The development and breakthrough of domestic laser water chiller

 Laser is considered as one of the most representative novel processing technique. It realizes cutting, welding, marking, engraving and cleaning by using laser light energy on the work pieces. As a “sharp knife”, more and more applications of laser are found. For the time being, laser technique has been used in metal processing, molding, consumer electronics, automobile parts, aerospace, food & medicine and other industries.

2000 to 2010 are the 10 years when domestic laser industry began to grow. And 2010 till now are the 10 years when laser technique is thriving and this trend is going to last. 

In laser technique and its new products, the major players are of course the laser source and the core optical element. But as we know, what really makes laser becomes practical is the laser processing machine. Laser processing machines like laser cutting machine, laser welding machine and laser marking machine are the integrated products that combines optical, mechanical and electronic components. These components include machine tool, processing head, scanner, software control, mobile system, motor system, light transmission, power source, cooling device, etc. And this article is focusing on the laser-use cooling device. 

Domestic laser cooling units are under rapid growth

Cooling device is generally divided into water cooling machine and oil cooling machine. Domestic laser applications mainly require water cooling machine. The dramatic grow of laser machine helps promote the demand of the laser cooling units. 

According to the statistics, there are more than 30 enterprises which supply laser water chillers. Just like the normal laser machines, the competition among laser water chiller suppliers are also quite fierce. Some enterprises originally deal in air purification or refrigeration transport but later enter into the laser refrigeration business. As we know, industrial refrigeration is an industry of “easy at the beginning, but hard on the later stage”. This industry will not be this competitive for a long time and a small number of enterprises with superior quality product and well-established after-sales service will stand out in the market and accounts for the most of the market share. 

Nowadays, there are already 2 or 3 enterprises standing out in this fierce competition. One of them is S&A Teyu. Originally, S&A Teyu mainly focused on CO2 laser chiller and YAG laser chiller, but later expanded its business scope to high power fiber laser chiller, semiconductor laser chiller, UV laser chiller and later ultra-fast laser chiller. It is one of the few chiller suppliers that cover all types of lasers. 

During the 19 years of development, S&A Teyu gradually becomes a well-recognized brand by the laser machine suppliers and the laser end-users with its reliable performance and high stability. Last year, the sales volume reached 80000 units, which is leading in the whole country. 

As we know, one of the most important parameters of laser chiller unit is cooling capacity. Chiller with higher capacity can be used for higher power application. For the time being, S&A Teyu has developed air cooled recirculating laser chiller for 20KW fiber laser. This chiller has a proper design in the chiller body and the closed water loop. Temperature stability is another important parameter. For high power laser machine, it generally requires temperature stability to be ±1℃ or ±2℃. By precisely controlling the temperature for the laser machine, a laser water chiller can ensure the normal working and the long lifespan of the laser machine. 

Besides, S&A Teyu continues to improve the cooling technology and launches new products, including chiller specifically designed for UV laser marking machine and UV laser cutting machine and chiller specifically designed for handheld laser welding machine of 1000-2000W with temperature stability of ±1°C. 

S&A Teyu has never stopped in the road of innovation. 6 years ago in an oversea laser fair, S&A Teyu spotted a high precision ultra-fast laser with temperature stability of ±0.1°C. The cooling technology of ±0.1°C temperature stability had always been controlled by European countries, the U.S. and Japan. Realizing the gap with these countries, S&A Teyu decided to innovate its cooling technology to catch up with its foreign counterparts. During these 6 years, S&A Teyu experienced twice failures, which indicates the difficulty to achieving this high temperature stability. But all the efforts got paid off. At the beginning of 2020, S&A Teyu finally successfully developed the CWUP-20 ultra-fast laser water chiller of ±0.1°C temperature stability. This recirculating water chiller is suitable for cooling solid-state ultra-fast laser up to 20W, including femtosecond laser, picosecond laser, nanosecond laser, etc. Find out more information about this chiller at https://www.teyuchiller.com/ultra-precise-small-water-chiller-cwup-20-for-20w-ultra-fast-solid-state-laser_p242.html

The development trend and forecast of fiber laser cutting

 Fiber laser helps promote the development of the laser industry

Fiber laser is the most revolutionary technical breakthrough of the laser industry in the past 10 years. It has become the main industrial laser type and accounts for more than 55% in the global market. With fantastic processing quality, fiber laser has been widely used in laser welding, laser cutting, laser marking and laser cleaning, promoting the development of the whole laser industry.

China is the most important fiber laser market in the world whose market sales volume takes up about 6% of the world. China is also leading in the number of the installed fiber lasers. For pulsed fiber laser, the installed number has already exceeded 200000 units. As for continuous fiber laser, the installed number is nearly 30000 units. Foreign fiber laser manufacturers like IPG, nLight and SPI, they all take China as the most important market. 

