At present, in the laser welding machine industry, there are many manufacturers using stainless steel laser welding machines to weld stainless steel materials, so what is the effect of using stainless steel laser welding machines? The welding seam effect is very good. For example, many commonly used 304 stainless steel materials use laser welding machines. Compared with traditional welding, low-power pulse laser welding machine has the advantages of high power density, concentrated energy, small heat input, narrow welding seam, small deformation, small spot after laser focusing, accurate positioning, etc., which makes laser seam welding It is more suitable for welding small metal parts. Laser welding of ultra-thin stainless steel materials, because the material is thin, the perforation is easy to vaporize, and a continuous, non-burn-through weld must be obtained. The point is to control the parameters more precisely. Because of its extremely small thermal conductivity, stainless steel is only about one-third of that of ordinary low-carbon steel. It is less stressed during welding. Therefore, uneven stress and strain will be generated when local heating and cooling are performed. Longitudinal shrinkage produces a certain amount of pressure on its outer edge, and excessive pressure will cause its deformation, which not only affects the appearance, but also affects the quality of the steel plate. In addition, problems such as overburning and wear will occur. Welding current, pulse width, pulse frequency, etc. are the main parameters that affect the quality of laser welding, and their effects are as follows: One: With the increase of current, the width of the welding seam gradually increases, splashes gradually appear during the welding process, and the surface of the welding seam appears oxidized and rough. Two: As the pulse width increases, both methods can get the same result. The change of pulse width has a great influence on the effect of laser welding of ultra-thin stainless steel plates. A slight increase in the pulse width will cause the sample to oxidize and burn through. Three: As the pulse frequency increases, the overlap rate of the solder joints increases, and the width of the solder joints first increases, and then basically remains unchanged; through observation, it becomes more and more smooth and beautiful. However, when the pulse frequency increases to a certain value, the weld spatter is serious, the weld joint becomes rough, and the upper and lower surfaces of the weldment are oxidized. Four: The positive defocusing method should be adopted for laser welding of ultra-thin plates. With the same defocusing amount, the surface of the plate obtained by positive defocusing laser welding is smoother and more beautiful than the negative defocusing surface. Using a high-energy laser beam, a stainless steel laser welding machine locally heats the welding area to melt the material to achieve the purpose of welding. The advantages of this welding method are: non-contact welding, welding more flexible; high welding efficiency and fast speed ; Good welding effect, narrow range, small deformation; easy to realize automatic welding, and beginners can start working after simple training.

A comprehensive analysis shows that with the changes in the economic environment, the competition among metal laser cutting machine brands and manufacturers has become increasingly fierce, mainly in brand, price, channel, service and other aspects of competition. Among these factors, the price of metal laser cutting machine is the most important and most sensitive factor. So, what is the price of laser cutting machine? 1. The price of metal laser cutting machine is affected by production and transaction costs. The larger the production scale, the lower the production cost, but in fact, in the laser cutting machine industry, the production cost difference caused by the production scale is not big, because the expansion of the production scale can bring the low price advantage of mass production and procurement. , But it also brings a rise in management costs. And to some extent, production costs cannot be compressed indefinitely. At present, the homogeneity of laser cutting equipment is serious. Excessive squeezing of production costs leads to reduced distribution and quality degradation, and shoddy products are used as good ones. This situation is no longer a novelty in the laser cutting machine market. Therefore, if you want to increase the brand premium, you must also start from other aspects. In addition, another cost is transaction costs, including various taxes and fees in the course of business operations, as well as laser cutting machine logistics and public relations costs. The former is related to national policies and the level of logistics development, while the latter is related to the development level of the laser cutting machine market. Because the laser cutting machine industry has entered the buyer's market in recent years, linking transactions through some unconventional means has become a hidden rule in the industry, and changes in public relations costs will affect the price of metal laser cutting machines. 2. The price of laser cutting machine is affected by information asymmetry. The greater the price fluctuation of the metal laser cutting machine, the more asymmetric information. In the laser cutting machine industry, information asymmetry used to be an important reason for huge profits. It has not only the objective conditions of social communication and communication technology, but also the subjective reasons that manufacturers have artificially restricted the circulation of information in various regional markets in the industry. As the degree of market informatization continues to deepen, the problem of information asymmetry is gradually solved, making the price of the laser cutting machine and its accessories basically transparent. And because of the promotion of media tools such as the Internet, brand recognition (non-customer recognition) has become very simple. Eliminating information asymmetry and expanding visibility can start from different sales channels of laser cutting machines. 3. The price of metal laser cutting machine is affected by the profit of manufacturers and distributors. The interests of manufacturers and distributors are unified and opposite. Both companies have to make money, cooperation can continue, and the brand can penetrate into various fields and regional markets, and become bigger and stronger; but at the same time, the product quality and brand image are fixed for a certain period of time, and the price is also limited. Within a limited price range, without various costs, the profit is certain. I have too much, you have too little. In order to ensure their respective interests, both parties have a bottom line of profit. Below this bottom line, it may not be possible to reach an agreement. Therefore, the price will be limited by the bottom line of profits of manufacturers and distributors. If the bottom line of profit is high, the price will be high; if the bottom line of profit is high, the price will be high; If the bottom line is low, the price will decrease. The conflict of interests between manufacturers and distributors is often not simply reflected in the price of metal laser cutting machines, but in the form of brands that are mixed with cost-effectiveness. For example, at a price of 2,000 yuan, Apple and Xiaomi, one makes consumers feel a little cheaper, and the other is a little more expensive. Customers will make different choices for the same price. In the same way, for metal laser cutting machines of different brands and the same price, customers will also make different choices according to their actual needs and economic conditions. This machine can also adjust the product and price of this machine in the middle and low-end according to the different requirements of users and customer requirements, according to different grades, to meet the needs of users.

