Laser marking uses the focused beam output from the laser to interact with the target object to be marked, thereby forming a high-quality permanent mark on the target object. The beam output from the laser is controlled by two mirrors mounted on a high-speed precision motor to realize the motion marking of the beam. Each mirror moves along a single axis. The movement speed of the motor is very fast, and the inertia is very small, so that it can realize the rapid marking of the target object. The light beam guided by the mirror is focused by the F-θ lens, and the focus is on the marked plane. When the focused beam interacts with the marked object, the object is “marked”. Except for the marked position, the other surfaces of the object remain unchanged.
Laser marking, as a modern precision processing method, has unparalleled advantages compared with traditional processing methods such as printing, mechanical scribing, and EDM. The laser marking machine has the performances of maintenance-free, high flexibility, and high reliability. It is especially suitable for fields with high requirements for fineness, depth and smoothness. Therefore, it is widely used in automation, pipelines, jewelry, molds, medical, food packaging and so on in various industries.
Automotive Industry
The development momentum of the automobile industry has spread to every household, and at the same time drives the development of automobile peripheral industries. Of course, with the development of science and technology, the application technology of automobiles is also improving. For example, laser marking technology has played a very important role in the production process of automobiles. Laser marking of tires, clutches, car buttons, etc. all demonstrate the important position of laser marking in the automotive industry.
The car keys marked by a laser marking machine give customers the feeling that they are the perfect combination of technology and mechanics. With the cooperation of the car’s luminosity, they will not worry about being worn and damaged if they find various buttons, because they can maintain very good marking shape.
The advantages of laser marking machines for auto parts are: fast, programmable, non-contact, and long-lasting.
In the field of automotive parts processing, laser marking machines are mainly used to mark information such as two-dimensional codes, bar codes, clear codes, production dates, serial numbers, logos, patterns, certification marks, and warning signs. It includes high-quality marking of many kinds of accessories such as automobile wheel arcs, exhaust pipes, engine blocks, pistons, crankshafts, sound translucent buttons, labels (nameplates) and so on.
Pipe Industry
Piping is a very important part of the building materials industry. Each pipeline has an identity code so that it can be inspected and tracked anytime and anywhere. The piping materials at each construction site are guaranteed to be authentic. This permanent identification requires optical fiber or UV laser marking machine to complete. Initially, most manufacturers used inkjet machines to mark on pipes, and now laser marking machines are gradually replacing inkjet printers.
The working principle of the printer is that the ink channel is controlled by the circuit. After charging and high-voltage deflection, the ink lines ejected from the nozzles form characters on the surface of the product. Consumables such as inks, solvents, and cleaning agents are required, and the use cost is high. It needs maintenance during use, pollutes the environment, and is not friendly to the environment.
The working principles of laser marking machines and inkjet printers are fundamentally different. The working principle of the laser marking machine is emitted by a laser light source. After the polarizer system burns on the product surface (physical and chemical reaction), it will leave traces. It has the characteristics of environmental protection, good anti-counterfeiting performance, non-tampering, no consumption, long use time, high cost performance, and cost saving. No harmful chemicals such as ink are involved in the use process.
Jewelry Industry
More and more people choose to personalize their jewelry through laser engraving. This provides designers and shops specializing in jewelry with a reason why they need to invest in this modern technology. Therefore, laser engraving is making a big push into the jewelry industry. It can engrave almost any type of metal and offers a variety of options. For example, wedding rings and engagement rings can be made more special by adding information, dates, or images that are meaningful to the buyer.
Laser engraving and laser marking can be used to engrave personal information and special dates on almost any metal jewelry. Using a laser marking system, you can add a unique design to any jewelry item for your customers, or add a serial number or other identifying mark so that the owner can verify the item for security purposes.
Laser engraving is a modern alternative to creating designs. Whether it’s engraving classical gold carvings, engraving rings, adding special inscriptions to watches, decorating necklaces, or engraving personalized bracelets, lasers provide you with opportunities to process countless shapes and materials. Using a laser machine can realize functional marking, pattern, texture, personalization and even photo engraving. It is a creative tool for the creative industry.
Laser provides clean and environmentally friendly technology, does not contain chemical substances and residues, does not come into contact with jewelry, and the engraving details are accurate, which is more durable than traditional engraving. Precise, accurate, sturdy and durable. It can provide non-contact, wear-resistant, permanent laser marking on almost any type of material, including gold, platinum, silver, brass, stainless steel, cemented carbide, copper, titanium, aluminum, and various alloys and plastics.
