Why is the UV laser marking ma
Why is the UV laser marking machine so much more expensive than the fiber laser marking machine? In terms of some special materials, the UV laser marking machine is better than the fiber laser marking machine, such as: ABS, PP, UV, etc. Why is this? The main reason is that the light waves of UV and fiber are different. The wavelength of UV is 355MM, which is a short wave. One characteristic of short waves is that they will not produce too much thermal effect on the material. The wavelength of the fiber laser marking machine is 1064NM, which belongs to infrared light at noon, and it is easy to produce high temperature. If there are materials that are sensitive to heat, they will feel burnt. However, on metal, the fiber laser marking machine will not produce any significant changes to the metal surface. The application of UV laser marking machine in metal materials is still relatively rare. Nowadays, fiber laser marking machine is the mainstream in the market for metal material marking. ...

Will laser equipment be harmfu
The emergence of laser equipment has promoted the development of many processing and manufacturing industries. Nowadays, laser marking machines have become the new elites in the identification industry. While being convenient, manufacturers and workers all hope to have a clean and comfortable working environment. Can laser marking machines do this? Compared with other types of equipment, will laser marking machines cause any harm to the human body? In fact, no matter what kind of work you do, you must have a reasonable rest time, otherwise it will cause harm to the body. Everyone calls it "occupational disease", such as: IT people face computers every day, driving, chemical product processing, etc., unreasonable work arrangements will lead to various morbidities. The main thing about laser marking is radiation, but you can rest assured that the radiation of laser marking machines is very small, even smaller than the radiation of the mobile phones we use daily. The use of lasers also ha...

So how to clean the field lens
The surface of the laser lens is coated. Be careful when cleaning to avoid scratching the mirror surface. Cleaning requires the use of a cleaning agent to rotate from the center of the lens to the outer periphery. Please securely fix the lens to the main body during installation. It is recommended to clean the lens surface every day and remove the lens for cleaning every two weeks. The order of taking and placing the lens is to hold the outer side of the f-胃 lens and rotate it counterclockwise. The lens surface can be removed from the main body. The f-胃 lens needs to be cleaned regularly. If the lens becomes dirty, it will lead to a decrease in laser performance and failure.

How to care for the laser mark
Laser marking machines are common equipment in processing plants today, and they don鈥檛 have any wearing parts, but there are still many accessories that need to be cleaned regularly, and you need to be extra careful, because once damaged, they can鈥檛 be used. The field lens of the laser marking machine needs to be cleaned regularly, because it is outdoors, and there will be dust when marking. If it is not cleaned for a long time, there will be a layer of dust on the lens, which will affect the light quality of the laser marking machine, and in serious cases, the lens may be burned.

Can plastic laser welders weld
Not necessarily. There are many factors involved, such as the thickness of the plastic, the light transmittance of the plastic, the material properties of the plastic itself, etc.

What quality controls are in p
Use a thermometer to detect the temperature of the welding pool in real time through infrared rays. Note that the temperature detected by the thermometer is a comparative value, not an actual value. The common quality monitoring method in the automotive parts industry is to use a displacement sensor to monitor the depth of welding collapse. Use a force sensor to monitor welding pressure.

How to determine the thickness
General principle, amorphous plastics such as PC, PMMA and ABS, etc., the mother without adding color is transparent, and there is no specific requirement for its thickness. But the thickness of welding semi-crystalline plastics generally does not exceed 2mm, because the mother without adding color is milky white or milky yellow. When containing glass fiber plastic, the thickness should be as small as possible on the basis of ensuring the mechanical properties of the parts. 1. It is recommended to use PBT material with a thickness of less than 1.5mm. 2. Using nylon material, the thickness is recommended to be less than 2mm. 3. Using POM material, the thickness is recommended to be less than 3mm.

What is a typical weld design?
For welding electronic components such as EPB electronic parking brakes and thermal management expansion valves, the following weld design can be used. The weld width is 1.2mm, the weld depth is 0.4mm, and there are ribs inside and outside to prevent overflow and extrusion.

What problems does low laser p
A series of process problems such as shrinkage marks, burns, and poor welding may occur. Pay attention to black nylon or PBT materials, whose production and injection molding process easily lead to unstable laser penetration rate of the workpiece after injection molding. Laser penetration detector can be used for detection.

What is the principle of plast
Laser transmission welding is when a laser beam penetrates an upper transparent component and is subsequently absorbed by the lower laser-absorbing component. When the laser energy is absorbed by the dye or additive particles, it is converted into heat energy. The surface of the absorbing component melts and the heat is transferred to the upper transmissive component by heat conduction. Before welding begins, the two components are in contact with each other under the action of an external force. During welding, the components are locally heated, which causes thermal expansion of the material and generates internal welding pressure. The two components are firmly welded together under the combined action of internal and external welding pressures. The relative movement of the laser beam and the welding components forms the weld.