From "contaminated milk powder" to "problematic vaccines", "cross-border trafficking of counterfeit drugs" to "network sales of counterfeit drugs," food and drug safety issues continue to challenge consumers' nerves. It has special significance for the anti-counterfeiting, safety and traceability of drugs. According to the statistics of the Ministry of Commerce, the total sales of pharmaceutical products in my country in 2019 reached 1661.3 billion yuan, of which the sales of pharmaceutical products dominated, accounting for 74.2% of the total sales of the seven categories. It can be seen that the rigid demand of society has continuously expanded the scale of China's pharmaceutical market, but the subsequent drug safety issues are not uncommon and have aroused people's attention. In the process of research and development, production, circulation, and use of drugs, strict requirements and specifications are required for them to play a normal role. Among these materials, information such as production date, production batch number, main ingredients, scope of application, shelf life and other information is an important basis for anti-counterfeiting and anti-counterfeiting and traceability of drugs. The laser marking machine can print a variety of characters, symbols, patterns, etc. The size of the marking machine can range from millimeters to micrometers, which has special significance for the anti-counterfeiting and safety of medicines. Laser marking is a marking method that uses high-energy-density lasers to irradiate locally to evaporate or discolor the material, thereby leaving a permanent mark. The current applications of laser marking machines in the pharmaceutical industry are mainly concentrated in two aspects: Labeling of drug packaging Pharmaceutical packaging materials refer to materials that meet product packaging requirements, such as the production of packaging containers, packaging and bagging, packaging and printing, and packaging and transportation. The packaging materials have different uses and properties. The pharmaceutical industry pays attention to safety and health, and has high requirements for product labeling. Conventional packaging materials use printing technology. Before packaging, the drug information is printed with packaging materials before packaging. However, printing technology uses printing as the main method, and printing uses volatile substances, the quality is difficult to guarantee, and contains chemical residues; in addition, the volatile substances used in printing allow criminals to take advantage of opportunities, and it is difficult to track them. source. Moreover, laser marking is a non-contact and pollution-free marking method, which can not only meet the use of multiple packaging materials, but also can easily erase or invert all the information marked on pharmaceutical packaging materials. It is anti-counterfeit and ensures circulation. The traceability of drug information in, as long as there is a problem in one link, the relevant code can be used to find the source of the problem. Information sign of the drug itself This technology can perform laser marking on metals, plastics, wood and other materials, and its scope has been extended to the medical field. Mark the specifications and models on the medicine to make it a part of the medicine itself. For example, capsule marking. The previous marking method for the medicine capsules we eat is the imprinting method, which is the imprinting method directly on the capsule. Although this imprinting method is not many, it has direct harm to the human body. Using laser marking technology, it is possible to engrave, portray, etc. on drug capsules, effectively preventing drug contamination. At the same time, the laser marking machine does not require any material consumption compared with the traditional marking machine, and the printed medicine has no toxic side effects. All in all, the laser marking machine provides anti-counterfeiting labels and information storage for medicines, ensuring the safety of medicines, and saving ink and other raw materials for manufacturers. The laser technology of the laser marking machine helps medicines to be traced safely. By 2020, my country's pharmaceutical distribution industry will achieve transformation, upgrading and innovative development. Network + business model and cross-border integration will become an important means of drug safety traceability. In addition, network + laser technology uses big data as an important means to improve drug safety. Due to the laser marking technology for marking medicines, it has stable reliability and durability. The marking information is clear and intuitive, with strong anti-strike force, and it is not easy to be altered and erased, which guarantees the anti-counterfeiting of medicines. Economically, laser sign technology can greatly improve work efficiency, not only saving manpower and material resources, but also saving manpower and material resources. With the help of "Internet +", the combination of big data and cloud computing, as long as the use of drug label information, Internet technology can be used to query the production, circulation, and use of drugs. Make up for the shortcomings of the pharmaceutical distribution industry in the supply of public products and services. For example, the quality and safety of the circulation links, the supply of rural and border areas, the supply of low-value consumables and small varieties, the reserve of emergency medicines and medical equipment for post-disaster epidemic prevention, and the improvement of medical service capabilities.
