On March 7, 2019, Shenzhen Sunshine laser & electronics technology Co., Ltd. successfully completed the acquisition of Chengdu Tongyu Aviation Equipment Manufacturing Co., Ltd. in Shenzhen.

Founded in 2013, Chengdu Tongyu Aviation Equipment Manufacturing Co., Ltd. is a component manufacturing service provider for the domestic aviation industry. The company is mainly engaged in the development and manufacture of aviation aircraft parts. The business covers CNC machining, tooling, mold design and manufacturing, metal grade 3D printing, aviation ducts and sheet metal forming. The company's aerospace components are used in many types of military aircraft, drones, transport aircraft, missiles, domestic civil aircraft and Boeing, Airbus subcontracted passenger aircraft, transport aircraft. The company uses innovative processes to solve the complex structural and curved surfaces of various difficult-to-machine materials such as titanium alloys, aluminum alloys, and high-temperature nickel-based alloys. In addition, the company also explored autonomous aerospace metal 3D printing laser selection melting technology, laser deposition 3D printing technology for the overall printing of ultra-complex structural parts. Tongyu Aviation has certain technical reserves and operating results in the fields of aerospace component manufacturing, tooling and mold design and manufacturing, and has strong market competitiveness in aerospace applications.

In recent years, China's aerospace industry has advanced by leaps and bounds. Tongyu Airlines has good technical strength and profitability in the aerospace industry. This cooperation will expand Sunshine Laser's business scope into aerospace applications, which will help improve the company's profitability and maintain the company's sustainable development.

Since 2013, Sunshine Laser has been committed to industrial 3D printing process technology research and development and industrial applications, and is the first in China to develop industrial 3D printing business. The advantage of 3D printing in the aerospace industry is the ability to redesign the entire system and components to achieve precise configuration and functional requirements. In the aerospace component manufacturing industry, the above advantages are more significant. After the completion of the acquisition, Tongyu Airlines will gradually introduce the company's industrial 3D printing process. The company's 3D printing business and market will further expand into the aviation component manufacturing industry. The injection of new assets will strengthen the company's advantageous business and enhance the company's comprehensive strength. .

In addition, the application of laser technology is an important breakthrough in the development of the defense industry in the future. As an important strategic layout for the company's development, Tongyu Airlines has the opportunity to cut into the military industry platform by laser innovation and application technology, which is the key to the future development of the company, to achieve the industrial breakthrough of the company's advantageous business.

The acquisition is an important step in Sunshine Laser's business strategy. After the acquisition, Sunshine Laser enters a new field of aerospace applications, further enhancing the company's business scale and profitability, and enhancing the company's ability to respond to the changing market's risk resistance.
