Some of our certificates and honors

Chengdu Greenstone Laser Technology Co., Ltd. is located in Tianfu New District, Chengdu, Sichuan Province, China. It is a pioneer in China’s industrial laser metal processing. It mainly serves high-tech industries such as aerospace, rail transportation, electric power, petrochemicals, and mold manufacturing.
The company has the core technology of laser metal direct forming (metal 3D printing), which fills the gap in the development technology of key parts of domestic aircraft engines and has achieved significant economic and social benefits. The first domestic high-vortex blade of an aircraft engine was successfully repaired at Greenstone, extending the life of the blade by more than 2 times.
Greenston pioneered the successful application of laser additive manufacturing technology to the repair of hydropower units, and the 24-hour mobile on-site repair solution successfully solved the repair problem of oversized parts similar to hydropower units that are difficult to disassemble, have high replacement costs, and have long transportation cycles.
The company adheres to the corporate culture of “pragmatism, excellence, wisdom, and innovation” and is committed to providing customers with high-quality services, saving time and economic costs, and jointly building a better future. Since its establishment in 2012, it has successively won certificates and honors such as “National High-tech Enterprise”, “National Military Standard Quality Management System Certification”, “AS9001 Quality Management System Certification”, “Top Ten Innovation and Entrepreneurship”, “Huayang Star”, we and our related companies have more than 800 industry technology patents
