Laser marking machine outperforms silk printing machine in many different ways

 Laser marking machine can leave permanent marking on the material surface. The surface of the materials will vaporize after absorb the laser energy and then the inner side will come out to realize the marking of beautiful patterns, trademarks and characters. Currently, laser marking machines are applied in areas which require higher precision, including electronics, IC electric device, hardware, precision machines, glasses & watches, jewelry, automobile accessory, construction, PVC tubes and so on. In today’s world, novel technology is rising and gradually replacing the traditional processing method with the superior performance. Ever since the laser technology was invented, it has attracted many professionals from different industries with excellent processing performance, providing great flexibility and more opportunity for creative processing. The current laser marking machine feature high precision, non-contact quality, lasting marking, high processing efficiency and these features are what silk printing machine can not achieve. Next, we are going to compare laser marking machine and silk printing machine in 5 different ways.


1.Speed
Laser marking machine uses high energy laser light directly to perform processing. While traditional silk printing machine needs quite a lot of procedures. In addition, laser marking machine doesn’t need consumable items and people just need to adjust the pattern on the computer and then the pattern will come out directly. As for silk printing machine, users have to worry about if the net is blocked or if there is anything broken after printing. 

2.Affordability 
Comparing with silk printing machine, laser marking machine used to be much higher. But now, with more and more domestic laser marking machine manufacturers developing their own laser marking machines, it becomes less expensive and more affordable. 

3.Procedures
For laser marking machine, since it combines the software control technique, users just have to operate the laser marking machine through the computer, saving many complicated procures. In terms of silk printing, users need to pick the ink first and then put it on the screen and have to be very careful with the details, which suggests pretty much procedures. 

4.Safety
Laser marking machine won’t produce any pollutant during operation and will not do harm to people. As for silk printing machine, since it needs consumable items, it will cause pollution to the environment. 

To sum up, laser marking machine outperforms silk printing machine in many different ways and will have bigger demand in the coming future. As the demand of laser marking machine grows, the demand of its accessories also grows. Among those accessories, industrial water chiller system is no doubt the critical one. It plays the role in maintaining normal temperature for the laser marking machine. S&A Teyu designs and develops industrial water chiller system which is able to cool laser marking machines of different kinds, including CO2 laser marking machine and UV laser marking machine. Find out more details for these water chillers by sending e-mail to us at marketing@teyu.com.cn

How many kinds of laser marking machines are there? Do all of them need to be equipped with water cooling industrial chiller unit?

 Laser marking machine uses laser light to leave a permanent marking on different kinds of objects. Since it is non-contact, it won’t damage the surface of the object. There are 3 commonly used laser marking machines: CO2 laser marking machine, UV laser marking machine and fiber laser marking machine. However, not all of them need to be equipped with water cooling industrial chiller units. For fiber laser marking machine, since its laser power is pretty small, air cooling suffices to cool it down. As for CO2 laser marking machine and UV laser marking machine, water cooling industrial chiller units are the necessary cooling device. If you are not sure what water cooling industrial chiller unit model to choose for your laser marking machine, you are welcome to leave a message in our official website at https://www.teyuchiller.com


After 18-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization. With cooling capacity ranging from 0.6KW to 30KW, our water chillers are applicable to cool different laser sources,laser processing machines, CNC machines, medical instruments, laboratory equipment and so on.

Industrial Cooling System CWUP-10 Impressed a Portuguese User with Ultrahigh Precision

When you buy some packaged food, what do you care the most besides its contents? Production date, isn’t it? However, before the packaged food reaches the consumers, they need to go through a long journey - manufacturer, distributor, wholesaler, retailer and then finally consumer. In the bumpy long transportation, the production date on the food package can easily become blurred or even gone because of abrasion. Many food companies notice this problem and they introduce UV laser marking machine to solve this. Mr. Lopes’ company is one of them.

Mr. Lopes is the purchasing manager of a food company in Portugal. He learned that UV laser marking machine can do the lasting production date marking without hurting the surface of the food package, so he purchased 20 units of the machines. What came along with those UV laser marking machines were S&A industrial cooling systems CWUP-10.

S&A industrial cooling system CWUP-10 is specially designed for cooling UV laser and characterized by ±0.1℃ temperature stability. This indicates extremely small temperature fluctuation so that the laser output can be maintained, leading to excellent marking effect. Mr. Lopes said, “I didn’t expect the industrial cooling system CWUP-10 can be that precise. It really impressed me!” Now, industrial cooling system CWUP-10 has become the indispensable cooling device in his company’s production line.

What could be the reasons for poor cooling of performance of laser diamond marking machine industrial chiller?

Cooling performance of laser diamond marking machine industrial chiller becomes poor. The reasons could be:
1.The temperature controller of the industrial chiller is broken and unable to control the water temperature;
2.The cooling capacity of the equipped industrial chiller is not big enough;
3.If this problem happens after the chiller is used for a period of time, the reasons could be:
A.The heat exchanger is too dirty. Please clean it accordingly;
B.The industrial chiller leaks refrigerant. Please find and weld the leakage point and refill with refrigerant;
C.The ambient environment is being too hot or too cold so the industrial chiller can not meet the cooling requirement. It’s suggested to choose a bigger industrial chiller. 

After 18-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization. With cooling capacity ranging from 0.6KW to 30KW, our water chillers are applicable to cool different laser sources,laser processing machines, CNC machines, medical instruments, laboratory equipment and so on.

Why the water level of the water chiller which cools laser barcode marking machine is down to the red area(low water level)?

The water level of water chiller which cools laser barcode marking machine down to red area may be possibly due to the following situations:

1.There’s not enough purified water/distilled water inside the water tank;
2.The water chiller is leaking.
It is suggested to fill the water chiller with purified water/distilled water to the green area(normal water level) first and then observe if there is any leakage.
 
In respect of production, S&A has invested the production equipment of more than one million RMB, ensuring the quality of a series of processes from the core components (condenser) of industrial chiller to the welding of sheet metal; in respect of logistics, S&A has set up logistics warehouses in the main cities of China, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of after-sales service, the warranty period is two years.