The analysis of the development trend of fiber laser

According to the data, since fiber laser became the mainstream of the cutting application, the power of the fiber laser has become higher and higher. 

Back in 2014, laser cutting application became mainstream. The 500W fiber laser soon became the heated product in the market at that time. And then, the fiber laser power increased to 1500W very soon. 

Before 2016, the global major laser manufacturers thought that 6KW fiber laser was sufficient to meet most of the cutting need. But later, Hans YUEMING launched 8KW fiber laser cutting machine, which marks the beginning of the competition on high power fiber laser machines. 

In 2017, 10KW+ fiber laser was created. This means China entered the 10KW+ fiber laser era. Later, 20KW+ and 30KW+ fiber lasers were also launched one by one by laser manufacturers both home and abroad. It was like a competition. 

It is true that higher fiber laser power means higher processing efficiency and laser manufacturers like Raycus, MAX, JPT, IPG, nLight and SPI are all making contribution to the development of the high power fiber laser. 

But we must realize an important fact. For materials more than 40 millimeter wide, they often appear in high-end equipment and some special areas in which 10KW+ fiber laser will be used. But for most of the products in our daily life and industrial manufacturing, the laser processing need is within 20 millimeter wide and this is what 2KW-6KW fiber laser is capable of cutting. One one hand, laser machine suppliers like Trumpf, Bystronic and Mazak focus on providing laser machine with suitable laser power instead of developing high power fiber laser machine. One the other hand, the market selection indicates that 10KW+ fiber laser machine doesn’t have as many sales volume as expected. On the contrary, the sames volume of 2KW-6KW fiber laser machine has witnessed the rapid growth. Therefore, users would soon realize that the stability and the durability of the fiber laser machine are the most important thing, instead of “the higher the laser power, the better”. 

Nowadays, fiber laser power has become a pyramid like structure. On the top of the pyramid, it’s 10KW+ fiber laser and the power is becoming higher and higher. For the biggest part of the pyramid, it’s 2KW-8KW fiber laser and it has the fastest development. At the bottom of the pyramid, its’ fiber laser below 2KW. 

What S&A Teyu did to meet the medium-high laser power market need?

With the pandemic being controlled, the laser manufacturing need returns to normal. And 2KW-6KW fiber lasers are still the most needed one, for they can meet most of the processing demands. 

To meet the market need of medium-high power fiber laser, S&A Teyu developed CWFL series water circulation chiller, capable of cooling 0.5KW-20KW fiber lasers. Take S&A Teyu CWFL-6000 air cooled laser chiller as an example. It is specifically designed for 6KW fiber laser with temperature stability of ±1°C. It supports Modbus-485 communication protocol and is designed with multiple alarms, which can provide well protection for the fiber laser machine.

Semiconductor material development helps laser micro-machining business grow

Chip plays an important role in the high-end industries, such as smart phone, computer, home appliances, GPS device, etc. And the core device that makes the chip is generally dominated by the foreign manufacturers.

A few applications of semiconductor materials

Stepper is a mask exposure system. By using laser source to etch the surface protective film of the wafer, circuit will be formed with data storing function. Most of the steppers adopt excimer laser which can produce deep UV laser beam. The leading and major excimer laser manufacturer Cymer was acquired by ASML. And the new stepper would be EUV stepper which can realize process of below 10nm. But this technique is now still dominated by the foreign companies. 

But it is expected that China is gradually making breakthrough in chip making and later on realize self-production and mass production. Domestic steppers are also foreseeable and by then, the demand of high precision laser source will be increasing. 

Another wide application of semiconductor materials is PV cell industry which is the fastest growing clean energy market with best potential in the world. Solar cells can be divided into crystalline silicon solar cell, thin-film battery and III-V compound battery. Among these, the crystalline silicon solar cell has the widest application. Opposite to laser source, PV cell is a device that transmits light to electricity. Photoelectric converting rate is the standard to tell how good the PV cell is. The material and process technique in this area is quite crucial. 

In terms of cutting silicon wafer, traditional cutting tool was used, but with low precision and low efficiency and low yield. Therefore, many European countries, South Korea, the United States have already introduced high precision laser technique a long time ago. For our country, our production capacity of PV cell has reached half of the world. And in the past 4 years, as the PV industry has continued to grow, laser processing technique has gradually been used. Nowadays, laser technique is contributing to the PV industry by performing wafer cutting, wafer scribing, grooving of the PERC battery. 

The third application of semiconductor is PCB, including FPCB. PCB, which is the key component and the basis of all electronics, uses a large amount of semiconductor materials. In the past few years, as the precision and integration of PCB becomes higher and higher, tinier and tinier PCB will come out. By then, traditional processing and contact processing device will be hard to adapt, but laser technique will become more and more used. 

