Application potential and income of ultraviolet laser marking machine

In recent years, the application of laser processing technology has become more and more popular. People from all walks of life have more or less access to laser. The production efficiency, profit and processing quality of laser have been recognized, which makes laser processing technology innovative and progressive. With the requirements of precision parts for high-precision processing, it is likely to appear in non-metallic materials, such as plastic, glass, fabric fibers, etc. In the future, the application of ultraviolet laser marking machine has huge market potential.

Ultraviolet laser marking machine

The ultraviolet laser is 355 nm wave band. The use of third-order intracavity frequency doubling technology can greatly reduce the mechanical deformation of materials, and the processing advantage of the heat affected zone is small. Fine processing is preferred. It is mainly used for micro cutting, marking and engraving of ultra-fine processing, especially for micro hole marking of food and drug packaging materials, marking/cross cutting of circuit boards, glass materials, and micro cutting of silicon wafers and other complex applications. In order to achieve high-end fine processing, the nanosecond ultraviolet laser currently used has a higher cost performance than the ultrashort pulse laser. Therefore, the ultraviolet laser with good processing effect has been rapidly promoted and applied in the past few years.

The industrial application of ultraviolet laser has developed from 1-5 watts in the early days to 3-20 watts now, and the most common application is in marking. In the marking of carton packaging, cable shell, colored plastic, polymer, semiconductor materials, etc., the effect is better in the production of UV laser, and the pattern is clearer. In recent years, as the state has strengthened the supervision of medical products and drugs, some domestic pharmaceutical companies have adopted laser labels, mainly to mark the date of origin of paper shells and bottle shells. More and more manufacturers also pay attention to the identification of circuit boards, mainly logos and two-dimensional codes. On the one hand, it is to prevent counterfeit products, and on the other hand, it is to achieve the traceability of product circulation.

In laser processing, marking code has developed into a mature process. No matter what materials are used to make patterns, it is easy to make patterns, but there are still some knowledge and some are not easy to achieve in order to play the desired effect. Therefore, new requirements are put forward for laser marking. In these laser processing applications, ultraviolet laser is the most appropriate. Therefore, once some process solutions are proposed, the demand for ultraviolet laser marking machines is very considerable.

What are the benefits of using ultraviolet laser marking machine?

1. Processing quantity and operation

Generally, the time for processing enterprises is not very fixed, that is, the time for processing is not very fixed. If the main business volume is sufficient, the enterprise can quickly recover costs. If the company recovers the cost slowly, some companies will only manufacture their own products, and the processing volume will decrease.

2. The machine needs to calculate the total cost

General machinery has a service life, just like automobiles have a scrapping life, the ultraviolet laser marking machine cannot be used all the time. The service life of ordinary marking machines is 4 to 6 years. Enterprises can calculate the difference between the cost and labor cost after using the UV marking machine and before using it, and then calculate the profit change after using it.

3. The marking machine shall meet its own needs

Not necessarily expensive fast UV marking machine is good, which needs to be judged according to your own needs. The power and cutting range of the machine are much better, and the price is also “expensive”. Enterprises can choose the ones that are suitable for them according to their actual processing needs, and do not have to choose expensive ones. Only those that are suitable for enterprises are the best.

As mentioned above, how much profit can the UV marking machine function bring to the enterprise or company? You need to calculate the quantity+machine cost+equipment from its function. The key is that when you have some customers, you can bring considerable profits.

How to select laser cutting machine manufacturers?

With the progress of domestic laser equipment technology, laser cutting machines are more and more widely used. There are three mainstream laser cutting machines: C02 laser cutting machine, fiber laser cutting machine, YAG laser cutting machine. Optical fiber laser cutting machine is the fastest processing machine among the three machines, and also the most cost-effective laser cutting machine. The optical fiber laser cutting machine can cut stainless steel plates and carbon plates within 16MM, with small gaps and good energy spot quality, and can be used for fine cutting. Compared with CO2 laser cutting machine, it has many advantages, such as high photoelectric conversion rate and low power consumption.

