Laser color marking is meaningful to stainless steel

Introduction:Laser marking is becoming more and more common in life,beverage bottles,animal ear tags,auto parts QR codes,3C electronic markings,and more.Marking black is the most common,but many people do not know that the laser can also mark color patterns.


In 1999,Ann Marie Carey undertook a preliminary attempt at laser color marking on a bowl,making laser color marking of metal handicrafts and jewelry practical.


The laser color marking makes the pattern more diversified.The marked object bids farewell to the monochromatic color,the color depth is enhanced,the image is vivid,and the quality of the product is improved.It is an innovation to traditional craftsmanship.Since then, the scope of application of laser color marking has been continuously expanding,and it has also become a new type of technological means to increase the added value of products.


Stainless steel under the action of a laser heat source generates colored oxide on the surface,or generates a colorless and transparent oxide film,and presents various colors due to the thin film interference effect of light,which is the basic principle of stainless steel color marking, simple That is to say,under the action of the laser,the stainless steel surface produces a laser thermal effect. The laser energy is different,and the stainless steel surface also shows different colors.


The traditional stainless steel color preparation methods such as chemical coloring and electrochemical coloring used previously have high energy consumption,large pollution, and difficulty in achieving fine coloration.In contrast,stainless steel laser color marking has unique advantages.


1.Laser marking is green and pollution-free;


2,Marking speed, marking patterns can be permanently retained;


3,laser marking can be arbitrary editing a variety of text patterns, easy to operate.


In the endless application of colorful stainless steel in the fields of architecture, automobiles, arts and crafts,laser color marking provides people with a new and efficient solution to add a new color to stainless steel products,which is to increase the added value of the products.
