UV Laser marking of light- and dark-colored plastics

lastic laser marking offers several advantages over competing technologies like superior mark quality and lower cost of ownership.

Advantages include:

Permanence. With plastic laser marking, the material itself becomes the mark—improving the mark’s durability compared to ink marks or labels.

Quality. Lasers have high imaging resolution and can create line widths of only a few microns.

No consumables. Lasers avoid the consumables associated with other marking technologies. They also eliminate secondary processes like ink curing.

LASER MARKING METHODS

Because “plastic” encompasses a wide range of materials, various types of marks are possible, along with the lasers that produce them.

Our marking processes include:

Foaming. The most common method for marking dark plastics, this process expands the material at the surface to produce a bright color contrast.

Carbonization. The most common method for marking light plastics, this process “burns&rdq