Mold Industry
In industrial production, the proportion of mold product output in the market has always occupied an important position. The identification information of hardware products mainly includes various characters, serial numbers, product numbers, barcodes, two-dimensional codes, production dates, product identification patterns, etc. In the past, most of them were processed by printing, mechanical scribing, and EDM. However, the use of these traditional processing methods for processing, to a certain extent, will cause the mechanical surface of the hardware product to squeeze, and may even cause the loss of identification information. Therefore, mold manufacturers have to find another way to improve product quality. With the development of laser technology, laser marking machines are making use of their excellent performance and quality to continuously expand the application range in the hardware mold industry.
The laser marking and engraving system is a fast and clean technology that is rapidly replacing the old laser technology and traditional engraving methods. Compared with traditional embossing or jet marking methods, fiber laser technology provides a variety of permanent laser marking and engraving methods, which can be used in many applications in the tool and mold and mold manufacturing industries. In addition, the text and graphics marked by laser are not only clear and accurate, but also cannot be erased or modified. It is very beneficial for product quality and channel tracking, effective expiration prevention, and product sales and anti-counterfeiting. Alphanumeric characters, graphics, logos, bar codes, etc. can be easily applied using laser marking machines, and are widely used in industrial markets and tool manufacturing. With the development of laser technology, laser marking machines have become more precise and useful, and are suitable for more and more various parts.
Medical Industry
The medical industry pays attention to safety and health, and has very high requirements on product marking. Therefore, the medical industry has used laser marking technology for many years. Brings great benefits to medical device companies. Since the spray marking method is often unusable because the paint contains toxic substances and environmental pollution, the best marking equipment is non-contact and pollution-free.
In the medical industry, laser marking has also become the preferred marking method because it ensures the high quality and precision of the marking, the reliability of the system and the excellent repeatability. Manufacturers in the medical field must strictly abide by the established process. Therefore, if the recognized marking template is modified, it must be recorded in detail. Manufacturers are in an advantageous position if they have equipment that can repeat accuracy with the help of a vision system.
The mainstream of the traditional marking method is ink printing, which uses gravure offset printing to impress pills. This method has low cost, but the ink and other consumables are consumed seriously, and the marks are easy to wear, which is not conducive to traceability and counterfeiting. Laser marking is a non-contact marking method that does not require consumables. The laser marking machine is used to mark stainless steel surgical and dental equipment and other medical equipment, which is easier to read. The marks after countless disinfection and cleaning are still clearly visible. And it can effectively prevent bacteria from sticking to the surface of the equipment. The importance of laser marking machines in the medical industry is increasing day by day. Many manufacturers have discovered the versatility, accuracy, and cost savings of laser marking.
Packaging Industry
In recent years, “food safety” has been a hot topic. Nowadays, people no longer only pay attention to packaging, taste, and price, but pay more attention to food safety, but what is less known is that food packaging on the market is mixed, and even the shelf life that people most believe can be faked. As an advanced laser processing equipment, the laser marking machine is applied to the food packaging industry, which will help to curb the “date game” on food packaging from the source.
An industry insider said: “Whether it is printing or inkjet printing, as long as the ink is used, it can be modified. The printing time information can be adjusted arbitrarily within three years.” For the problem of modifying the shelf life of food, from large enterprises to Most small vendors know it well. Only consumers are kept in the dark by “hidden rules”, which seriously infringes on the rights and interests of consumers.
Only use laser marking and laser “engrave” information such as the production date on the package. Laser marking is a marking method that uses a high-energy density laser to locally irradiate the workpiece to vaporize the surface material or produce a chemical reaction of color change, thereby leaving a permanent mark. It has high marking accuracy, high speed, and clear marking and other features.
The laser marking machine can print a large amount of data in a very small range. The laser can mark the product material itself with a very fine beam. The printing accuracy is extremely high, the control is accurate, and the printing content is clearly and perfectly interpreted. Market competitiveness, environmental protection and safety, without any corrosiveness, completely isolated from chemical pollution, is also a kind of intimate protection for operators, ensuring the cleanliness of the production site, reducing subsequent investment, and reducing noise pollution.
In the future, as the current laser technology continues to mature, laser marking technology is bound to be widely used in more and more fields.