Although the fiber laser cutting machine has a high cost performance ratio, it is still very expensive at present (most of them are more than 200000 yuan, and the small power is basically more than 100000 yuan), but the cutting speed is very fast, such as the femtosecond punching technology. However, it is generally believed in the market that with the emergence of the fiber laser cutting machine 5000W and 10000 watt laser, the fiber laser cutting machine will eventually replace the high-power CO2 laser cutting machine, Therefore, most of the brands of optical fiber laser cutting machines in the market become more and more.

In recent years, the brand of optical fiber laser cutting machine has shown explosive growth. After the market competition heats up, users are also likely to be dazzled when purchasing, and do not know how to start.

When purchasing the brand of optical fiber laser cutting machine, it is necessary to consider the cost performance ratio, equipment quality, equipment stability and after-sales service level. Because for the laser cutting machine, such expensive and important equipment is easy to pay a heavy price if it is just greedy and cheap. Cheap prices may mean quality discounts or after-sales trouble. Therefore, choose the famous brand of optical fiber laser cutting machine as far as possible, and such after-sales service will be more guaranteed!

For the after-sales service of optical fiber laser cutting machine, generally speaking, the after-sales service speed of domestic optical fiber laser cutting machine brands is higher than that of foreign brands. And in terms of quality, after years of development, in the fierce competition and continuous breakthrough innovation, the brand price of domestic optical fiber laser cutting machine has been very high.

Geographic location is also important, because some brands only have local service outlets, while others have bases nationwide, so it is easier to ensure after-sales quality.

Of course, the larger the brand, the larger the customer base, the better the quality of service, and more service engineers can maintain and repair it. In addition, there are third-party companies that can provide after-sales service, while small brand companies are unlikely.

How to Select the Suitable Laser Cutting Machine

In the new year, no matter in terms of business growth or production quality improvement, enterprises should consider the following aspects when purchasing laser cutting machines in order to purchase equipment suitable for them.

1、 Scope of materials and business requirements to be handled

First, consider the business scope, the thickness of cutting materials, the thickness of cutting materials, the material of cutting materials, etc., and then determine the equipment power and the size of the workbench with the laser cutting machine manufacturer for procurement. Currently, the power of optical fiber laser cutting machines produced by Longtai Laser is 500W-6000W, and can be customized according to customer needs.

2、 Preliminary selection of laser cutting machine manufacturers

Once we have determined the production requirements of the enterprise, we can go to the manufacturer to understand the performance and basic parameters of the machine. According to the budget of the enterprise, select some companies with appropriate prices for communication and cutting samples for reference. Later, we can go to the manufacturer for field investigation, and have more detailed negotiations with the leaders of the laser cutting machine manufacturer about the machine price, after-sales training, payment methods, etc.

3、 Laser power

Among the factors determining the performance of the laser cutting machine, we should fully consider our own needs. The power of the laser is very important. For example, we often cut 6mm metal plates, so we choose 1500w-2000w laser cutting machines to meet the needs of production. If we cut more than 6mm materials, we need to consider higher power. The price of the laser is the largest part of the cost of the entire equipment, So whether a manufacturer is reliable depends on whether the laser power is sufficient. Longtai Laser uses Reyker laser, with visible quality and power redundancy design. It has been as new for three years.

Finally, we need to carefully study some important parts of the laser cutting machine when we purchase them. Specifically, laser cutting head, servo motor, guide rail, cold water box, whether made in China or imported, should be carefully compared with laser cutting machine manufacturers. These components directly affect the cutting speed and accuracy of the laser cutting machine. Some manufacturers may cheat customers by using domestic counterfeit imported accessories.

Laser cutting machine enables upgrading of traditional metal processing industry

With 5G technology, science and technology will continue to develop rapidly. Technological innovation has promoted the reform of many traditional industries and created many new industries. Today, Longtai Laser wants to talk to you about the cutting-edge means of industrial application – laser cutting machine.

According to the 2021 market research report, 70% of domestic enterprises engaged in metal processing and production have used laser cutting machines, which is superior to other metal processing equipment.

Why is laser cutting machine so popular in sheet metal processing enterprises? Because the cutting surface of the materials processed by laser equipment is smooth and flat, for example, the 3000W laser cutting machine is used, and no other adjustment is required after cutting. One time molding, this process greatly saves additional labor and processing costs, reduces various processing links, has high speed, high cost efficiency, and greatly improves the production efficiency.

