As we all know, among all laser processing technologies, marking is the earliest application and the most widely used technology in the industry. Laser marking is a marking method that uses high-energy-density lasers to partially irradiate the workpiece, vaporize the surface material or cause a chemical reaction that changes color, thereby leaving a permanent mark. Laser marking can produce various texts, symbols, and patterns, and the character size can range from millimeters to micrometers, which is of special significance for product anti-counterfeiting and product traceability.
In my country, laser marking has occupied more than half of the laser processing market for a long time. Although the share has declined, it has exceeded 32%. In 2018, the output value of laser marking optical devices and equipment in my country exceeded 25 billion rmb.
The laser marking market is becoming high-end
Laser marking is the field with the lowest entry-level technical requirements and is the first choice for many companies to start, including Trumpf, Han's, and Huagong, which have not given up this business to this day. From the earlier lamp-pumped laser marking machines to CO2 laser, pulse fiber laser, and semiconductor laser marking, it has undergone many upgrades. The demand for marking machines is very large, but the competition is also quite fierce. With the sharp decline in the prices of CO2 lasers and pulse fiber lasers, the most common marking machines are only 10,000 to 20,000 yuan, which is completely a state of micro-profit. What is the way out and development direction for laser marking?
One way out for the development of laser marking lies in the development of technology and process, that is, flying marking, fast marking and three-dimensional marking, while improving the accuracy and pattern effect. Another way out is the diversification of applications. It is no longer limited to a few fields such as clothing, toys, and electronic manufacturing, but is increasingly being tried in non-metallic industries such as plastic products, handicrafts, food and medicine, PVC boards, PCB boards, bamboo products, luggage, and aviation, precision instruments and meters, auto parts, plumbing hardware industry, general machinery, and household appliances. Laser marking applications in these industries have become new growth points in the market. The high-end development of laser marking equipment is an inevitable trend of development.
CKLASER: The first super laser marking concept
Ordinary computers are familiar to us, but to handle some more complex calculations and scientific deductions, a powerful supercomputer is needed to calculate. It is a million times faster than ordinary desktop computers and naturally has strong computing power.
Super must be a powerful upgraded version of such products in terms of functions. According to market demand, Guangzhou CKLASER launched a super laser marking machine, which shocked the industry as soon as it was launched. CKLaser is the first company in China to propose the concept of super laser marking machine and is a design pioneer in this field. Its birth marks that the laser marking process has greatly improved to a higher level and broken the pattern of traditional laser marking.
CKLaser is one of the earliest companies in my country to engage in laser marking, and it is also the only company that specializes in marking equipment and technology so far. In recent years, CKLaser has led the industry in the development of high-end laser marking equipment, from simple two-dimensional marking to three-dimensional marking technology, and has developed a three-axis dynamic system to achieve high-speed marking, which is 40%-50% faster than other peers. CKLaser has already mastered a unique trick in the marking application of curved surfaces, inclined surfaces, high and low surfaces and irregular products.
CKLaser: Leading the new trend of laser marking
The super laser marking machine launched this time is the first in China, and there was no such concept in overseas countries before. So what is a super laser marking machine and what advantages does it have? What impact does it have on current marking applications?
The super laser marking machine mainly breaks through the current problems of slow speed, low precision, rough pattern, insufficient format of traditional marking machines, highlighting the three core advantages of ultra-fast, ultra-fine and ultra-large range, which will bring an innovative change to the traditional laser marking process.
The super marking machine expands its working range, with a marking format of 400-800mm, and uses laser powers including 180 watts, 250 watts and 350 watts. Adopting 3Dlaser's self-developed software control system, it is equipped with a three-axis control "3-axis" optical path system, which can realize the free change of focal length through three-axis lens offset; adopting a new generation of three-axis dynamic focus control technology, it perfectly solves the engraving problems of irregular surfaces such as curved surfaces, high and low surfaces, terraces, and special-shaped surfaces; dynamic focus large-format technology integrates marking and cutting capabilities, with a larger effective range, higher precision, and better uniformity.
This super marking machine of CKLaser can increase the marking speed by up to 30% through optimized optical systems, control systems and scanning heads. The beam quality of the metal laser is 1.2<M2, the power density is high, and the focus spot is 50% smaller in the same range, which can greatly improve the fineness of the pattern. The configuration system and working range can be selected from 400mm×400mm to 800mm×800mm, and the maximum effective marking range is 1600mm.
Super laser marking machine is very suitable for 3D curved surface engraving, 3D high and low curved surface engraving, leather engraving, large-format cloth engraving, 3D bevel engraving and other applications. The patterns produced are beautiful, more significant than ordinary marking machines, and the efficiency is greatly improved. The equipment can also be equipped with a mobile feeding system to realize assembly line marking operations.
