How to make white when the laser marking machine sprays plastic

Laser marking machine.

Whitening on spray materials is easy to achieve.

The laser power can be adjusted a little smaller, and the laser speed can be adjusted a little faster. Reducing the laser power is to avoid the laser penetrating the spray layer.

Turning the laser speed up is to avoid the laser staying in the spray layer for too long, which can lead to color darkening. Achieving the ideal state depends primarily on the selection process of the laser printer's parameters. With a clear understanding of the material, the application and the required marking, the laser printer can print high-quality markings on a wide range of materials.

Different combinations of specific wavelengths, marking heads, and selected lenses can produce different marking effects on a given material. As line speeds increase and heavier production tasks are being handled, manufacturers need simpler, more efficient lasers to deliver high-quality coding for their products. Compared with inkjet marking, laser marking grooves) have the following advantages:

A wide range of applications and a wide range of materials (metal, glass, ceramics, plastics, leather, etc.) can be marked with permanent high quality.

To learn more about laser printers, we recommend Videojet laser printers. Videojet offers a wide range of high-performance CO2 lasers for large-format substrates and easy integration for virtually any application. Lightweight carbon dioxide.

The laser printer is designed for large-format coding needs, and has enough flexibility with simple setup and operation. Videojet laser printers are simple to operate, fully automatic laser machines, and are ideal for the best barcodes.

What color is outside? Another thing to look at the material is whether there is a layer of plating on the outside.

The laser marking machine can be color-printed.

The specific color of the laser marking machine depends on the parameters and the material itself, and the laser powder is used to match the color of the laser marking machine. Using some specific materials or marking processes, the correct operation of the diode pump to mark the substrate can not only produce a clear and beautiful black and white effect, but also make a color effect identification.

Like aluminum laser blacking, it is difficult for ordinary laser marking machines to achieve stainless steel laser color marking process. The special laser for color marking is optional, so that the pulse width can be adjusted, and the color marking effect is better.

1. Import ** into the main control computer of the laser marking machine.

Select the Bitmap command in the drawing menu. An input dialog box pops up, asking the user to select the bitmap they want to import. The bitmap formats supported by the system are all distributed into points with similar resolution according to their own arithmetic functions to complete laser marking.

2. Adjust the size of the material according to the size of the material we want to print.

3. Set the relevant parameters of the engraved photo, this step is more critical, it will directly affect the good or bad effect of marking.

4. The setting speed of the laser parameters on the right side of the software is generally about 1000, the power is smaller first, 35% is tested first, and the color is not clear enough to increase the power, and the frequency can be used at a low frequency of 30.

5. After adjusting the appropriate marking parameters, it is OK to mark the marking.

In order to ensure the clarity of the marking, please select the pixel ratio is relatively high**; When choosing the marked **, if you want to print out the **high degree of restoration, you need to choose the ** with higher contrast.

Abstract:Laser marking machine is currently the most advanced laser equipment, is a new type of high-tech machine, it helps to reduce operating costs, with the smallest consumables can be completely printed, and simple to operate. How does a laser marking machine work?

What are the precautions for the use of laser marking machine? Let's find out. 1. How to operate the laser marking machine.

Check that the waterway and circuit are correct before turning on the machine. The boot sequence is:

1. Turn on the incoming power supply and turn on the key switch. At this time, the exhaust and refrigeration system of the machine is energized, and the ammeter shows a value of about 7A.

2. Wait for 5 10 seconds, press the trigger button on the external control panel, the ammeter shows the value of zero, 3 5 seconds later, the krypton lamp is ignited, and the ammeter shows the value of 7a.

3. Turn on the galvanometer power.

4. Turn on the computer and call up the required marking file.

5. Adjust the laser power supply to the working current (10 18A), and you can start marking.

After the marking is completed, the power supply of each component is turned off in reverse in the above order

1. Adjust the working current of the laser power supply to the minimum (about 7A).

2. Turn off the computer.

3. Turn off the galvanometer power.

4. Press the stop button.

5. Turn off the key switch.

6. Disconnect the incoming power supply.

2. Precautions for the use of laser marking machine.

1. The laser marking machine should be used in a dust-free, 10-35 environment as much as possible to keep the optics dry and dust-free. It is usually necessary to ensure a separate closed workshop pants digging song, to ensure a constant indoor temperature, the floor should have floor paint or tiles, and install air conditioning.

2. It is strictly forbidden to start the laser power supply and Q switching power supply when there is no water or abnormal water circulation.

3. The Q power supply is not allowed to work at no load (that is, the output end of the Q power supply is suspended).

4. If there is an abnormal phenomenon, first turn off the galvanometer switch and key switch, and then check.

5. It is not allowed to start other components before the krypton lamp is ignited to prevent high-voltage intrusion and damage to the components.

6. Pay attention to the suspension of the output end (anode) of the laser power supply to prevent ignition and breakdown with other electrical appliances.

7. It is best to use deionized water for cooling water in the circulating water tank, if there is no deionized water, distilled water can be used instead. The circulating cooling water should be replaced in time after a period of use (it is recommended to change the water at least once every two weeks) so as not to affect the laser efficiency.

Hello, dear. The yellowing of the font typed by the laser marking machine may be caused by the following reasons:1

The quality of the marking material of the laser marking machine is not good, and it is not suitable for laser marking technology. Some plastic materials are not resistant to ultraviolet rays and temperature changes, which will make the engraved font yellow. 2.

Improper adjustment of the marking parameters of the laser marking machine. If the settings are not right, such as power, speed, frequency, etc., then the font color will not only be yellow, but the scan line will not be smooth. To solve these problems, you can try the following methods to adjust:

1.Determine the right materials. Choose the right materials for the laser marking machine technology, such as metals, ceramics, high-temperature plastics, glass, etc.

2.Adjust the marking parameters. Try to modify the marking parameters of the laser marker, such as reducing the power, increasing the speed, adjusting the frequency, and find the best combination to ensure the quality of the marking.

3.Excellent workout technique. Before operating the laser marking machine, make sure you understand every operation instruction and carry out technical training and use.

When marking the anterior skin, it should be kept clean, stable and at an appropriate distance to ensure that it does not cause too much damage to the material. 4.Use relevant software.

The driver software of some laser markers will provide font style and color adjustments. You need to try to use special adjustment software to adjust the color value and other attributes of the yellowed font to achieve better results.