The most widely used example of laser cutting machine is the design and manufacturing of automobiles, mainly including the cutting of body prototype parts, punching and cutting of sheet metal, which can be applied to the development and production of new automobiles.

For the processing of automobile parts, the traditional industrial equipment can only be produced by using molds in general. This set of molds can only be used for one type of workpiece, and the laser cutting machine can be used for high flexibility. No mold is needed. As long as there is a computer drawing, the workpiece can be flexibly cut from multiple angles and directions, which can effectively improve the processing efficiency and save the cost of opening the mold.

The laser cutting machine replaces the traditional processing method, reduces the mold investment, greatly shortens the development cycle of automobile manufacturers and parts suppliers, improves the processing efficiency and workpiece accuracy, and reduces the manufacturing cost.

This fully demonstrates the important role of the laser cutting machine in the traditional metal processing industry.

What is the flexible processing of optical fiber laser cutting machine?

The common word that most people use to evaluate the characteristics of optical fiber laser cutting machine is flexibility, so what is flexibility here?

On the surface, flexibility means that the production process is more flexible. This process is also called flexible processing. Flexible production means that different production tasks can be completed in production, market demand can be rapidly adjusted, and resources can be diversified.

The laser cutting machine is an important equipment for flexible and flexible production. The flexible and flexible processing of the optical fiber laser cutting machine refers to the multivariable processing combination process. The laser beam adopts direct and directional methods. The laser can rotate, tilt, move up and down, and can process the vertical surface of the workpiece and other complex workpiece surfaces; Flexible and flexible processing technology has high precision. Laser cutting uses moving or multi axis mode to rotate parts under the beam, which can deal with parts that are difficult to deal with by traditional methods. The laser head can move up and down freely, and the laser beam is controlled by the automatic focusing system, which can realize complex workpiece processing. As long as the mobile rotary workbench is used, various complex parts can be processed.

Therefore, metal optical fiber laser cutting machine can be used to process metal plates. No matter how complex the metal plates are, as long as you can draw graphics on the computer, you can achieve fine processing and production.

What are the advantages of the automatic edge searching function of the laser cutting machine?

As an important equipment in sheet metal processing enterprises, laser cutting machine is a complex system integrating light, machinery and electricity. Longtai Laser is also one of the manufacturers of this equipment. Longtai understands that laser cutting technology has attracted much attention among workers in the machinery industry. The new metal optical fiber laser cutting machine is more stable, safer and more efficient, which makes this equipment rapidly popular. Now, what are the highlights of an automatic edge searching technology mainly promoted by laser cutting machine manufacturers?

The automatic edge searching technology of laser cutting machine means that the cutting machine can automatically track and compensate the metal plates to ensure the processing accuracy. As we all know, the workpiece on the workbench sometimes weighs hundreds of kilograms, so the position of the plate cannot be adjusted easily. When the metal optical fiber laser cutting machine has the automatic edge searching function, it can save the time for adjusting the workpiece, improve the efficiency of the machine, and reflect the advantages of the laser cutting machine in terms of more, faster, better and less. After the laser cutting machine starts the automatic edge searching function, the cutting head can start from the specified point, then automatically measure several points on both sides of the plate, automatically calculate the inclination of the metal plate and the starting point of cutting, and perfectly complete the cutting task. For example, if the metal sheet is inclined on the workbench, direct cutting will cause waste, but when the laser head can sense the angle and edge of the sheet, the cutting process can adapt to the angle and position of the sheet to avoid waste of raw materials.

The automatic edge searching technology mainly promoted by laser cutting machine manufacturers brings the following advantages to enterprises:

1. Automatic edge finding is more accurate than manual calibration.

The traditional work piece correction requires manual adjustment, which wastes time and manpower. The error of the straightening tool cannot ensure that the final position is the most appropriate.

2. Automatic edge searching technology can save time and manpower.

Traditional calibration requires the operator to use lifting tools to move the metal heavy plate, and calculate the edge by measuring tools, so as to adjust the position of the workpiece in a short time, which wastes time and energy.

3. Automatic edge searching technology can be used to detect the angle of metal sheet, so as to adjust the cutting process to adapt to the angle and position of metal sheet and avoid waste.

