Huakuo Technology produces ultrafast fiber lasers

The staff conducts product debugging in the clean room

In the exhibition hall of Guangdong Huaxue Photonics Technology Co., Ltd. (hereinafter referred to as “Hua Kuai”), a series of 3D printed models and laser-polished samples were placed. The staff is debugging an 8-inch wafer picosecond laser cutting system, in which the laser is the core component.

“We recently rented a 10,000-square-meter factory in the Torch Zone. After the new plant is put into use at the end of the year, it can mass produce 3,000 to 5,000 ultrashort pulse fiber (picosecond, femtosecond) lasers, becoming the leading laser production line in China. 1. "China Express Chairman Liang Chongzhi said that this also means that China has officially hatched after a few years of incubation.

The former company of Zhongshan Industrial Technology Research Institute was formerly known as Guangdong Hantang Quantum Optoelectronics Technology Co., Ltd. It is one of the few companies in China to master picosecond and femtosecond laser source technology. Its main business is ultra-fast laser, laser processing equipment, 3D. The development and production of printing equipment and 3D printing powder materials are expected to achieve explosive growth after the mass production of lasers.

Products are expected to break foreign monopoly

"We just want to do one thing, that is, the production of ultra-fast fiber lasers." Liang Chongzhi said that since its establishment in 2012, the company has been in the early stage of research and development. After moving to a new factory at the end of this year, it can achieve high repetition rate. Mass production of ultrashort pulsed fiber lasers.

For a laser, the light source is like the "engine" of the laser. According to the length of time, 1 nanosecond is 1 billionth of a second, 1 picosecond is one trillionth of a second, and 1 femtosecond is one trillionth of a second. The laser developed by Huaxue is mainly based on picosecond and femtosecond laser technology. What concept is this? Liang Chongzhi made an analogy. The nanosecond laser is like an "axe". The femtosecond laser is like a "scalpel". In the same time, the latter made the finished product more fine than the former.

As one of the greatest inventions of the 20th century, lasers have been around for more than 50 years, and laser pulses of the femtosecond magnitude were first implemented in dye lasers in the 1970s. In the past 20 years, femtosecond laser technology has developed very fast, and the innovative development and application development of ultrashort pulse laser is an important frontier in the international laser high technology and even modern science and technology.

"Like the cutting of the screen glass of the mobile phone, the marking of the logo on the metal casing, and the punching of the hole in the mobile phone are inseparable from the laser. The 3C electronics industry, the semiconductor industry, and the medical industry use more." Yaoming introduced that for the cutting, dicing, drilling, and high-end applications of metal, ceramics, wafers and other materials, picosecond and femtosecond lasers have broad application space.

"At present, about 90% of domestic picosecond and femtosecond laser technology light source devices rely on imports, and imported products are expensive. We must break the monopoly of foreign countries and make domestic ultra-fast fiber lasers. After 5 years of research and development investment of nearly 100 million yuan, now I have mastered the core technology and reached the stage of mass production.” Liang Chongzhi said that this technology has been developed from scratch and has complete intellectual property rights.

In fact, many areas of daily life are inseparable from the use of laser technology, such as decoration, kitchen and bathroom lighting, auto parts, metal furniture, electrical appliances, glasses, etc., these items need to be used for cutting, marking, welding, etc. A laser of the order of magnitude.

Take the YPP200 series of picosecond lasers developed by Huaxue as an example. This laser was recognized as a high-tech product last year. It is designed for micro-machining. It has short pulse duration, high peak power, small processing heat affected area, and long-term working stability. Good characteristics, suitable for glass marking, stainless steel coloring, PE film, battery pole film and other film cutting, drilling and other fine processing.

Academician leads the formation of technical research and development team

Speaking of the breakthrough of Huaxue picosecond and femtosecond laser technology, this is inseparable from its emphasis on scientific research and talent introduction. In 2013, after Liang Chongzhi decided to switch to a laser, he searched for relevant domestic talents, and finally introduced the professor of Peking University School of Information, Zhang Jiangang and his team, who studied the field for more than 20 years.

