Laser marking plastic discoloration in the material

Publish Time: Aug. 18, 2022

【Description】:

Plastics absorb laser light. The color pigments (from additives, colors etc.) and carbon in plastics are destroyed and vaporize as a result of localized heating. A color change becomes visible and the frothing of the material can be felt.

With its laser advantage of 355nm short-wavelength cold laser, the UV laser marking machine mainly forms discoloration by breaking the plastic chemical molecular bonds on the plastic surface, without damaging the plastic surface.


Laser marking plastic discoloration in the material

Ultraviolet laser marking machine can currently meet most of the needs of the industry: such as product date, batch number, brand, serial number, two-dimensional code and other signs, once sprayed, can not be changed, play a greater role in anti-counterfeiting, prevent illegal manufacturers from organic Can take advantage of, protect brand rights.

 

CX-10Z adopts imported high-quality UV laser light source, which has higher absorption rate of UV light on non-ferrous plastics, and better photosensitive reaction discoloration effect. .


Laser marking plastic discoloration in the material

【Fine coding, clear and beautiful】


It has a wide range of applications, and can carry out fine marking, fine cutting, micro processing, etc. on most materials. The laser marking is fine and beautiful, and numbers, words, letters and characters can be accurately read. The photosensitive reaction has good discoloration effect, and the marking effect is more beautiful and clear.


【Code for high-speed flight】


It has the advantages of high-performance UV laser, high marking speed, good repeatability, short pulse width and high peak power to create high-precision marking quality. It can meet the dynamic coding of packaging and printing items on the line with a transmission speed of 0 to 150 m/min. The speed can reach the production capacity of 8 to 32 alphanumeric characters on the product package and 10000 to 40000 PCS/hour, which is suitable for high-speed continuous production lines.


【Environmental protection, energy saving, no pollution】


The UV flying laser color-changing coding machine adopts laser cold processing, which can directly interrupt and destroy the molecular structure of the material surface, resulting in a series of physical and chemical reactions, and the thermal effect is very small. It will not produce volatile substances such as peculiar smell, smoke and dust, and achieve environmental protection, energy saving and no pollution.


【Anti-vandal, no damage】


The laser-coded content cannot be destroyed by acid, alkali, solvent, high temperature, low temperature, etc., and has strong anti-counterfeiting and anti-destructive properties.


【No consumables, easy to operate】


The photoelectric conversion efficiency is high, the service life is long, and there are no later consumables, the equipment is easy to operate, and it works stably for a long time, meeting the needs of large-scale intelligent industrial production.