Laser cutting machine manufacturers promote the use of automatic edge searching equipment, which solves the problem of low utilization rate of large and medium thick metal plates in processing.

With the continuous updating of science and technology, laser cutting machine manufacturers have changed from producing single functional equipment to producing multi-functional equipment, from a single industrial supply to the supply and satisfaction of multiple industrial production needs, and have continuously expanded the scope of market supply, so that the efficiency and quality of sheet metal processing and cutting have been rapidly improved to meet the needs of users.

Laser cutting machine manufacturer introduces how laser is produced

Many people have been exposed to such equipment as laser cutting machine, but to truly understand the working principle of laser cutting machine, in-depth research and learning are needed. Longtai Laser – The manufacturer of laser cutting machine will show you how to produce a laser generator today.

1、 How is laser generated?

Matter has an atomic structure. The electrons rotate around the nucleus. The orbits are different. These orbits are called energy levels. The electrons are in different energy levels, so are the atomic energies. Since the particles are at low energy level, the equilibrium state is that there are more low-energy particles than high-energy particles. If you provide an energy source, you can allow low-energy particles to absorb energy and jump to the high-energy level, so there are more high-energy particles than low-energy particles. This is called particle rank inversion.

High level particles have a tendency of spontaneous transition to low level particles. The electron spontaneously converts the energy level difference and releases a photon. The frequency of spontaneous emission, called spontaneous emission, is proportional to the energy level difference of the transformation. In accordance with the Planck formula, hve2-e1. h is the Planck constant, v is the frequency of the photon, and e1 and e2 are the high energy level and the low energy level, respectively. This photon also excites E2 particles, which are stimulated by the frequency, phase, direction and polarization direction of the photon, and are completely consistent with the radiation. At this point, the E2 level of a particle generates two identical photons, and then the E2 level of the particle is excited to generate four identical photons. This avalanche reaction enlarges the incident time and rapidly increases the light intensity. If two parallel reflectors are set at both ends of the radiation system to form an optical cavity parallel to the cavity axis, the light intensity is amplified before the two reflectors and becomes stronger and stronger until the e2 particles are stimulated to e1, the dramatic inversion of particles disappears and the light intensity does not increase.

In the process of reflection, with the change of the direction and wavelength of the resonance light, the resonance light cannot be formed and disappears outside the cavity at any time. With the same speed of light and high brightness monochromatic light, a “laser” is generated.

2、 Laser characteristics:

Brightness: It is the brighter light source in the world. The brightness of CO2 laser is 8 orders of magnitude higher than that of solar surface, and the brightness of nd glass laser is 16 orders of magnitude higher than that of solar surface.

Good directivity: near ideal parallel light, long distance propagation, small diffusion area.

Good monochromaticity: narrow spectral width. It is smaller than Krypton.

It has the characteristics of reflection, refraction, projection and focusing.

High power density; Generally, in 105-107W/cm2, it can reach 106-1012W/cm2 after full focus.

What are the brands of lasers

There are only a few brands of lasers, including imported IPG, Tongkuai discs, the best domestic Ruike, Chuangxin, and Ennai, which has entered the Chinese market in the past two years.

“Ruike Laser” is a national brand laser manufacturer in our country. If there is no Ruike, the Chinese are still buying lasers at a very high price. Once a 500 watt laser cutting machine of a certain brand was sold for more than 800000 yuan. At present, Longtai Laser 500W fiber laser cutting machine can be purchased for more than 120,000 yuan, so if there is no Ruike, industry giants like IPG will not reduce the price again and again, and even some good policies will not be open and authorized to our Chinese people.

Anyway, in the laser industry, because of the rise of Ruike Laser step by step, industry giants like IPG finally lowered their heads and made a series of concessions, so here we users should thank Ruike, a great company.

Analysis and comparison of advantages and disadvantages between laser cutting and traditional wire cutting

Laser cutting machine has been gradually recognized by the majority of users since its appearance. What are the disadvantages of traditional cutting methods and laser cutting machines?

Let’s first look at the difference between laser cutting and wire cutting:

Analysis of advantages of laser cutting machine:

The latest mainstream laser cutting equipment, mainly fiber laser cutting machine and CO2 laser cutting machine.

