When the temperature is low in winter, in order to ensure the normal use of the laser machine and equipment maintenance, antifreeze will be added to the water tank. So, what happens in hot climates? When working in hot weater, as long as the water tank cannot reach the cooling effect, the equipment will alarm and suspend operation. How to avoid similar situations from happening? The water tank is the key, the size of the water tank determines the operating time to maintain normal temperature. The smaller the water tank, the weaker the constant temperature capability, and the water tank larger the stronger, and there is also certain gap in cost. In order to reduce production costs, many manufacturers also equip with small water tanks, which is why there are price differences.

Laser marking is also called laser coloration, charring, or laser dark marking, and is attained when the laser beam changes the surface of the material. A low-powered beam is required to complete this slight alteration of the surface. High contrast marks can be created through laser marking without damaging the material. When laser marking a plastic surface, it can be called “charring,” while annealing is commonly used for laser marking metals. There are four main types of laser marking.


Metal laser engraving machines are generally fiber laser engraving machines, some people also call red light machines. The wavelength of this red light machine is 1064nm, which can be absorbed by metals and some non-metals. Its effect on metals is very obvious. By adjusting the parameters, it can print black and white content and the power of the laser. Metal laser radium engraving machines can also engrave some plastics, but the effect is not ideal, because plastics are heat-sensitive materials, the content printed by this machine will have a very obvious feeling, and the fonts are not fine enough. The plastic laser laser machine is actually an ultraviolet laser engraving machine. The light it emits is purple, so it is also called a purple light machine. It is mainly used for laser engraving on various plastic products.

Laser Marking Mechine Applications:
1. Ink and Paint: cell phone battery labels, panels, cell phone keys, daily necessities accessories, etc.

2. Ceramic, EP Material Laser Marking: electronics, component packaging, IC, etc.

3. Plastic Products: electrical appliances shells, electronic products, and other products flow number, LOGO, etc.

4. Metal and Surface: stainless steel, copper, aluminum, and oxidation plating, commonly used in hardware, electrical appliances, cell phone shells, etc.

5. Keyboard and Keys: keyboard, keys, and other fine markings.

Laser marking may also be used to create ID cards and smart cards as it is fraud-proof. The process is used in the food, automotive, aerospace, medical, electronics, advertising, semiconductor manufacturing industries.

1. Power density
High power density is beneficial for material removal processing, such as hole opening, laser cutting, and manual engraving.
2. Single pulse waveform
When the high-strength beam hits the surface of the material, the energy reflection that appears on the metal surface will be destroyed, and the transmittance changes with the surface temperature. Within a single pulse duration, the transmittance of the metal material changes.
3. Pulse width
Duty cycle is one of the key parameters of pulse welding. It is not only a key parameter different from raw material removal and raw material melting, but also an important parameter to determine the cost and volume of production equipment.

500W fiber laser cutting machine to cut stainless steel and carbon steel materials, and the thickness is generally about 3mm~6mm.Factors affecting the processing thickness and speed of fiber laser cutting machine:
1. Different materials
The stainless steel material is very hard, generally can be cut into 3mm thick, the surface is very rough and the speed is slow.
2. Related accessories of cutting machine.
3. Equipment maintenance
The laser machine needs regular maintenance, and a good working environment is benefit for the stable operation and service life of the equipment.

In sheet metal laser manufacturing, the quality requirements for welding strength and appearance are different according to different products. Laser welding has a small heat input, and the heat-affected zone is extremely small, which can effectively improve the welding quality and reduce the time for follow-up work. And some internal structural parts or parts that need to be sprayed later have higher requirements for welding strength and welding speed. DP laser welding machine is undoubtedly the best choice.

For different materials, choosing different laser power waveforms can also make the welding effect more delicate. Sometimes even materials that cannot be welded by traditional methods can be obtained by changing the laser power waveform.When selecting the laser output power waveform, under the premise of outputting the same laser energy, the wider the duty cycle, the larger the welding spot; the higher the peak output power of the laser output power waveform, the deeper the welding spot. Customers can explore in the application process to explore the laser output power waveform suitable for your products.

1. The current cutting capacity of laser cutting machines in the industry:
Carbon steel is 36mm. If the 36mm steel plate is made of high-quality materials, the machine performance is good, the graphics are not complicated, and the cutting quality is good. Stainless steel is 25mm. However, mild steel is less than 25mm and stainless steel is 16mm or less.
2. The maximum stroke of the laser cutting machine
There are currently two types of laser metal cutting machines: one is desktop, the general effective cutting range is 1.5 * 3 m, 2 * 4 m; the other is gantry type laser cutting machine, which effective cutting width can be 2~6 meters, and the length can be 10 meters. It has the same structure as flame cutting machine flame cutting machine and plasma cutting machine.
3. Speed and accuracy
If the main cutting board is lower than 6mm, it is recommended to purchase a desktop laser cutting machine that is faster and more accurate than the gantry type.
