Skill Selection of Laser Code Maker

As companies increasingly focus on cost savings, environmental protection, and hope to improve Anti-Counterfeiting and anti-chain capabilities, people's eyes began to shift from traditional spray code technology to the latest laser code technology. More and more enterprises start to use laser to play(spray) machine. There are many types of lasers and many technologies are used. According to the type of laser generator, there are solid lasers, semiconductor lasers, CO2 lasers, and YAG lasers. Different lasers are suitable for different industries. In the field of packaging marking, CO2 laser is the most widely used. Here, we mainly discuss the realization and production of the current cooperation, the realization of online flight standard CO2 laser coding machine.

Most users have questions about how to choose a laser that suits their company. Here are some methods and tips.

First, understand the material of your existing product. Some materials do not absorb the energy of CO2 lasers, such as uncoated metal surfaces, PP, and so on. Different materials absorb lasers to different degrees. For example, PET absorbs laser energy far more easily than glass, that is, it is easier to print than glass. Therefore, different power lasers are used for products of different materials, while some products can not use lasers. Usually a color carton, PET, only needs a 10W laser machine. There are also those that persuade you to use 30W, which only shows that his 10W machine is not fast enough. And 30W machines are also more expensive than 10W machines. Glass and metal require more powerful lasers, such as 30W or even 50W.

Second, in the specific understanding of a brand of laser machine, to understand whether to use a metal closed laser tube. Because the current metal closed laser tube is the best sealing, no leakage. Ceramic tubes and glass tubes are less confined, easy to leak, and easy to break during transportation. Therefore, the laser tube of the metal tube should be selected when selecting the type.

Third, when examining the stability of the equipment, we must understand the service life of the laser tube, and even more understand the technology used by the factory to control the opening and closing of the laser tube. Because the laser is like a large light bulb, the more times it is turned on and closed, the more likely it is to break. Therefore, when choosing a type, try to use a laser with less than the number of times the laser tube is turned on and closed. There are currently two major technologies: dot matrix residence technology and underline technology. Both use a motor to drive two sets of lenses for X direction and y-direction rotation. However, the control technology for lasers is different. A set of 20-character data is also used. The laser machine using the dot matrix residence technology is only opened and closed once, while the laser machine using the underline technology is to open and close 20 times. One character opens and closes once. At present, Marken's Smartlase110i/130i series laser machine uses the United States-patented dot matrix residence technology.

Fourth, the longer the service life of the laser tube, this is the most common kind of misunderstanding. Think that the more power the more gas is filled, the slower it is consumed. In fact, the greater the power, the more heat the laser tube emits during operation. If it can not be effectively emitted in a timely manner, it will burn the laser tube. Therefore, equipment above 50 watts usually needs water cooling and has a large cooling system.. Therefore, the high wattage does not guarantee the service life of the laser tube. If the cooling system does not work well, it is more likely to burn, and it also increases the cost of heat dissipation. The less energy the laser machine produces, the less heat it generates, the easier it is to heat, and the stability of the device is better. 10W, 30W equipment can achieve natural air cooling, do not need external gas sources, such as Marken's Smartlase110i/130i series.

Choosing the most suitable laser is the first step to obtaining a satisfactory logo. We recommend that users can simply understand the basic knowledge of the selection before selecting the laser machine, and then together with your supplier, select the laser machine that is most suitable for the identified product.