At present, CO2 laser cutting machine is mainly used for cutting and carving non-metallic materials.

The main advantages of laser cutting are: good cutting quality, high precision, fast speed and low processing cost.

Disadvantages of traditional wire cutting:

Wire cutting equipment can only handle conductive materials, which limits its scope of application and requires cutting coolant during the cutting process. For example, leather is not suitable for wire cutting. If the material is afraid of water and coolant pollution, wire cutting cannot be used.

In addition, according to the type of line used, common wire cutting is divided into fast line and slow line. When wire cutting is made of molybdenum wire, it can be used for repeated cutting. When the wire is cut slowly with ordinary wire, it can only be used once.

PS: Metal wire is used more than molybdenum wire because it is cheap.

Disadvantages of traditional wire cutting: wire cutting can also realize the processing of plates, but the cutting edge will be very rough, and the speed will be slow, which will cause serious environmental pollution.

After discussing the characteristics of laser cutting machine and traditional cutting equipment, the manufacturer will simply compare their cutting principles:

Working principle of the laser cutting machine: high temperature molten materials produced by high energy density laser beam irradiation are purged by high pressure gas. Therefore, the metal materials processed by laser cutting machine should not be too thick, otherwise the thermal shock zone may be too large to cut through.

Optical fiber laser cutting machine is widely used. It can cut most metal materials and is not limited by shape. Its disadvantage is that it can only cut relatively thin sheets.

Traditional wire cutting principle: molybdenum wire or metal wire cutting machine can produce high temperature to cut materials, usually used for mold processing. The more uniform the thermal shock zone is, the smaller it is. It can realize the cutting of thick plates, but the cutting speed is slow, only conductive materials can be cut, and the construction surface is small.

The disadvantage is that there are many consumables, the processing cost is higher than the laser cutting machine, and the environmental pollution is serious.

In a word, both have advantages and can complement each other. However, with the development of industrialization demand, the demand of processing enterprises for large-scale production is getting higher and higher, which means that the production demand of high efficiency, cutting speed, high quality and low cost needs more and more attention. The low cost laser cutting technology is more and more suitable for modern production needs, while wire cutting has gradually lost its market competitiveness.

With the development of technology, the price of laser cutting machine decreases due to the increase in the number of manufacturers. There are many metal plates, and the metal processing industry has chosen to upgrade the laser cutting machine in large part because the traditional cutting equipment can no longer meet the current processing needs.

How much can 15KW optical fiber laser cutting machine save cost and how low is its efficiency compared with 6KW?

With the gradual resumption of work and production in all walks of life, the pressure of enterprises in the manufacturing industry is also gradually increasing. In the case of insufficient staff, it is necessary to meet both the demand for orders before the year and the supply of new orders after the year. If you want to complete the production plan easily, you still need to work hard on the production tools.
Today, Longtai Laser, a manufacturer of optical fiber laser cutting machines, takes the processing of 10mm metal steel plates with large consumption as an example to see which one can save costs and deliver in time by selecting different optical fiber cutting machines.
As we all know, 10mm sheet metal is widely used in the internal parts of automobiles and transportation tools, as well as large mechanical equipment, such as the internal parts of excavators and cranes, so it is a typical sheet metal raw material.
If it is necessary to process 259200m 10mm carbon steel, it will take 122.7 days (nearly 4 months) to use 6000W optical fiber laser cutting machine, and only 30 days (i.e. 1 month) to use 15000W optical fiber laser cutting machine. The efficiency has been improved by 309%;
The processing cost is 108,786.24 yuan for 6000W optical fiber cutting machine and 44,634.24 yuan for 15,000W optical fiber cutting machine, reducing the cost by 59%!
Similarly, if it is necessary to process 259200m 10mm carbon steel, it will take 122.7 days (nearly 4 months) to use 6000W optical fiber laser cutting machine, and it will only take 30 days (i.e. 1 month) to use 15000W optical fiber laser cutting machine, improving the efficiency by 309%;
The processing cost is 108786.24 yuan for the use of 6000W optical fiber laser cutting machine and 44634.24 yuan for the use of 15000W optical fiber laser cutting machine, reducing the cost by 59%!
