With the application of ultraviolet laser is more and more close to life, it has a natural charm in the processing technology. Through the characteristics of short wavelength, narrow pulse width, fast speed, easy absorption of materials and high peak value, it has become one of the mainstream industrial lasers. UV laser technology continues to mature, processing technology has been widely used and popular. At present, the mainstream marking materials of ultraviolet lasers on the market are plastic, glass, ceramic and metal.
Ultraviolet laser and fiber laser thermal processing is the opposite, people usually call it."Cold"Processing, through the high energy density of the laser on the workpiece for local irradiation, so that the surface material gasification or color change of photochemical reaction, so as to achieve a permanent mark. Because UV laser marking has no consumables, and the marking effect is fine and beautiful, banning the traditional marking process has become an irreversible trend.
ultraviolet laser3C plastic marking
3C products are emerging in recent years with the development of the electronics industry, and in order to meet the higher aesthetic needs of modern people, the processing technology is becoming more and more precise. At the same time,In order to save production costs and a permanent mark, enterprises urgently need to find a new processing method, which has become an urgent need.UV laser marking temperature is low, fast, through the computer remote control, can achieve accurate marking. Due to the unique properties of ultraviolet laser, plastic marking will not cause deformation of the original due to high energy, and the phenomenon of yellow and black graphics and text.
Silver metal marking process
Know the circuit board friends know,Many parts of the PCB are made of precious metal materials, including gold, silver and copper. Small accessories like this, businesses in order to better distinguish, often add their own unique logo on the surface, and like the traditional inkjet or sandblasting marking technology, it is difficult to achieve such a fine process standard. UV laser output spot diameter is only 0.7mm, pulse width 15nm @ 30KHz, can achieve fine marking parameters.
Glass engraving
Glass technology is often contacted in daily life. It can be used for decoration, storage, decoration and so on. Now we often see some beautiful carving technology on cups. Without any color matching, it is still beautiful and picturesque. There is no need to worry about fading and pollution sources. At the same time, the speed of ultraviolet laser engraving is more refined than artificial engraving, the surface is smooth, the efficiency is higher, and the destruction in mass production is less.
Ultraviolet laser equipment can be used in many fields of flexible board production,IncludeFPC profile cutting, contour cutting, drilling, covering film window opening, soft and hard joint board uncovering and trimming, mobile phone shell cutting, PCB profile cutting and other processing fields.Laser marking of the handwriting clear light, can be marked out of black, white writing.
At present, UV laser technology is more mature in3-10W, widely used in various industries"Micro-Machining"In the field, it can be directly used for wafer cutting, ceramic cutting, film etching, laser marking, etc. Made in ChinaUnder the background of 2025's grand strategy, the traditional industrial manufacturing industry is facing a deep transformation. One of the directions is to improve the efficiency and turn to high-end precision machining with higher added value and higher technical barriers. The development of ultraviolet laser technology is fully in line with this trend.
Radium laser is a solid-state laser research and development, production, sales of laser accessories integrated manufacturers, after years of precipitation, UV laser powerFrom1W-5W is upgraded to 10W,15W or even 20W, which can meet the needs of different processing technologies in the market.A substantial increase in power, so that the processing performance doubled. And can achieve ultra-fine processing effect, such as no burning edge, no carbonization, thermal effect is small, and finally realize the requirements of modern technology.