In 2016, Huaxue introduced the academician of the Chinese Academy of Engineering, Lu Bingheng, dean of the School of Mechanical Engineering of Xi'an Jiaotong University, and his team. The team pioneered the research of light-curing rapid prototyping manufacturing systems in China and formed a set of domestic leading product rapid development systems.

On the road of utilizing university resources, Huaxue has cooperated with Peking University, Huazhong University of Science and Technology, Xi'an Jiaotong University, Guangdong Academy of Sciences and other research institutes. After several years of sedimentation development, more than 70 patented technologies have been obtained. There are ultra-short pulse lasers, various series of metal 3D printers, multi-function laser processing machines and other products. Some of the products have reached the international leading level.

Just as the ultra-fast fiber laser can be mass-produced, the company has also completed the industrial registration of the new name “Hua Kuai”. The original name “Guangdong Hantang Quantum Optoelectronics Technology Co., Ltd.” will no longer be used. When talking about changing its name, Liang Chongzhi said that Huawei is one of the company's customers. The TRUMPF Group is one of the global leaders in laser technology. The idea of ​​“Hua Kuai” is to encourage enterprises to continue to learn from the target companies.

With the results of scientific research, how to combine research results with applications is a question that many companies think about. Since its establishment, Huaxue has paid attention to the application of technological achievements, and has cultivated different subsidiaries for different fields of application, and internally formed an industrial extension chain with various directions and complementary to each other.

Since its establishment, China Express has successively established Guangdong Liangze Laser Technology Co., Ltd., Zhongshan Hantong Laser Equipment Co., Ltd., Guangdong Hanbang Laser Technology Co., Ltd. and Guangdong Hantang Rapid Manufacturing Application Technology Research Institute.

"1+3" mode outlines the development roadmap

At present, Huaxue has formed the structure of “one research institute + three application companies”, and each subsidiary has areas that focus on development. For example, Qunzawa Laser is mainly engaged in the development of picosecond and femtosecond lasers and providing technical solutions; Hantong Laser is mainly engaged in the production of laser welding machines and marking machines; Hanbang Technology mainly produces and applies metal 3D printing equipment. Han and Tang Dynasties research and development and project incubation.

Among them, Hantang Rapid Manufacturing Research Institute plays the role of R&D base, mainly providing cutting-edge rapid manufacturing technology, including rapid prototyping technology, rapid mold technology and ultra-high-speed cutting technology; Huaxue provides the project operation framework and forwards the technology. The extension of the industrial chain.

Among several subsidiaries, Hanbang Technology has made great achievements in metal 3D printing applications. In 2013, Hanbang Technology successfully developed the first industrial grade metal 3D printing equipment in China and launched it in the second year. In 2016, the second generation of metal 3D printing equipment, special equipment for the dental field, and special equipment for the aerospace industry were introduced.

Nowadays, in the field of 3D printing medical applications, Hanbang Technology has cooperated with many top three hospitals and medical units to print out bone plates, implants, auxiliary guides, instrument tools and other products with self-developed metal 3D printers. Hundreds of clinical trials have accumulated rich experience in the application of metal 3D printing in orthopedic applications, and promoted the application of domestic 3D printing in clinical medicine.

For example, Hanbang Technology sent professional technicians to Guangxi Guigang People's Hospital for several months, using metal 3D printing equipment and application technology in the field of orthopedics to support a number of surgical programs and undertake printing work. In the course of the project, Hanbang Technology also cooperated with Guangxi Guigang People's Hospital, Basic Medical College of Southern Medical University, and Xiangya Second Hospital of Central South University to complete the topic "Basic and Clinical Research of 3D Printing Technology in Orthopedic Restoration and Reconstruction". In May of this year, Hanbang Technology officially put into operation at the production base of more than 20,000 square meters in Nantou Town, which laid the foundation for the further development of the company.

It is in this development mode that in 2016, Huasheng Group achieved an output value of 80 million yuan and won the second prize in the Guangdong Innovation Zone of China Innovation and Entrepreneurship Competition. The Zhongshan Division won the special prize and won the new research and development institution of Guangdong Province and Zhongshan Engineering Technology. Research Center, Zhongshan Academician Workstation, Zhongshan Collaborative Innovation Center and other titles.