Laser marking is the simplest technique on PCB. For the time being, people often use UV laser to perform marking on the surface of the materials. Laser drilling, however, is the most common technique on PCB. Laser drilling can reach micrometer level and can perform very tiny hole that mechanical knife couldn’t do. In addition, copper material cutting and fixed fusion welding on PCB can also adopt laser technique. 

As laser enter micro-machining era, S&A Teyu promoted ultra-precise air cooled water chiller

Looking back the laser development in the past few years, laser has wide applications in metal cutting and welding. But for high precision micro-machining, the situation is the other way around. One of the reason is that metal processing is kind of a rough machining. But high precision laser micro-machining requires high level of customization and faces challenges like difficulty of developing this technique and lots of time spent. Nowadays, high precision laser micro-machining is mainly involved in consumer electronics like smart phone whose OLED screen is often cut by laser micro-machining.

In the coming 10 years, semiconductor material will become a priority industry. Semiconductor material processing could probably become the stimulus of the rapid development of laser micro-machining. Laser micro-machining mainly used short-pulsed or ultra-short pulsed laser, also known as ultra-fast laser. Therefore, with the trend of domestication of semiconductor material, the demand of high precision laser processing will increase. 

However, high precision ultra-fast laser device is quite demanding and it needs to be equipped with equally high precision temperature control device. 

To meet the market expectation of domestic high precision laser device, S&A Teyu promoted CWUP series recirculating laser water chiller whose temperature stability reaches ±0.1℃ and it is specifically designed for cooling ultra-fast lasers like femtosecond laser, nanosecond laser, picosecond laser, etc. Find out more information about CWUP series laser water chiller unit at https://www.teyuchiller.com/uv-laser-chillers_c4

Will increasing popularity of medical laser device provide new opportunity for laser cooling unit?

It’s been more than 60 years since laser technology was invented and it is widely used in industrial manufacturing, communication, medical cosmetology, military weapon and so on. As the COVID-19 pandemic is becoming more and more serious in the world, leading to the shortage of the medical equipment and more attention to the medical industry. Today, we are going to talk about the laser application in medical industry.

Laser eye treatment

The earliest laser application in medical industry is eye treatment. Since 1961, laser technology has been used in retina welding. In the past, most of the people used to do the physical labor, so they don’t have many eye disease. But in the past 20 years, with the advent of large screen televisions, computers, mobile phones and other consumer electronics, many people, especially teenagers have got the nearsightedness. It is estimated that more than 300,000,000 people are near-sighted in our country. 

Among various kinds of myopia correction surgeries, the most commonly used one is cornea laser surgery. Nowadays, laser surgery for myopia is pretty mature and gradually becoming recognized by most of the people. 

Medical laser device manufacturing

The physical features of laser enables it to perform ultra-precise processing. Many medical device requires high precision, high stability and no pollution in the manufacturing process and laser is no doubt the ideal option. 

Take heart stent as an example. Heart stent is placed in the heart and heart is the most important organ in our body, so it requires ultra-high precision. Therefore, laser processing instead of mechanical cutting will be used. However, general laser technique will produce a little burr, inconsistent grooving and other problems. To tackle this problem, many oversea companies began to use femtosecond laser to cut the heart stent. The femtosecond laser won’t leave any burr on the cut edge with smooth surface and no heat damage, creating superior cutting effect for the heart stent. 

A second example is the metal medical equipment. Many large medical equipment requires smooth, delicate or even customized casing, such as ultrasonic equipment, ventilator, patient monitoring device, operating table, imaging device. Most of them are made from alloy, aluminum, plastic and so on. Laser technique can be used to perform precise cutting on the metal materials and also perform welding. The perfect example would be fiber laser cutting /welding and semiconductor laser welding in metal and alloy processing. In terms of medical product out packaging, fiber laser marking and UV laser markinghave been widely used. 

Laser cosmetology has an increasing demand

With the increasing living standard, people become more and more aware of their appearances and they prefer their moles, patch, birthmark, tatoo to be removed. And that’s why the demand of laser cosmetology is becoming quite popular. Nowadays, many hospitals and beauty salons begin to offer the laser cosmetology service. And YAG laser, CO2 laser, semiconductor laser are the most widely used lasers. 

Laser application in medical area offers new opportunity for laser cooling system

Laser medical treatment has become an individual segment in medical area and it has developed very rapidly, which stimulates the demand of fiber laser, YAG laser, CO2 laser, semiconductor laser and so on. 

Laser application in medical area requires high stability, high precision and medium-high power laser products, so it is quite demanding on the stability of the equipped cooling system. Among domestic high precision laser water chiller suppliers, S&A Teyu is no doubt the leading one. 

S&A Teyu offer recirculating laser chiller units suitable for fiber laser, CO2 laser, UV laser, ultra-fast laser and YAG laser ranging from 1W-10000W. With further laser application in medical area, there will be more opportunities for the laser equipment accessories such as laser water chiller.
