Such strong security of the effective protection of the interests of consumers, consumers will be able to have more confidence to buy the products.

Laser coding applications in the food packaging industry

Food safety is one of the focus has been in the national interest. In this era of rapid development towards well-off everyone inside. In the consumer goods industry, the packaging has been one aspect is of particular concern, food safety is a top priority, this is necessary in the application of laser coders talked about and value the food packaging industry, the current laser technology this aspect gives us a good solution, for example, when consumers buy puffed food, packaging bags seal is not good enough, it is easy to spill the contents of the package, in the period will be shortened aging, as well as some tight seal, along dotted line tear was hard, so it was in when you open the package is difficult to control the intensity of certain foods, the consumer's point of view these are the little things a headache, but laser system laser coders can do choose flexible packaging in a separate thin film layers crossed. Doing so easy to achieve the perfect flexible tear effect, and can maintain the integrity of the film, so that the outer layer of the film intact, so that we can see light and moisture effectively prevent the product packaging and other issues. On the other hand, the aluminum foil layer or other plating layer on the metal film, which became the leading laser blocking barrier layers of other materials. So the properties of these materials can be such that the laser technology can be accurately positioned on the packaging material, crossed. Meanwhile, the tear line through the human eye is clearly visible, so torn packaging for the consumer becomes a breeze. Laser scribing and laser drilling technology effectively prevents the expansion of pores and to avoid damage to the package integrity, and can also have good ventilation, moisturizing effect. We had to do was shocked laser coders amazing technology.

Laser Marking Machine Working Feature

                              Laser Marking Machine Working Feature

Laser marking machine is widely used thermal infrared light processing, below are the laser marking machine processing characteristics.

First, because the laser is thermal processing, laser beam instantaneous high temperature to form the imprint processing methods. So for some hardness and brittle frangible material, like the high melting point of the material and soft material products processing, there is no doubt that easy to marking. From the laser marker appears, the marking technology is more and more improved.

Second, it says the high heat of the laser beam, so the little natural high-calorie due to the high density of the laser. Then the processing speed is very fast, and rapid processing will reduce the need for post-processing, and due to the small heat-affected area, it is hard to find the state of deformation of the workpiece by eye.

Third, it can be said laser is invisible substance, so there is no contact, the replacement of worn tools, etc. will not happen, so unless there is a problem laser marking machine itself, or will not happen suddenly stopped working things , which is the modern high-efficiency production and processing of the general trend in production line.

Fourth, the laser beam is almost invisible with this tool is the use of a substance can be converted in each direction, to achieve a significant flexibility of the machine, so some items for processing complex is handy!

Fifth, whether it is with the new processing lines or traditional manual processing and can fit each other, the applicability of the above better than traditional tools.

Color Marking on Stainless steel

OFweek Laser News: With the development of application of laser technology, print a variety of eye-catching bright colors on stainless steel by laser, this application has been gradually coming into view. These seemingly ethereal fantasy colors, are there any regularity to track? How to adjust the parameters to get the desired color quickly? Is there any requirement on the application of the laser light source ?

Stainless steel color principle

The human eye is able to distinguish between a variety of different colors, in fact, because when the light shines on the surface, the reflected light of different wavelengths, these different wavelengths of light are captured visually cells through the brain processing resolution, it creates different colors feeling. This return to a stainless steel material, only after a laser treatment can be of various colors, the truth is the same.

From the physical properties of stainless steel to analyze the principles of color, stainless steels are nothing more than change before and after the laser processing in three ways: First, to form a colored oxide; the second is by chemically, electrochemically or laser role in generating a stainless steel surface colorless, transparent oxide film layer is extremely thin oxide film to produce an interference effect, the surface may show color; the third is at the same time there is a mixed state colored oxide and oxide film.

MOPA laser marking color on stainless steel

MOPA laser's advantage lies in its width and frequency independently adjustable, adjust one does not affect the other laser parameters, this is the Q-switch lasers are not available. The MOPA structure feature, the color marking for stainless steel with infinite possibilities. In actual operation, marking these factors pulse width, frequency, power, speed, fill mode, fill spacing, delay parameters will affect the color effects. The impact of these parameters will cause a color change feature is not unique, but are interrelated and influence each other.

Have mentioned before, pulse width and frequency are characteristic MOPA lasers, mutually independently adjustable; and, these two parameters in stainless steel color play on two parameters is also the most distinctive, mutual cooperation between them, can be adjusted a colorful world. Today, the protagonist of our story presentation, is one of them, as well as a marking auxiliary parameters - frequency and power.

Speaking of power, it's not strange, it is able to influence the most important single laser pulse output most intuitive control variables. After testing found that when playing in stainless steel color, frequency and pulse width in a "contest", the parameters affect the frequency of color changes in some of the richer. If the frequency and power together, under certain conditions, such a law will appear the following: In the densely populated pitch, medium width, high-frequency (fill spacing <0.005mm; pulse width 45ns-100ns; frequency ≥300kHZ) of case, the power is increased by a small, stainless steel manifested in color showing very regular variation: yellow, red, blue, green, until the green gradually become darker. As shown below (@ 60ns, 0.001mm arcuate padding, F = 163mm field lens)

(Lateral power of 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%)As can be seen from the chart, with the frequency of the power changes, color changes show a certain regularity. This change in regular is filled pitch, the same applies. As shown below (@ 60ns, 0.005mm arcuate padding, F = 163mm field lens)

(Lateral power of 30%, 35%, 40%, 45%, 50%, 55%, 60%)At this point you can see, the premise of densely packed pitch, medium width, high-frequency, changes in the filling of the corresponding color change effect appear smaller, and more color change is caused by the frequency and power brought about by the action. In other words, the difference in color, mainly influenced by the laser pulse energy itself and its overlapping spot rate on steel, and stainless steel reaction to the color mode of going, is showing a picture as seen on the regular changes. Impact on the frequency and power of color changes described in this article, although not representative of the whole process of playing color color features, but in marking applications, but also in a certain range of parameters, and to provide some reference value .
