In Chengdu Economic Development Zone, there is an enterprise specializing in the research and production of optoelectronic glass materials-Chengdu Guangming Optoelectronics Co., Ltd. (hereinafter referred to as "Chengdu Guangming"). At present, this enterprise produces and sells more than 10,000 tons of optical glass a year, accounting for more than 40% of the global market share, and the production and sales volume of products ranks first in the same industry.

Chengdu Guangming is an enterprise focusing on the R & D and production of optoelectronic glass materials. From the establishment of the factory in Chengdu in 1956 to the industrial production of the first crucible in New China in 1958, Chengdu Guangming has ranked first in the world in terms of production and sales, shining on the global stage and becoming a veritable global industry "champion".

Walking into the Chengdu Guangming production workshop located in the economic development district of Chengdu, there is no imagined crowded scene, replaced by a series of automatic equipment, such as automatic batching machine, automatic feeder, automatic annealing furnace, automatic packaging machine and so on. At the outlet of the product, glittering and translucent photovoltaic glass slowly flows out, and workers cut according to a certain size, and mark its unique "identity code" on each product.

At present, the company produces more than 300 varieties of optical glass, which are widely used in aerospace, new energy and other major national engineering fields, as well as imaging projection, security monitoring, environmental awareness and other areas of daily life.

Liu Zhenyu, general manager of Chengdu Guangming, said that at present, the company's annual production and sales of optical glass is more than 10,000 tons, accounting for more than 40% of the global market share. Since 2005, product production and sales have steadily ranked first in the same industry.

Taking the core components of the mobile phone camera as an example, the near-infrared filter glass developed and produced by Chengdu Guangming can isolate stray light that is not needed in the imaging process and greatly improve the imaging quality of mobile phones. this technology has been applied to more than half of the world's mobile phones. In other areas of optical imaging, Leica, Swarovski, Canon, Nikon, Sony, Tenglong, Shunyu, Epson, Huawei, OPPO and other international well-known brands are also Chengdu bright partners.

At present, Chengdu Guangming has formed the strongest variety matching ability in the world. in addition to providing product strips, it can also provide different forms of products such as bars, shaped materials, aspheric preforms, aspheric lenses and so on. At present, the products have been exported to Europe and the United States, Japan and South Korea, Southeast Asia and other places.

Focusing on the two main industries of optoelectronic glass materials and precious metals, after more than 60 years of development and innovation, gradually become China's leading, international influential professional optoelectronic materials R & D and manufacturing enterprises and China's leading platinum group metal purification and manufacturing enterprises. -- Liu Zhenyu said

Industry leader, global sales first, what does the enterprise rely on to maintain the leading position in the industry? The answer is: scientific and technological innovation.

Scientific and technological innovation will bring new technologies and products for enterprises, and provide development power for enterprises in the fierce market competition. At the same time, it can also promote the industrial upgrading of the industry and maintain the trend of healthy development.

Liu Zhenyu said that for a long time, Chengdu Guangming's annual science and technology investment accounted for more than 7% of its sales income, and increased year by year.

Last year, Chengdu Guangming won the special prize of the 2022 Sichuan Patent Award.

The patented products involved in the award-winning 'optical glass and optical elements' have solved the problem of localization of high-end phosphate optical glass materials needed for national construction and the development of the optoelectronic industry. from the formulation research and development, mass production process research, testing technology development and other aspects, all-round breakthrough of foreign enterprises' technical and patent barriers. Yuan Wanlin, deputy director of Chengdu Guangming Optoelectronic Technology Center, said

It is understood that Chengdu Guangming has the first national enterprise technology center in the same industry in China, has set up a complete innovation platform and innovation system, and continues to carry out research and development on the formulation, mass production process and testing means of cutting-edge optoelectronic materials, and its R & D capability is second to none. Up to now, the company has applied for nearly 1800 patents, including nearly 1200 invention patents, which have been successfully listed as the national special optical glass technology innovation center.

Not long ago, good news came from Chengdu Guangming. The construction project of the R & D building of the Institute of Optoelectronic Materials will start construction in Chengdu Guangming Industrial Park, and will build a R & D building with the functions of scientific research and development, experimental research and so on. It will provide scientific research and test sites for the development of optical glass materials, functional glass materials, special glass materials, in-depth research on new glass manufacturing processes and equipment, and the training of high-level R & D personnel. Further enhance the company's technological leadership.

In the next step, the company will focus on national strategy and industry demand, focus on the formulation and process research and development of optical glass materials, functional glass materials and precious metal materials, strengthen scientific and technological innovation, and continuously enhance the core competitiveness of enterprises. -- Liu Zhenyu said
