identification and traceability. In addition, laser marking can also be used for decorative purposes.

What is Color Laser Marking?

Color laser marking is a process that uses lasers to produce colored markings on parts. The color of the markings can be customized to match your specific needs. The markings can be used for identification and traceability purposes, as well as for decorative purposes.

How Does It Work?

The color laser marking process begins by using a laser to produce a black mark on the surface of the part. This mark is used as a guide for the coloring process. Next, a series of colored lasers are used to produce the markings on the part. The colors are chosen to match your specific needs.

The laser markings produced with this technology are permanent and highly accurate. The color of the marking is controlled by adjusting the wavelength of the laser beam. There is also no contact involved in this process, so there is no chance of physical damage to your parts.

Color Laser Marking on Plastics

When it comes to using color laser marking on plastics, there are a few things that you should know.

First of all, different types of plastics require the use of different wavelengths in order to produce markings. It is important for you to understand which wavelength is best suited for your chosen plastic-type. This will help you achieve the desired effect and avoid any damage to your parts.

In addition, you should be aware that the color of the markings may not be consistent from one part to the next. This is due to the fact that plastics are inherently variable in their composition. The best way to avoid this inconsistency is by using a calibration sheet. This will help you to ensure accuracy and consistency when marking your parts.

What About Colored Plastic Parts?

When it comes to color plastic parts, it is important to note that the color of the marking will not match the color of the part itself. The laser technology is only capable of producing black markings on plastics. When using this marking method for identification and traceability purposes, you should add a unique color code to your parts. This will help to ensure accurate identification.

Applicable materials for color marking plastic include:

Glass-filled plastics
ABS plastics
Polyethylene plastics among other plastics

Color Laser Marking on Metals

Color laser marking is also a popular choice for metal parts. When it comes to metals, there are a few things that you should keep in mind.

First of all, the color of the markings may not be consistent from one part to the next. This is due to the fact that metals are inherently variable in their composition. The best way to avoid this inconsistency is by using a calibration sheet. This will help you to ensure accuracy and consistency when marking your parts.

Moreover, lasers are capable of producing different types of marks on metal surfaces. These include subsurface damage, surface discoloration, subsurface discoloration, chemical etching, or color transformation. It is important for you to understand which type of mark is best suited for your specific application.
